Flat Tire Parking Lot

What’s that strange car noise? Even if you’ve been driving for years, a strange noise can catch you off guard and cause worry — even more so if you’re planning a trip out from Chicago or LaGrange soon.

If you notice that your car is making a rattling, clunking, or squealing noise while you’re on the road, it could be a sign that your vehicle is in need of service. Don’t ignore these strange car noises; get your vehicle to The Autobarn Volkswagen of Countryside fast. Even once you know what’s making that sound — we diagnose your strange car noises below — you should still visit our service center for a checkup. 

What’s That Sound?

Is that a clunking sound when you hit the brakes?

A brake caliper could be damaged, or it could be missing entirely.

Hear a flapping under the hood?

A belt may be breaking down, or there could be something interfering with your fan.

A startling, loud bang?

Older drivers might be more familiar with this one: a backfire. Most commonly, this is caused by the catalytic converter not functioning properly.

Is there a squealing sound when applying brakes?

A squealing sound may mean your brake rotors are dirty, or it could mean it’s time for new brake pads. You can peek down there and look between your spokes to check — brake pads should typically be 1/4 inch thick.

Notice a high-pitched sound once the engine has been turned off?

Take a look at the radiator pressure cap. This sound could mean that a gasket is worn.

Does the transmission grind when shifting?

The clutch could be worn or just needs an adjustment.

Do you hear a popping in engine compartment?

There are several possible causes: an ignition problem, clogged fuel filter, worn spark plugs, or a compromised catalytic converter.

Does the engine squeal while accelerating?

Your drive belts are loose or slipping.

Do you hear a clicking noise that gets faster as you accelerate?

This could be your pistons sliding up and down, making noise because you’re in need of an oil change.
