While test driving, air conditioner did not work, I was assured that it would be fixed by time of pick up (July 11). The air worked when I picked up the vehicle, however, the check engine light was on. Air conditioning gave out 2 weeks later, took in for repair and they said the hose was cracked. When I picked it up after the air conditioner repairs, I didn't even leave the parking lot and the check engine light went on again. I have owned the car for 28 days and it has been in the shop for 10 days. Dealer does not want to make restitution.
2005 Jeep Wrangler x model had check engine light come on 20 days after purchase as a new vehicle. Also, overwhelming smell comparable to butane present inside the vehicle during longer drives and accelerating. Jeep was serviced 14mar05, light is off but smell still persists. Was told it could be coating on parts of engine or transmission burning off, but car is well outside of break-in period with about 2,000 miles on it. Dealership where serviced called to say the vehicle needed to be brought back several days later due to a code that came up on the diagnostics. Vehicle is currently being serviced again.
