“The cruise control does not work going down a hill. It works on a level road. It works going up a hill. I set it at say 50 MPH on us route 30, boswell, pa going down a hill and without applying the brakes the vehicle would be going 60 MPH at the bottom of the hill. This is dangerous. Dealer told me not to use the cruise control going down a hill!”
