With cruise control activated and engaged at 65 mph, vehicle accelerated on its own up to 80 mph befoe I stepped on the brakes and disengaged the cruise. When I re-engaged the cruise the vehicle immediately accelerated at full throttle until I stepped on the brakes. I repeated this 5 times over the next 3 hours. Then the behavior changed. Now when I activate the cruise the "cruise" indication illuminates on the dash as it should but when I activate the cruise with the "set" button the car does not change speed or begin to cruise. Instead the "cruise" indication on the dash goes out.
I have no codes from the ODBII
Has anyone had the same problem and gotten it fixed? What was the cause please? Thanks, Mike
