Adaptive cruise control problems by model year
What owners say
clockspring malfunction causing horn, cruise control, and air bag not functioning
My acc sensor will not connect therefore my cruise control does not work, leaving useless buttons on my steering wheel. We have no idea what is wrong with the whole system. Took it to the dealership and while they were doing recall work, they checked it. Said I would have to buy the $2,000+ acc unit and then it would probably be $1,000+ labor and then however much if they have to replace wires or anything else. I just want my cruise to work, I don't care if the distance part works. Warranty would not cover it and I'm sure I no longer have any factory warranty left on my vehicle.
1. Jeep dies for no reason when decelerating it happens at highway speeds when taking the foot of the gas it last happened on highway 1 on a big curve, steering and brakes lost power on a cliff side road.(scared me and the family 1/2 to death) it has happened on the dumbarton bridge in commute traffic it also happens when decelerating on off ramps or coasting to stop lights. You need to completely stop the car put it in park and press on the brake to restart it. This in traffic is also dangerous jeep says 10 things may cause it and they will not fix try any of then because they cannot pinpoint which one it is. 2. Cruise control slams on the breaks for no reason. Another dangerous problem no cars in front of me, open highway, no overhead bridges or guard rails in sight and the brakes slam on.
I have 4 recurring problems with my jeep. First, the driver's heated seats periodically will not work. Second, upon starting my car, it will just stall or shut down. This happens 2 to 3 times a week. Third, the check engine light continuously comes on and off (and when I get it checked, I am told something about the thermostat, but have had no problems with it overheating). Finally, the cruise control on/off button will not work sometimes. I have to physically hit the steering wheel for it to work. I have read about tons of recalls for my year jeep, but my VIN number is not included. I am starting to think it should be.
Yesterday, 5 jan 12, as I approached a stop light I removed my foot from the gas and applied the brakes. The vehicle did not slow down as expected. It was as if the engine was fighting me. I put the car into neutral and the rpms shot up to about 5000 and then went back down. The cruise control was not engaged and my foot was on the brake, not on the gas. Today, as I was coasting towards an intersection, foot off the gas, I stepped on the brake and again the engine revved up causing me to have to press very hard on the brake to stop. After no more than one or two seconds the problem disappeared. This could easily cause a serious accident.
