I have a 2007 Jeep Grand Cherokee diesel. Bought new, Nov. 07. At about 28k miles, on may 24, noxious fumes started coming through the a/c vents while idling, after coming to a stop. Took to dealer. They had it for 3 days, got a run around, they said Chrysler tech line said it was normal, told me to set the a/c system on recirculation. Service manager admits he smelled it but they couldn't find the problem. Called Chrysler tech line, they said the same thing also that I should take it to a dealer with better technicians. Problem is getting worse, stinks, causes eye sting. Probably exhaust fumes, smells like a natural gas leak only worse!.
