2017 Malibu: We are experiencing exhaust fumes getting into the cab of the car. Even when the vent adjustment is on interior circulation only. The fumes are more intense when stopped at a stop light and a car is in front of us. We took the car to our Dealer and they find nothing wrong. Can anyone help with a suggestion? ---

> [@J.07](#): > > Can anyone help with a suggestion? Stay a least two car lenght away from the car in front of you if possible. You could try a similar car and see if you smell exhaust fumes in the cabin.Could be a bad window or door seal…anything is possible. ---

If it’s actually a 2017, you should still be under warranty. I would take it to your dealership for diagnostics and repair. And I wouldn’t wait around on this repair, exhaust gasses contain carbon monoxide, which is a silent killer ---

Click around to find a battery operated CO monitor. Engine exhaust has a lot of CO in it so if you do have exhaust in the cabin this should start chirping like mad in about 15 minutes. Home CO monitors have a designed time delay in them. You may also be picking up oil that was spilled in the exhaust manifold,a little makes a big stink.

If that dealership cannot find anything, go to any other dealership. Your warranty is good at any Chevy dealership. Yosemite ---

Are the fumes only from other cars or do you get them when there are no other cars nearby? ---

My guy figured out the problem… the oil cap under the hood is not the proper size… I don’t know if it came from the factory this way or not… the oil cap is supposed to say dextros… I called a Chevy dealership ordered the part for 11.00 and I have not smelled the fumes in about two weeks now ---

Definitely… and I still haven’t smelled the fumes… I recommend everyone try that before going out spending an arm and a leg ---

odd that a 3 yr old car would have a replacement oil fill cap. i think the malibu has a turbo motor? you would think the emissions system would detect a poor sealing VC due to a leaky fill cap? maybe not
