While driving this morning (smart cruise control disabled by the weather), I set the cruise control and everything was working ok. I cancelled due to traffic and reengaged without issue. When I requested additional speed with the increase control, the car accelerated and continued to accelerate and did not stop accelerating until I hit the brakes and cancelled the cruise control. This is very unsafe. I expect this fixed and will contact the NHTSA and also file a complaint with them. This is dangerous and it is only due to my ability to quickly react did I avert an accident in snowy conditions! ***** I am checking the no crash button only because my quick action and response averted an accident, but this is very dangerous! *****
