Finding a trustworthy repair shop: estimates, repair priorities and records

How to pick a shop, get written estimates, sort urgent repairs and keep records

You do not need to be a mechanic to keep a car safe. But you do need someone you trust when something goes wrong. A good shop explains what it finds, tells you what is urgent, and gives you a fair price. A bad experience can leave you paying for work you did not need, or putting off work you did.

Money is a real barrier to safety. A 2017 AAA survey found that 64 million American drivers, about 1 in 3, could not pay for an unexpected repair without going into debt. AAA put the average repair bill between $500 and $600 [1]. When money is tight, drivers delay brake jobs and tire replacements, and that is when maintenance becomes a safety issue.

This guide shows how to find a good shop, understand an estimate, set priorities and keep records that protect you.

What you can do yourself

Many basic checks need no tools or training:

  • Check tire pressure and tread
  • Check lights with a helper
  • Check oil and washer fluid, and top up washer fluid
  • Replace wiper blades and, on many cars, the cabin air filter
  • Look over belts and hoses for cracks and bulges
  • Check for recalls
  • Keep an emergency kit stocked

See our guide to the monthly car safety check. Leave brakes, steering, suspension, air bags, fluid service, sensor calibration and any high voltage work to a qualified technician.

Choosing a shop

The Federal Trade Commission suggests finding a shop before you need one, so you are not rushed into a choice [2].

Ask around. Friends, neighbors and coworkers with the same kind of car are a good start.

Check complaints. The FTC suggests checking with your state attorney general or local consumer protection office for complaints about a shop [2].

Look for certified technicians. ASE certification means a technician passed a test and has practical work experience. Certifications are valid for five years, then must be renewed with a new test [3]. The FTC notes that certifications are a good sign but do not guarantee honest or competent work [2].

Match the shop to your car. Some shops specialize in certain brands, hybrids, EVs or diesel engines. Ask if they work on your type of vehicle often.

Ask about warranties on repairs. A good shop stands behind its work. Ask how long the warranty lasts and what it covers, and get it in writing [2].

Start small. Try a new shop for an oil change or tire rotation first. See how they treat you before you need a big repair.

Describe the problem clearly

The more clearly you describe a problem, the faster and cheaper it is to find. Before you go in, write down:

  • What you notice: a noise, smell, vibration, leak or warning light
  • When it happens: starting, braking, turning, speeding up or over bumps
  • How long it has been happening and whether it is getting worse
  • Any recent repairs or events, such as hitting a pothole

Describe the symptoms, and let the shop diagnose the cause.

Get it in writing

The FTC recommends getting a written estimate that requires your approval before the shop goes over a set amount [2]. A good estimate lists:

  • The problem to be fixed
  • The parts needed, and whether they are new, used or rebuilt
  • The labor charge
  • The total cost and when the car will be ready

Some states go further. In California, for example, shops must give a written estimate before doing any work. If more work is needed, the shop must contact you, describe the work and cost, and get your permission before going ahead [4]. Your final invoice must list all parts and note any that are used or rebuilt [4]. Check with your state’s consumer protection office for the rules where you live.

Questions to ask before you approve work

  1. Can I have a written estimate that lists the problem, parts and labor?
  2. Will you call me for approval before doing anything that costs more?
  3. Is this a safety problem that needs fixing now, or can it wait? If it can wait, how long?
  4. What could happen if I wait?
  5. Can you show me the worn part, the measurement or the leak?
  6. Are you using new, rebuilt or used parts?
  7. What warranty comes with the repair, in writing?
  8. Can I have my old parts back?

Ask for your old parts before the work starts. California’s guide notes that you need to make the request before work begins [4]. The FTC also suggests asking for a repair order that lists the work, parts, costs and mileage [2].

If a shop recommends service more often than your owner’s manual calls for, ask why [2].

Set repair priorities when money is tight

Ask the shop to sort its findings in writing into three groups:

How to sort repair findings

PriorityExamplesWhat to do
Safety nowBrakes, tires, steering, suspension, lights, wipers, fuel or brake fluid leaks, any red warning lightFix before driving, or as soon as possible
SoonProblems that will get worse or cost more if ignored, such as a small oil leak or a weak batteryPlan and budget for it in the next few weeks
Can waitComfort and cosmetic itemsFix when you can

Fix the “safety now” list first. If you cannot afford a safety repair right away, ask whether the car is safe to drive at all until then, and get the answer in writing.

AAA suggests other ways to manage costs: get a second opinion on the diagnosis, and ask about discounts or payment plans [1]. AAA also urges drivers to save at least $50 a month for car repairs, and to follow the maker’s service schedule to avoid bigger problems [1].

Your warranty and independent shops

You do not have to use a dealer for routine maintenance to keep your new car warranty. The FTC explains that under federal warranty law, a maker cannot void your warranty just because an independent shop or you did the work [5]. Coverage can be denied for damage caused by faulty work or parts, but the maker must show that was the cause [5]. Keep receipts for everything [5].

Service contracts and warranty scams

An auto service contract, often sold as an “extended warranty,” is a contract to pay for some repairs. The FTC says it is not a warranty under federal law [6].

Be wary of calls, texts or letters warning that your car warranty is about to expire. The FTC says these companies probably have nothing to do with your dealer or carmaker. If you respond, you may be pressured to give financial information and a down payment before you see the contract’s details [6].

Before buying any service contract, the FTC suggests [6]:

  • Check what your current warranty already covers, so you do not pay twice
  • Compare the cost with what repairs are likely to cost
  • Ask about deductibles for each repair
  • Read the exclusions, including any limits on where you can get service
  • Research the company, since some go out of business before you need them

Keep a service log

Records help you stay on schedule, prove maintenance for your warranty and raise resale value. One Lexus guide says each record should list the date, the mileage and the work or parts [7].

June 143,800Wiper blades, cabin filterBlades and filterDid it myself, cost of partsBlades in 6 to 12 months

Also keep:

  • Repair orders and receipts
  • Recall completion paperwork
  • Sensor calibration reports after glass or body work
  • Tire purchase records and registration
  • Your monthly check notes

A folder in the glove box and photos on your phone both work. Pass the records on when you sell the car.

If a repair goes wrong

  1. Talk to the shop manager or owner first. Bring your paperwork.
  2. Put your complaint in writing if that does not solve it. Keep copies.
  3. Contact your state attorney general or consumer protection office [2]. In California, you can file a complaint with the Bureau of Automotive Repair [4].
  4. Consider small claims court. You usually do not need a lawyer there [2].

Be ready for the roadside

Even well kept cars break down. Keep these in your car [8, 9]:

Check whether you already have roadside assistance through your insurer, an auto club, your carmaker or a credit card. Save the number in your phone. If you break down on a busy road, see our guide on breaking down in a live lane.

Frequently asked questions

Should I go to a dealer or an independent shop?

Either can be a good choice. Dealers handle recall and warranty work for your brand. Independent shops are often less expensive. Pick a shop with good reviews, certified technicians and written warranties on repairs.

How do I know if a repair is really needed?

Ask the shop to show you the worn part, the measurement or the leak, and to explain what could happen if you wait. For big jobs, get a second opinion [1].

Is an extended warranty worth it?

It depends on the price, what it covers and your car’s reliability. The FTC suggests checking your existing warranty first and reading the exclusions closely [6]. Never buy one from an unexpected call.

What if I cannot afford a safety repair right now?

Ask whether the car is safe to drive until you can fix it, and get that answer in writing. Ask about payment plans [1]. If the shop says the car is unsafe, do not drive it.
