4 times in 2 weeks my 2007 Jeep Compass just shut right down. No spitting and chugging and clunking. Just off! I think the first time I was just driving straight down the highway, NOT turning or hitting any potholes. But honestly I can't remember. The second I was driving out of a sort of bumpy business potholish driveway, 3rd, turning in reverse or maybe already shifted to drive (pulling out of parking spot) 4th don't remember. All times I turned it right back on and off I went. I saw this type of problem on a forum from back in 2010 and they thought the quick fix would be to turn the ESP off but now I'm seeing you can't ACTUALLY turn it off all the way. This is very dangerous though as it can shut off pulling out in traffic. When the mechanic put it on his computer tester thing NOTHING showed up.
