Exhaust Noises
Rattles, roars, and hissing from underneath or behind the car. Exhaust problems are usually easy to spot by ear.
Exhaust noises are usually easy to spot because they come from underneath or behind the car. A healthy exhaust system should be relatively quiet. If you hear rumbling, rattling, or hissing, it could mean a component has come loose, corroded through, or developed a leak. While exhaust issues are not always urgent, a leaking exhaust can allow harmful gases into the cabin, so they should be investigated.
