Nothing can make your heart race faster than hearing an out-of-place noise coming from your car. Sounds are definitely indicative of a problem, and they should be addressed as soon as possible to keep you and others safe and to help you save money!

A ticking sound could be low engine oil.
Low on oil or damage to the engine
Brakes or something under the hood.
Wheel bearing.
No matter what the noise is or where it's coming from, you should have it inspected sooner rather than later. The earlier you address a problem, the better because if an issue goes unrepaired, it can turn into a bigger, more expensive, and potentially dangerous problem!
