Power Loss

As your car ages, it will slowly lose power. This slow change over time is normal and shouldn’t send up any red flags. If, however, you notice a sudden loss of power, you should have your vehicle inspected immediately. Major component failures can result in a quick power loss. This symptom is often also accompanied by problems in the vehicle’s movement like jerking, lurching, stalling, or surging. If your car shows these signs, take it to your mechanic right away. If you are a good distance from your repair shop, you may want to consider having the car towed to avoid any further damage, which may be costly.

Unusual Sounds

The sounds an engine makes tell us a lot about how it is running. If you hear loud, difficult-to-ignore noises, they are probably worth investigating. One problem indicated by noise is a bearing failure. If you hear a loud sound coming from the bottom of the engine, this problem is most likely occurring at the crankshaft or the piston wrist pins. Internal engine trouble is signaled by a knocking sound.

Most noises that indicate engine trouble get louder when the engine is strained more, for example when you accelerate or climb a hill. If you suspect a problem, don’t put your engine under any more stress than necessary. Get it checked out by one of our certified mechanics, and you'll save yourself time and money in the long run.


If your car is smoking, it’s likely that there’s a problem in your engine. The form and color of the smoke helps us make a diagnosis. To best identify the issue with your engine, bring your vehicle in to one of our Express Oil Change & Tire Engineers locations and have one of our certified mechanics properly inspect the vehicle.
