Service four wheel drive system comes up on my dash and then the traction light comes up on my dash and won't go out. When making a left turn or right sometimes the vehicle pulls. Also when accelerating and decelerating the rear differential makes a humming noise.
I pulled in to my brothers driveway there was snow on the ground. Put the car in park turned it off and exited the car. It started rolling forward so I jumped back in the car and put on the brake then moved it backwards a little and exited the car again. Again car in park and shut off. I walked in front of the car and found my brother. Asi was walking back to the car, it rolled forward again about 8 feet and hit my nephew's car sending it through the garage door. The next day I has the car towed to the dealership as I was afraid to drive it. Results from the dealer were nothing wrong. They told the the care had what's called and open differential and if the on wheel skidded the car would roll forward. I told them I had never heard of anything so absurd and their comment was that I needed to read the owner's manual and make sure I use the parking brake. I talked with the dealership owner and told him about it. He also told me that he had never heard of anything like this either. I asked that he talk with his sales people and have them tell their buyers anpbout this. I then talked with a customer service agent at Chrysler who told me she had never heard of such a thing. As a follow Chrysler sent a survey to me regarding their customer service . I recounted this situation and have heard nothing. I will never purchase another Jeep and if I could cancel the lease right now I would do so. This is very dangerous. I had been standing in front of my car just before it rolled forward. In addition, my car insurance premium was increased by $50 per month because of this accident?????? when I did nothing to create the problem. These vehicles should not be on the road with dangers like this. People could very easily be killed or very injured. I have told numerous people never to buy this car because of its danger.
