As I was driving on the freeway my car which was on cruise control. The car went from 60-50-40-30 within 30 seconds while it still said cruise control was on and the gas and brakes didnt work. I had to pull over to the side of the road. The electronics still work but the car no longer work and did not turn on. It seized while I was driving. No warning lights, no check engine light, no gas light, absolutely no warning before the car seized.
The dealer refused to perform warranty work when the check engine light came on unless I agreed to pay a fee of approximately $125 if the dealer decided that the work was not covered by the warranty.
