: the contact stated when cresting a hill the cruise control will over accelerate by 3 to 4 mph. The momentum causes the accelerator to disengage, when it re -engages the vehicle accelerates as much as 15 mph more than the set speed. The hill does not have to have a decline for the acceleration. The owner's manual states this could happen and the brake should be applied after cresting the hill. The dealership was able to duplicate the problem and determined it is an anomaly in the programming of the computer. Other model year vehicles were driven and the dealership determined it happened with those vehicles. The brakes slow the vehicle sometimes, but the cruise control must be deactivated to completely remedy the problem. Updated 02/07/06.

Re: NHTSA action number : PE05065 brake light switch was replaced on my 2005 Chevy Colorado after I reported, to the dealership, that none of the brake lights worked and the cruise control would not activate.

2005 Chevrolet Colorado - cruise control stopped working. - my son has the same vehicle as me and had the same problem. He said the service person at dealership told him his brake lights were out as well. - we checked my brake lights and they were not working as well. - there were no lights on the dash to indicate the brake lights were out.
