Exhaust smell inside the car (Toyota Carmry 2007 SE V6) 1/4-1/2 mile after hard acceleration only on the freeway. Took the car into the service department and found no problems but it’s still happening. Does anyone with the same problem or experience?
Sorry, your question did not say it had being going on for 17000 miles.
You could try changing your cabin air filter to one that has activated charcoal in it which may get rid of the odor. I would have the complete exhaust system checked to make sure it is tight and that there are no leaks. Hope this helps
These replies are absurd. You should NEVER be able to smell exhaust in a closed cabin, no matter WHAT the system is doing. My 2013 Avalon has been back numerous times and it still does it after heavy acceleration - awful, acrid smell of burning sulfur. Exhaust system tests tight. Smoke test in pressurized cabin - nothing. I'm starting to hate the car.
