Cruise Control problems of the 2008 Chrysler Aspen

Suddenly acceleration. This has happen 4 times while braking. Major damage was sustained to the vehicle when it was involved in a collision. Do not remember if the cruise control was during the times the sudden acceleration was experienced. Was going around 5 ã‚ 10 mph stepped on brake to stop and engine revã‚ed up and before I was ale to turn key off or put the transmission in neutral I hit a camper. The first time this happened I was on an isolated road and was able to stop the car without incident. I call the Chrysler dealer and was told there was nothing that they could check that would verify my complaint. Another time was on highway and applied the brakes and tach went to approx. 4000 rpm. Again I was able to put off the road safely.
