i took it to the shop three times and they couldn't find anything, they didn't smell it...well on a trip to ocean city Maryland I kept the a/c off until it got to hot...once I hit the button we had to pull over...even the dog wanted out of the car...it's smell like a dead animal sometime..in the winter we even had to drive with the windows down, the temp was 20 that day...the main place at jeep said that we could take it back to the dealership again, but they will not find anything...I started to think I was crazy until I look up on googles and type in 2015 jeep smells...I was glad to find out that we are not the only ones with this problem..a couple drove theirs for about 2 hours and then the smell hit them making them sick...another couple can not pack in the garage because the smell comes up into the house...we love the jeep and I was thinking about buying another so we both would have new cars...she is retired, and I have retired twice once in the navy for 20 years...this is sad..we love to travel...but now we have a jeep that you are afraid to drive...
