#861 of 862 2008 4Runner Limited - Terrible sulfer smell by schten Aug 19, 2009 (8:31 pm)
I see from the previous post that this is not the first time Toyota has had a problem with their CC's. I bought a new (08) toyota 4runner Limited V8 in March with 13 miles, now has about 11K. She had her first oil change after 5000 miles (as recommended by the dealer) then a month or two later I noticed something strange. When I go from slow to fast at a moderate pace (passing cars, cruise control engaging on a hill, merging from off ramps onto highways, etc.) I get a foul stench inside my car that smells like a mix of ammonia and sulfur. For those who are really quick you put those together to equal pee and poopie. The smell is terribly strong at first then eventually goes away.....until I need to accelerate quickly again.    I have tried various scenarios like accelerating with the AC and the re-circulate on and accelerating with the AC on and the re-circulation off. I have also tried both previously mentioned methods with the AC off. Windows open, windows closed, you name it..I've tried it. I mentioned it to my mechanic before her recent 10,000 oil change, when I picked her up he said everything he checked the exhaust and everything was okay.   Has anyone had any luck having the dealers remedy this since the last post? I'm due for an inspection in September, if I point my mechanic in the right direction, he sees a problem, is there a chance it won't pass? If it does, I was planning on bringin the failure slip to the dealer. Any info would be greatly appreciated. Thanks!!

Replying to: des19554 (Mar 09, 2009 1:09 pm) I seem to remember reading my owners manual that it cautions against driving with the rear window open because of fumes entering the cabin. We have a 07 sport edition with V8 and have never noticed sulfur smell.   good luck with resolving the problem.
