Common Car Exhaust Problems

Posted on by admin

The health and overall performance of your car are dependent on the integrity of the exhaust system. When this system isn’t working correctly it can lead to several problems with your vehicle. In this blog post, we’re going to explore the most common car exhaust problems.


What are the most common car exhaust system problems?

  • Rust
  • Faulty oxygen sensor
  • Exhaust leaks
  • Clogged muffler
  • Broken hangers
  • Vibrations
  • Increased engine noise
  • Exhaust smoke



Rust is very dangerous for the exhaust system. If you’re frequently taking short trips and car journeys then this lets water collect in the exhaust system, but it never heats up enough to burn off. Over time this condensation builds up and turns into rust that corrodes your exhaust from the inside out.


Faulty oxygen sensor

Modern cars have several oxygen sensors and if it malfunctions or becomes faulty this can cause the engine’s computer to not be able to create a correctly balanced air-fuel mixture. This could lead to the vehicle being low on air and high on gas, creating a blend that’s hotter than intended. This can cause a clog in your catalytic converter.


Exhaust leaks

When driving on roads that have rough conditions regularly this can be difficult for vehicles to handle and cause an exhaust system to not last as long as it should. Driving in these conditions can lead to weak areas, such as causing joints to crack and leak poisonous fumes into the vehicle.


Clogged Muffler

One other car exhaust problem that arises from rough road conditions is a clogged muffler where small internal parts can become loose.


Broken hangers

The purpose of hangers is to protect your exhaust system from banging around when you hit a bump. When a hanger breaks or falls off this causes the exhaust pipes to loosen and move around. This loose movement can lead to dents, cracks, or in some cases, break off.
