It used to be that there were relatively few things to look at when the check engine light came on or you were experiencing performance issues. Today’s vehicles are far more complex, so engine diagnostics are more involved. At TRC Automotive, we have the equipment and talent to ascertain what is going on with the engine of your foreign or domestic vehicle. Our experience with engine diagnostics enables us to move quickly through what is wrong to getting it resolved so you can be back to your errands in the Belmont, North Carolina area.

We recommend not necessarily waiting until you see a check engine light before having engine diagnostics run. There are several minor issues that won’t trigger the engine light. An annual checkup isn’t a bad idea so you can get ahead of any issues that could be affecting fuel mileage, performance, or could become a bigger issue. We also recommend having us perform engine diagnostics on a used car you are considering purchasing. The seller should allow this, but if they do not, that in itself is a good reason to walk away because it demonstrates that they know of an issue that they don’t want you to learn about.

Engine diagnostics are a valuable tool when combined with our experience in automotive services. Any repairs can be initiated with confidence that they are what is needed to get your vehicle working as it should. If you would like to know more about our services or would like to schedule engine diagnostics, don’t hesitate to reach out to us.

Winter is officially in the rearview mirror, but your vehicle might still be carrying the scars of "Pothole Season." Between freezing temperatures hardening your rubber components and those hidden craters in the asphalt, your suspension takes a beating on the roads in and around Belmont, NC from December to March. Ignoring suspension damage isn’t just about a bumpy ride; it’s a major safety risk and a silent killer of expensive tires . Here are the three red flags that suggest your car didn't make it through winter unscathed. 1. The "Cupped" Tire Tread Take a close look at your tires. Do you see uneven , scalloped dips in the tread ? This is called " cupping ." When your shocks or struts are worn out, they can’t keep the tire firmly pressed against the road. Instead, the tire literally bounces as you drive. Not only does this ruin your tires prematurely, but it also drastically reduces your traction during spring rainstorms. 2. The "Nose Dive" or "Body Roll" Does your car feel like a boat in choppy water? If the front of your vehicle " dives " toward the pavement when you hit the brakes, or if it leans excessively when turning corners, your suspension is no longer stabilizing the vehicle's weight. This shift in momentum increases your stopping distance, making it harder to avoid an accident in an emergency. 3. The "Stiff-Arm" Steering Wheel If you’re driving straight but your steering wheel is tilted to the side, or if you feel a constant " pull " to the left or right, a winter pothole likely knocked your alignment out of spec. This puts constant stress on your suspension joints and causes your tires to scrub against the road, wearing them down in a matter of weeks. Safety First: The Right Choice for Spring At TRC Automotive Repair , we believe your safety shouldn't be left to chance. Our ASE-certified mechanics use industry-leading Snap-on alignment equipment to diagnose exactly what winter did to your vehicle. Don't let a bad suspension compromise your safety or drain your wallet with unnecessary tire replacements. Make The Right Choice and schedule your Spring-Ready Alignment & Suspension Package today.
