Your RV’s exhaust system may not be something you think about often, but it plays a vital role in keeping your vehicle running safely, efficiently, and cleanly. A healthy exhaust system helps reduce emissions, protects your engine, and maintains fuel economy.
At Ernie’s Inc. in Olympia, we know just how important it is to keep your RV in road-ready condition—and that includes the parts you don’t always see. If your exhaust system starts to fail, it can lead to poor performance, unwanted noise, and even dangerous fumes inside your RV.
Here are the top five signs your RV’s exhaust system might need some professional attention.
1. Loud or Unusual Noises
Has your RV started to rumble louder than usual? A failing muffler or a leak in your exhaust system can cause sudden changes in sound. If you notice rattling, hissing, or a deep growl that wasn’t there before, it’s time to get it checked out.
At Ernie’s, we have the trained eyes and ears to pinpoint where that noise is coming from—and fix it before it leads to bigger problems.
2. Decreased Fuel Efficiency
If your RV suddenly seems to be burning through more fuel than usual, your exhaust system could be the culprit. A leak or blockage can throw off your engine’s performance, causing it to work harder and burn more fuel.
You shouldn’t have to worry about getting fewer miles per gallon on your summer travels. Let our team take a closer look and get your system running efficiently again.
3. A Persistent Smell of Exhaust or Gas
This one is serious. If you notice a strong odor of exhaust or gas either inside or around your RV, it could indicate an exhaust leak—and that can be dangerous. Carbon monoxide is a colorless, odorless gas that can pose real health risks if it enters your cabin.
When in doubt, don’t wait. Bring your RV to Ernie’s, where we’ll run a full inspection to make sure you’re safe on the road.
4. Vibrations While Driving or Idling
Does your RV feel like it’s vibrating more than usual when you’re idling or cruising? An issue in the exhaust system—such as a broken pipe or loose mount—can cause your rig to shake or rattle.
Our team knows RVs inside and out. We’ll track down the root of the problem and restore that smooth, steady ride you’re used to.
5. Check Engine Light is On
Sometimes, your RV knows something’s wrong before you do. A faulty exhaust system can trigger your check engine light, especially if there's a problem with the oxygen sensor or emissions control system.
At Ernie’s, we use advanced diagnostic tools specific to RVs to quickly identify and resolve the issue—saving you time, stress, and guesswork.
