Why is My Car Making Strange Noises?

Do you hear strange noises coming from your car, truck or SUV? Do they happen right when you turn on the engine or only when you are driving? Do they get louder when you make sharp turns?

These are all good questions to ask when it comes to identifying the source of an unusual or unpleasant sound coming from your vehicle. Almost any bad component can lead to an audible clue that something isn't right. However, there are some common culprits that you can look out for. 

Either way, any strange sound is worth getting inspected by a professional mechanic like the technicians at Simard Automotive in Fairbanks, AK. We can identify the specific problem and recommend the necessary repairs. Here are some of the most common sources of unusual vehicle noises:

Exhaust System

Vibrating and rattling noises are often associated with an exhaust system issue such as a failing catalytic converter. Or, if the car is running unusually loud, there could be an exhaust leak or a muffler problem.

Timing Belts and Fan Belts

There are various belt systems under the hood to control fans and engine timing components. These rubber belts can become loose or frayed, and that will typically lead to some loud whining or squealing noises.

Wheels, Brakes and Suspension System

Vibrating and humming noises may happen if the wheels are out of alignment, if tire treads are low, if the suspension is having problems or if there is a worn wheel hub bearing. Screeching and squealing noises while you drive or when you come to a stop are generally coming from the brakes. It may be time to replace the brake pads or get a full brake service.


The engine itself could result in some unpleasant noises, or rattling/vibrations might also be a sign that one of your engine mounts is loose or weakening. If you believe the sound is coming from your engine, do not wait to have your vehicle looked at by an automotive expert.


Clunking and grinding noises (especially as the car shifts between gears) could be coming from the transmission, clutch or torque converter. Again, transmission problems are no joke, so you will want to have your vehicle inspected as soon as possible.
