What to Do If Your Car Is Making Strange Noises

Some noises mean pull over this instant. Others just mean "get it looked at sometime this week." Telling them apart mostly comes down to what the noise sounds like and when it happens.

1. Grinding when you brake

   Stop as soon as it's safe. That usually means the pads are worn through, and full brake failure could be close behind.

2. Squealing through turns

   Often power steering fluid or a worn belt. Not usually urgent, but don't let it go unchecked for long.

3. A loud bang or backfire

   Points to the exhaust or fuel system. Get it looked at before you put on many more miles.

4. A thump that speeds up with your speed

   That's a tire or wheel issue most of the time. Inspect the tires before continuing.

5. Knocking from under the hood

   Serious, full stop. Get it towed rather than risk the engine over it.

6. Not sure what you're hearing? Don't guess

   Describe it to dispatch or a mechanic, including when it happens. They can tell you whether it's tow-now or drive-carefully.
