Question 3:
What areas do you service (e.g., Kirkland, WA metro, specific radius, fleet nationwide)?
Currently Mechanical Triage operates on the Eastside, from Kenmore and Woodinville, down to Bellevue. With quick expansion over the next few months, we should be able to service the larger Puget Sound region.
Question 4:
What are your hours of operation, and do you offer emergency or 24/7 service?
Mechanical Triage Services main hours are from around 7am to 6pm, Monday through Saturday. Emergency hours are possible, and partnering shops have independent hours. If you have an emergency 24/7 issue, we can direct you to the proper sources to resolve your issue.
Question 5:
How much does a typical service or diagnostic visit cost, and what payment methods do you accept?
While typical mobile repair diagnosis and services usually start at around $200, referral services are usually free. There may be a diagnosis fee associated for hands on triage and refferal coordination. Types of payments accepted vary greatly, but a sure bet is usually cash or card. (Some service providers accept alternative forms of payment such as Zelle, Apple Pay, check, etc)
Question 6:
Do you provide a warranty on parts and labor, and what does it cover?
Mechanical Triages specific warranty on parts and labor is 12 months, 12,000 miles. (But only for parts we provide) There is no warranty provided by any service provider for customer supplied parts. Other service providers have their own specific warranties, that may cover broader timespans or mileages, depending on the specific repairs or components.
Question 7:
Can I supply my own parts, or do you require using your parts/suppliers?
For warranty purposes, most all service providers associated with Mechanical Triage require shop provided parts. There are a handful of shops that may work with you and install your customer supplied parts, although there usually will not be a warranty on these repairs or the parts.
Question 8:
How long will my repair take, and can I get an estimate on turnaround time?
The timeframe of the repair varies greatly from the point of diagnosis. Parts may need to be ordered, and the specific shop handling the repairs may have a specific timeframe that works best for your repair. Once the diagnosis is completed, and an estimate is revised, a clear and concise repair timeline should be able to be provided.
Question 9:
Do you offer loaner vehicles, shuttles, or pick-up/drop-off services while my vehicle is in for repair?
Most of the independent shops that operate within the Mechanical Triage framework do not usually offer loaner vehicles, shuttles, or pick-up services. If your vehicle is being services by one of our larger partnerships, and usually an insurance related claim, then there is a higher chance that those services could be provided by that shop independently.
Question 10:
What should I do if my check engine light comes on?
Call Mechanical Triage!! There is a quick check list of items a technician can go over with you on the phone to assess whether or not you possibly have an immediate need for service. However, the best option is to schedule a time and location best suited for you, to have an actual technician plug in a scanner and start the diagnosis process..
Question 11:
How often should I change my oil, and what type of oil do you recommend for my vehicle?
Your oil change intervals are usually set by the vehicle manufacturer for your specific vehicle. And mostly, the type of oil is usually recommended by them also. Every vehicle has its own specific viscosity requirements, that are specific to each engine.
Question 12:
What are the signs that my brakes need service or replacement?
The main indication that your brakes are leaning towards the end of their life is a faint squeeking sound when braking. If that starts to turn into a grinding or rubbing sound, then immediate service is usually a good idea. There are many other symptoms that could indicate brake system issues, so you may need a consultations to clarify this with a technician.
Question 13:
How do I know if my battery needs replacement?
Batteries usually only last 4-5 years. There should be a date sticker on the battery itself. If your battery is past this timeframe, it is wise to proactively replace the battery before it becomes an issue. Other signs that your battery is at the end of its life include hard or labored starts after the vehicle sits for numerous days, or labored starts on colder morning. If you are concerned about the condition of your battery, you may want to consider having the charging system, battery cables, and battery condition checked.
Question 14:
How often should I rotate my tires, and what are the benefits?
You should rotate tires every 5,000 to 7,500 miles, or about every other oil change, to ensure even tread wear, which extends tire life, improves traction, handling, fuel economy, and provides a smoother, safer, quieter ride, but always check your owner's manual for specific patterns and intervals for your vehicle.
Question 15:
What causes a car to overheat, and what should I do if it happens?
There are numerous components involved in the cooling system of an engine, that all need to work together to keep the engine safe. If the engine is overheating, it is highly advised to safely stop the engines operation as soon as possible, to ensure no further damage to the engine. You will most likely need a proper diagnosis to determine if a component has failed, or if there is a coolant leak.
Question 16:
Why is my car making a strange noise (e.g., rattling, squealing, knocking), and what should I do?
Vehicle noises can be concerning, but sometimes are not immediate concern for repair. While you should definitely consult the technician for a diagnosis, it is difficult to diagnosis here or over the phone what component is making the noise without further investigation.
Question 17:
When should I replace my timing belt, and what happens if it breaks?
Replace your timing belt according to the manufacturers recommend maintenance schedule. Most all modern engines are “interference” engines. If the belt brakes while operating, there is a very very high chance of internal engine damage that is usually not repairable and requires complete engine replacement.
Question 18:
How can I tell if my alternator is failing?
Signs of a failing alternator usually include the vehicle running very rough just prior to it shutting itself down. Followed by a no crank / no start condition. Jump starting may allow short term operation, but usually the vehicle will shut off again after minutes, as there is not enough power being provided to operate the ignition system. (If this happens in traffic, be very careful, as your battery will possibly be flat, and you may not have adequate voltage remaining to operate the emergency flashers)
Question 19:
What are common signs of transmission problems?
Transmission issues can range from mild and questionable, to absolutely apparent. Hard shifting, and slipping are usually tale-tale signs of transmisson issues, but with modern computer system taking sensor data from numerous components in the vehicle, it could be other issues causing what feel like a shifting or lag issue. If you have a feeling something isn’t right, you should consult a technician before the symptoms turn into a costly repair.
Question 20:
Is my AC not blowing cold air? What are the most common causes?
If your AC does not blow cold, the most common issue is low Freon levels. This would indicate a leak, and needs to be serviced by a certified shop. Other reasons vary from sensor issues not allowing the system to operate properly, to failed mechanical components in the system. Usually ac system issues need to be looked at and diagnosed by a qualified technician.
Question 21:
Why is my car pulling to one side while driving, and what could cause it?
There are numerous reasons why your vehicle is pulling to one side while driving. Everything from failing components, (including shocks, bushings, tie rods, ball joints) to air pressure, or alignment issues. It may also be a brake system issue. Regardless of the cause, the symptom warrants a technician to properly diagnose so that proper repairs can be made.
Question 22:
What does a pre-purchase inspection include, and how much does it cost?
Mechanical Triage offers a multi point inspection that includes everything from tire condition to seat belt operation. Top to bottom. Itemized with photo evidence, and a comprehensive repair plan for next step repairs. The cost of the inspection hovers around the $200 range. Other shops offer their own inspection reports and their own formats, but usually this is a standard practice.
Question 23:
How do I schedule a service appointment with Mechanical Triage?
There are multiple options for contacting Mechanical Triage for service requests. Once we have enough information (vehicle year, make, model, contact information, and diagnostic concerns) we can work together to find a time that you are available, and continue from there.
Question 24:
Are your technicians certified, and what experience do they have with heavy-duty trucks or fleets?
ASE certifications are very important in the automotive industry for certain shops. Some shops find it necessary to carry ASE certifications while some do not. This does NOT reflect on the quality of workmanship or expertise that a shop or their technicians have. Some shops have third party certifications direct from the manufacturers (factory trained service providers) and some smaller shops have technicians with other valuable skills that schooled technicians may not possess. Mechanical Triage is ASE certified. We also have experience with class 1-8 vehicles.
Question 25:
For fleet or commercial truck owners: What diesel-specific services do you offer (e.g., DPF cleaning, turbo repair, air brakes)?
Mechanical Triage offers diagnosis and component replacement on larger commercial vehicles. While some of the services can be provided on site, many of the services are best suited to go to specific shops, as they have more heavy duty and specialized equipment for repairs. Feel free to reach out to us with your specific questions so that we can help you find a solution..
Question 26:
Do you handle emissions testing or state inspections, and what do I need to bring?
We operate in Washington state currently. Washington state no longer has emissions testing. We do not provide state inspections, as that function is controlled by the WSP (Washington State Patrol). If you need to register an out of state vehicle, or schedule an inspection, we can help locate the closest WSP inspection center near you.
Question 27:
What is your process for providing repair estimates or quotes?
First, we would need specific vehicle information, like license plate number or vin number, so that we can accurately identify the year, make, model, and engine of the vehicle we are discussing. Then, we would need to perform a diagnosis, if the repair wasn’t a cut and dry situation, like a brake job, or a tune up, etc. We would then make a list of needed parts, and labor services, to be able to provide an accurate estimate in writing.
Question 28:
Are you insured, and what does your insurance cover for repairs or mobile service?
General Liability Insurance
Question 29:
What should I expect during a typical diagnostic visit with Mechanical Triage?
The technician will document your concerns, and take your initial symptoms into consideration, but will need to conduct their own diagnosis. This may include electronic scanning and data collecting, or road testing. While performing their diagnosis, there may be other components that may or may not be related to your initial concern that may be brought to your attention. A step by step plan will be outlined as to what needs to be repaired, and in which order. You can then work with the technician to take care of the most important repairs, or have everything brought back to good working order.
Question 30:
Do you offer roadside assistance (e.g., jump starts, tire changes, lockouts), and what is the cost?
Mechanical Triage offers third party assistance with these services. Depending on your current location, we will find the quickest option for you and get you up and running in no time.
Question 31:
For fleet customers: How do you handle preventive maintenance scheduling and tracking?
Preventative maintenance scheduling and tracking is sometimes a tricky animal to catch. With many companies having multiple drivers for multiple rigs, it’s sometimes difficult to keep up. We offer services that range from customer training to educate the drivers, to manually checking the mileage every week to stay on top of maintenance.
Question 32:
What are signs my truck’s DPF (Diesel Particulate Filter) needs cleaning or replacement?
Most all diesel engine systems will alert you of SCR Derate if you are past regen cycles. Once you get to 80% Derate, the DPF may need to be removed to be cleaned, or replaced.
Question 33:
How often should fleet trucks undergo DOT inspections, and what do they cover?
DOT fleet trucks undergo annual inspections. The inspections include, but are not limited to: brakes, lights, tires, steering, and emergency equipment. (Along side with driver compliance)
Question 34:
What are common air brake issues in heavy trucks, and how are they diagnosed?
Common issues include air leaks, under maintained slack adjustments, and air chambers that have leaking diaphragms. Diagnosis is fairly straight forward, and include brake tests, and measurements.
Question 35:
Why is my truck losing power or derating, and what are the first steps to check?
Most common Derate issues are DEF system issues, or DPF system issues. The first thing to check is the system codes, and live data to ensure the system is operating properly. Driving habits also contribute to clogged DPF systems.
Question 36:
What mobile services can you perform that don’t require a full shop (e.g., oil changes, brakes, batteries on-site)?
I have personally performed every single aspect of repair on site. From engine swaps and rebuilds, to axle swaps on F150 trucks. But the better answer is, that most shops are better suited for certain jobs, due to the equipment they have available to perform the job easier.
Question 37:
What are the advantages of choosing mobile repair over a traditional shop?
The highlighted advantages of mobile repair would include: Emergency services (if your vehicle was not mobile, but in a safe location, mobile services can save you TIME and MONEY, due to not needing a tow, and waiting for a repair shop). Ease of access (if you only have one vehicle, and no options for transport, then it’s difficult to get to a shop and leave your vehicle for the day). Other benefits include: Personalized service, flexible scheduling, and transparency..
Question 38:
Do you come to my home, office, or parking lot for repairs, and is there a travel fee?
Yes, we come to you. Travel fees are negotiable due to location to our standard service areas.
Question 39:
What equipment do you bring in your mobile service truck for on-site repairs?
The mobile service truck has a full setup of tools, that include: Jacks (and jack stands), Power tools (vacuum / welder / grinders), Daily use chemicals (penetrants / cleaners / sealants), Hand tools (all needed tools for multiple vehicle applications / including specialty tools), Electronic and manual diagnostic tools (computer diagnostic equipment / compression testers / electrical testing equipment / etc.). And also fluid management (oil containers and drain pans for fluid services)
Question 40:
Can you work on hybrid or electric vehicles (EVs), and what special precautions do you take?
Hybrid and Electric vehicles are a different animal, some systems (like brakes) are general enough that we can easily service them. But, with the addition of multiple computer systems and power management systems, it is best to refer you to one of our partnering service centers, that have more specialized equipment to properly diagnose and repair your vehicle.
Question 41:
How do I prepare my vehicle and location for a mobile service visit?
Flat ground, preferably concrete or asphalt. Other than that, the technician handling the repair should be able to navigate around most all other obstacles.
Question 42:
Do you provide detailed reports or photos of my vehicle’s condition after service?
Upon request, yes. The technician handling the repairs will take photos or videos as evidence of diagnosis, and repairs. These photos will be archived to a drive for future reference if needed.
Question 43:
What payment methods do you accept for mobile services (cash, card, digital)?
Most technicians can accept electronic payments of varying type, (for security reasons) but cash can be accepted. We have card readers and can also take checks (from returning customers only).
Question 44:
For classic cars or restorations: What experience do you have, and do you source rare parts?
For classic cars and restorations, we work directly with Dans Automotive. He is a high quality frame off restoration expert with decades of experience working on classic and rare vehicles. He has numerous outlets for sourcing and ordering hard to find parts. I have personally worked with him restoring numerous vehicles and restoring them to Concours ready condition.
Question 45:
What should I do if I’m experiencing a vibration or shaking while driving?
Vibrations and shaking usually derive from wheel or alignment issues. Either a balancing weight has left the tire, or the tire has damage and needs to be replaced. With a little more information, we should be able to diagnose the issue down and provide you with the correct service center to best address the issue quickly.
Question 46:
My car won’t start or has starting issues—what are the most common causes?
The most common causes of a no start condition, are a flat battery. (Accidentally leaving a light or accessory on, or poor battery condition). But this is parallel to battery terminal condition and connection issues. There are also additional issues like fuel delivery, or spark plug condition that can contribute to a no start or labored start condition.
Question 47:
How do I know if I need new tires, and what factors affect tire life?
Age is one of the most overlooked factors of tire life. Rubber gets hard and looses grip ability over time. Tires have wear bars to indicate end of life, but if the tire has a vibration at all speeds, or abnormal wear patterns, then a suspension / steering inspection should be conducted during tire replacement, and an alignment performed..
Question 48:
What are signs of suspension or strut problems?
Suspension and strut issues can present themselves in numerous ways. Tire wear is one. Clicking and groaning sounds when turning or traversing speed bumps is another. If there is ANY sound or vibration that your vehicle is making, that you find abnormal or concerning, you should definitely call Mechanical Triage for a consultation.
Question 49:
Why is my fuel economy dropping suddenly, and what should I check first?
Driver habits can contribute up to 10-20% of your fuel economy. But also, it may be time for a tuneup. There are numerous small aspects to engine management that can contribute to fuel economy, and with every vehicle and driving conditions, they are slightly different. However, if this drop in economy has occurred during a temperature drop, it is likely your tire pressure needs to be adjusted or the weather is changing the dynamics of your fueling on the engine. Start by checking your tire pressure as it can fall from 34 pounds to 28 simply due to temperature drops.
Question 50:
What are common causes of exhaust or smoke from my tailpipe (white, blue, black)?
Tail pipe smoke varies widely depending on the type of engine (gasoline or diesel) and the manufacturer. There are many components that play into smoke from the exhaust, like whether or not you are losing coolant in the cooling system, or oil…. If there is any noticeable smoke that is concerning you, it is time for a technician to conduct a diagnosis.
Question 51:
Why is my steering wheel vibrating, and is it safe to drive?
Safety is key. If it feels unsafe to drive, don’t risk it. Your vibration could be something as simple as a wheel weight that has fallen off the rim, or something more severe, like a failing suspension component or tire that could cause a serious safety hazard. Call for a consultation and schedule a diagnosis as soon as possible.
Question 52:
What causes dashboard warning lights (ABS, airbag, TPMS), and what should I do?
ABS, TPMS, and TRACTION CONTROL lights can associate themselves with each other, as they are all part of the same working system. A low tire can cause all of these lights, and systems to operate erratically. A wheel speed sensor can also cause some of these issues. A TPMS battery or communication issue can also cause these issues. Definitely time for a proper diagnosis with a scan tool. A technician can plug into the vehicle and determine what system and component is causing the issue, and plan for repairs. The AIRBAG light is its own system, and that light is usually on due to a communication issue with one of the components in its system. In the event of an accident, it is possible that the system may not operate properly, causing severe safety concerns. Please do not ignore warning lights and schedule a diagnosis as soon as possible.
Question 53:
How do I reset my check engine light after repairs, or does it clear automatically?
Your check engine light being active after a repair, is usually one of two things: either the technician forgot to properly clear the system, or you still have an ongoing issue. Check engine lights (for the most part) do not CLEAR themselves, and indicate an active issue that the computer is currently dealing with.
Question 54:
My car smells like burning or exhaust inside—what could it be?
The most common cause of burning smell inside the vehicle is fluid leaks on the exhaust manifolds. Mostly engine oil leaking from the valve covers. This will usually present itself while sitting at a stop light. You may have other or compounding concerns that need to be addressed, and this would warrant a diagnosis inspection by a technician..
Question 55:
What are signs of a failing water pump or cooling system leak?
The first sign of a cooling system leak is usually a heater or heat related issue during colder weather, but can present as overheating if air gets into the cooling system and closes the thermostat. If your vehicle is overheating, do not continue operating it, as this could potentially damage the engine. Definitely consult with a technician and schedule a diagnosis to confirm the issues and plan for a repair. (It is possible that you have anything from a loose hose clamp, to a failing radiator as well)..
Question 56:
Why are my headlights or lights dimming or flickering?
You may have multiple failing headlight components, but you could also have an electrical system issue, that may or may not include the charging system. This presents a safety hazard either way, and needs to be inspected as soon as possible.
Question 57:
What causes a whining or howling noise from the engine?
There are numerous moving parts in the engine system. Whining or howling noises can present themselves from any number of pulleys, be it an idler pulley, water pump, or alternator. Also, a vacuum leak issue or PCV issue can also make strange noises that resemble these sounds. If it’s concerning, it is time for a technician to perform a diagnosis to determine the issue.
Question 58:
How do I check my own tire pressure, and what PSI should I use?
On 99.9% of vehicles, there is a sticker inside the driver door that shows the appropriate tire size, and air pressure for the vehicle (regardless of aftermarket tire size) and this should be followed. General tire pressure for passenger vehicles usually ranges from 30 psi to 55 psi depending on size. Consult the sticker in the door. If there is no visible sticker, text Mechanical Triage, and provide some vehicle information and we will find a resource that includes valid tire pressure data.
Question 59:
What are signs my serpentine belt or tensioner is failing?
Belt and tensioner failure usually has a rattle or squeeking sound on startup, that may get quieter a few minutes into driving. But this could also be other components starting to fail. A visual inspection by a trained technician can answer this question quickly, as there are conditions that have visual ques a technician can explain to you simply.
Question 60:
Why is my power steering making noise or feeling stiff?
The most common power steering issue, is low fluid. Usually caused by old and failing hoses. When air gets into the system the pump makes a growling noise, and operates poorly. This not only causes a safety concern, but could also damage the pump and make repairs more expensive. Consult with a technician as soon as possible, to restore your steering system to working condition. (There could also be a seal inside the steering components that is leaking)
Question 61:
What are common reasons for a rough idle or engine misfire?
Mainly, a fuel / air ratio discrepancy seen by the computer. Anything from a failing coil, bad spark plug, vacuum line leak, fuel delivery issue, or mass air flow sensor reading can cause the computer to adjust its fueling, and cause rough operation. Because of the numerous systems involved, a computer scan with live data may need to be performed by a technician to determine the root cause of the issue.
Question 62:
Why do I have low or no heat from the heater in cold weather?
There are numerous reasons that your heating system may have issues. Ranging from low coolant, clogged heater core, open thermostat, failed heater blower motor, or blend air door operation issues. Because of the various amount of systems involved, it is wise to have a technician confirm what the issue is, and plan a course of repair.
Question 63:
What causes leaks under my car (oil, coolant, transmission fluid), and how do I identify them?
Oil is brown or black, transmission fluid is red. (Mostly). Unless your maintenance is overdue, and all fluids look black. Some power steering system use clear power steering fluid, some use transmission fluid. Coolants come in an array of colors (purple, blue, orange, red, yellow, green). The only real differentiation you might be able to make is, is it an oil, or a water based fluid. Either way, visual inspection during a diagnosis will allow the technician to determine where the fluid is coming from, and which component needs repair. (Water pump / hose / transmission pan gasket / etc..)
Question 64:
How often should I flush my transmission fluid or coolant?
With varying manufacturer requirements, you should follow their guidance. Service interval information is available online regarding fluid maintenance. You can also contact Mechanical Triage, and provide some vehicle details, and we can provide that information for you, specifically for your vehicle.
Question 65:
What are signs of a failing fuel pump, and is it safe to drive with these symptoms?
Failing fuel pumps can easily leave you stranded or in an unsafe situation, and can occur with little to no warning. Usually your vehicle will sputter as it dies, and have hard restart issues, or will restart and die again quickly. These symptoms are similar to other conditions (like electrical system failures) so it is advised to park in as safe of a location as possible and contact the technician to facilitate a diagnosis.
Question 66:
Why is my truck’s turbo making a rattling or whistling sound?
There are many components in a turbo system that can cause these symptoms. With newer turbos variable vane geometry, there are more moving parts. It could be anything from a failing bearing internally of the turbo, to a vacuum control issue for the turbo or waste gate operation. (Some tuned systems have a whine, but a rattle is cause for concern)
Question 67:
What maintenance does a heavy-duty truck’s air brake system require?
While slack adjusters are usually adequate for upkeep, visual inspections of engagement excursion rates, and line conditions should be carried out somewhat frequently. Visual inspections of brake shoe conditions and material thickness, and operational testing should be conducted at least monthly.
Question 68:
How do I know if my fleet truck needs an oil analysis or fluid testing?
If a condition or diagnosis is related to Degraded power, or noise, it may be time for fluid analysis. Also, for longevity of your engine, along with proper maintenance, you can have a fluid analysis done annually for recorded conditions of your equipment.
Question 69:
What are symptoms of a failing EGR valve in a diesel truck?
A failing ERG valve in a diesel truck may present itself through rough idling, poor acceleration, excessive black smoke, engine knocking, stalling, and a visible check engine light.
Question 70:
For mobile fleets: Can you service trucks at my warehouse or job site without downtime?
Aside from the time it takes to clear up the technicians schedule for your repairs, and the repair time itself (parts acquisition and labor times), YES the repairs can be conducted at your location, provided it is within the technicians service area.
Question 71:
What is your cancellation or rescheduling policy for appointments?
We understand that sometimes life happens. And you understand that when scheduled, we usually cannot resell your spot without proper notice. We ask you be considerate and provide over 24 hours notice for cancelations. Some partnering service providers have their own policies, and those terms will be relayed to you when scheduling an appointment, as a deposit may be needed for such an eventuality.
Question 72:
Do you offer discounts for seniors, military, fleets, or repeat customers?
Discounts may be provided by the third party service locations, and it is at their discretion on that matter. Most all service providers follow some kind of guidelines to make pricing more accessible to those individuals.
Question 73:
How do you handle customer complaints or issues after service?
Complaints will be looked into as immediately as possible. So that a resolution can be made. Please keep in mind, we are people, dealing with people, in an unperfected, unbalanced eco system. Issues due to service quality will be addressed by the provider, and if there is no possible way to resolve the issue, they may face penalties or be removed from the Mechanical Triage eco system.
Question 74:
Do you offer financing or payment plans for larger repairs?
There may be options for payment plans at the end user payment locations. Most repair facilities require payment upon completion, and you should plan as such when negotiating repairs.
Question 75:
Are your prices competitive with local shops, and do you provide price matching?
Every shop has slightly different pricing due to their experiences and expertise. We will strive to match you up with the most qualified repair facility per your diagnostic issues. The pricing market between shops is similar across the board, and pricing should not be the end all factor in choosing the proper repair shop for your needs.
Question 76:
What is Mechanical Triage’s policy on customer-supplied parts installation?
We do not install or warranty customer supplied parts. There are usually not a lot of locations that do. Independent non vested mechanics will usually perform those repairs for you, with your parts, but they most likely will not provide any type of warranty.
Question 77:
For insurance claims: Do you work with insurance companies, and what is the process?
We have access to many partnering service providers and shops that work very well along side insurance companies. With a few more details, and overall intention, we can help match you with a service shop that can help itemize and facilitate all of your repair needs.
Question 78:
Do you recycle old parts like batteries, tires, or fluids responsibly?
The EPA requires certain chemicals and fluids to be disposed of in a specific and responsible way. All of the shops in our roster adhere to industry standards when dealing with toxic and unsafe materials.
Question 79:
What should I do if my brakes are squeaking or grinding?
If your brakes are making any type of noises, you need to have a visual inspection done as soon as possible. The tire may need to be removed from the vehicle to confirm it is your braking system causing the issue, and a repair plan can then be generated.
Question 80:
How do you ensure technician quality and background checks for mobile services?
We require mobile technicians to have two years experience (minimum) in a shop environment, and pass ASE certifications. They also need to sign NDA agreements and NON COMPETE agreements to show loyalty and professionalism to the Mechanical Triage family.
