This morning I activated my cruise control (cc)as I normally would at 55 mph. Immediately my truck began accelerating until I finally disengaged cc when the speed reached 83-85 mph. It was still accelerating at the time I disengaged it. I attempted to recreate the incident with no luck. Before the incident, I was driving in a city environment at speeds less than 55 mph, so there was no way I had previously set the cc to a high speed that would have caused this to happen had I hit resume.
System will occasionally suddenly decelerate as I am passing, usually a large truck. I will be in adaptive cruise control and as I get abreast of the trailer, the vehicle will suddenly decrease speed by 10-20 mph, then accelerate back to the set speed. This, obviously, has the potential to create a rear end collision if someone is following and not paying full attention, esp if there are multiple cars following. This has happened multiple times.
While driving the vehicle the steering wheel pulled to the left and the steering wheel turned to the left considerably and permanently even when it was going straight on the road, the vehicle was taken into service, they aligned it and in just 500 miles it began to pull to the right and the steering wheel was turned to the left again even when the vehicle was going straight on the road. I have an appointment in service again soon.
