Sometimes when I start it the trac off, abs and brake warning lights stay on. When that happens the climate control (no heat or air), heated seats, and the overhead computer don't work. This may happen several times in one day then not do it for a few weeks. Every time I've tried to take it in it starts working before we get it in. Of course it acts up when it's very hot out (no air) or when it's very cold (no heat). The dealer is no help. I've had several other problems and everytime a new thing happens I tell my wife to remind me to never buy Chrysler again.
