Explanation
The exhaust system removes toxic gases produced by the engine. If it leaks, harmful gases like carbon monoxide (an odorless and potentially deadly gas) can enter the vehicle's cabin. This can lead to drowsiness, nausea, or even unconsciousness. If you suspect carbon monoxide exposure, stop the vehicle immediately, get fresh air, and seek emergency medical help. A leaking exhaust system is a serious hazard and should be repaired without delay. Have your exhaust system checked periodically to ensure it’s in good working condition.
