A car exhaust leak is dangerous. Aside from operational issues, it also creates a major safety hazard by releasing toxic and odorless fumes into the cabin. Do not hesitate to bring your vehicle to an auto service if you suspect a leak.
3 Signs of a Car Exhaust Leak
Lower MPG
A leak causes engine pressure fluctuation. This affects the oxygen sensor and in turn may decrease the total MPG by two to three miles.
Louder Engine Noise
Does the vehicle sound louder than usual when you accelerate? The increased engine roar may sound nice, but it’s having a negative effect. This is likely an indication of a leak near the exhaust manifold.
Vibrations
Do you feel a vibration in the steering wheel or pedal? A leak causes the escaped gas to enter into the steering mechanism, causing a light but noticeable vibration.
Consequences of a Leaky Exhaust
Noxious fumes like nitrogen oxide and carbon monoxide can enter the cabin causing dizziness, headaches, nausea, and fatigue. In extreme cases, the poisoning can lead to death. This was tragically the case in 2014 when two Pennsylvanian teens died after an undetected exhaust leak caused carbon monoxide to enter the enclosed cabin.
In addition to the dangers, a leak can also be harmful for the car by causing engine backfiring. Escaped fumes that mix with the air creates backpressure, resulting in a backfire that reduces engine performance and hurts fuel economy.
