My cruise control unit will not engage. And I have (6) six warning lamps showing every time I operate the car. With these lamps showing on the info system screen, the cruise control will not engage! I asked the dealership about it. And was told that the wheel bearing unit has moved away from where it is bolted on. And now it is touching the air bag control module. That's why I've got six lamps showing up on the center info screen, every time I operate the car. And on another incident. I was traveling on the interstate and their was some water that had collected in a dip between hills. And when I traveled through it, the force of the water flowing into the engine department, knocked the cruise control off. Disengaged it. I'm am available for inspection of said vehicle. Oh yes, this happened once before, but all of a sudden all the warnings lamps turned off. But I'm not so lucky now. It doesn't seem to affect the air bags any, but I could be wrong! the dealer explained what has happened within the components of my problem. But, since I wasn't forth coming to pay them to check or repair it, nothing got done. And it has been going on for about 6 - 8 months.
