Four Mechanic Questions You Should Ask When Your Car Is in the Shop

Your mechanic knows your car, have you asked him about it?

Almost everyone at some point in their automotive ownership experience will visit their local auto repair shop. Whether you’re a DIY weekend warrior or you just occasionally check your tire pressure and oil levels, once the mechanic has a look at your car they will likely make recommendations. Just like any relationship, communications is key. You don’t have to be an expert to be informed but you do need to have a two-way conversation. Here are four mechanic questions you should always ask beyond the ever-essential “how much will it cost?”

1. Is My Car Safe to Drive?

Brake Pads

Though some car problems may merely be an annoyance, such as a faulty door lock actuator, there are other systems that are safety-critical, such as your brakes. Knowing whether your vehicle is safe to drive is important, especially if multiple components require attention. Just because a vehicle made it to the shop doesn’t mean it is safe to drive it home.

Your local NAPA AutoCare will know how to distinguish between repairs that are critical for your safety and those that can be delayed. For example, if you had to choose between replacing a faulty windshield wiper fluid line and a frayed serpentine belt, a mechanic would likely recommend the latter be attended to first and foremost. While your windshield wiper fluid is important for a clean windshield and visibility, it is far more important to keep the engine itself running. If the windshield wiper fluid doesn’t work you  can still clean it another way. If your serpentine belt shreds you may end up stuck on the side of the road.

2. How Long Can I Put Off the Repair?

Are you already riding in the danger zone, or do you have time before the issue becomes a real safety problem? Take your front brake pads, for example: Most brake pads come equipped with about 12 mm of friction material, and mechanics will recommend replacement with around 3 mm friction material remaining. Most vehicles have a brake friction material minimum thickness noted in the owner’s manual.

If your mechanic says you need new front brake pads, ask if they are metal-to-metal, or if you have a couple thousand miles to go. Your mechanic can help you decide if you need to spend the cash immediately or if you can postpone until a later date. If you choose to put off a repair, don’t wait too long. The problem isn’t going to magically fix itself. Ask the mechanic for an cost estimate and start planning for the repair. Knowing the cost ahead of time and how long the repair will take can help manage downtime and impact to your budget. Wait too long for a repair can turn a small repair into a major one involving more components than originally planned.

3. Could I Have Prevented This?

Repair frequency can depend on drivers’ habits. If you regularly run into brake problems like brake pulsation, for instance, you could be overbraking unknowingly. If you are a rideshare driver or delivery driver you may consume wear items (like brake pads and tires) faster than normal. Overloading a vehicle can also put undue stress on not just the suspension, but the brakes and drivetrain.

Barring mechanical problems, learning to brake gradually or avoid riding the clutch in a manual transmission vehicle could go a long way toward reducing your repair bills. Ask your mechanic to ride along with you on a test drive; he may be able to point out some changes you can make. Simple things like slowing down for corners or avoiding potholes when possible can make life easier on your car.

4. Is It Worth Repairing?

As cars get older, wear and tear can amass in unrelated systems and creep up on the owner. For example, it is well-known that Toyota engines last upwards of 500,000 miles with regular maintenance. Comparatively, shock absorbers and brake calipers, especially if you live in four-seasons regions, aren’t quite so long-lived. Your mechanic can help you decide whether it is worth it to make a certain repair. For owners of older vehicles, this could be the most important mechanic questions you ask.

Replacing front brake pads on a 500,000-mile Toyota Camry, which may cost about $200, might be considered money well spent. In contrast, unless the car is in near-mint condition, most mechanics would be reluctant to suggest a $2,500 transmission rebuild. Or if you live in the rust belt corrosion may lead to damage that simply can’t be repaired without drastic measures like welding. If your mechanic has a laundry list of items in need of repair, you should make peace with the fact that today’s repair won’t be the last.

In some cases parts availability can come into play. Vehicle manufacturers usually only make repair parts available to support vehicles for a certain number of years. After that it is up to the aftermarket to decide if a part is worth making. A common part that was cheap to buy 10 years ago may no longer be available, or if it can be found may command a premium.  This is especially true with high-end luxury vehicles where limited production combined with high-tech designs can quickly drive a repair into the thousands.

Now is the time to weight your options. You could simply be wasting time and money on a car that is less than or equal to the total repair costs. Calculate the total cost of repairs and compare that with a new or used car.
