Cruise Control problems of the 2012 Jeep Grand Cherokee

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.

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.
