What the reports in each category say, in the owners' own words
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
I was turning out of my neighborhood and as I accelerated to merge with traffic my car started jerking. My dashboard “D” symbol only started flashing on and off and then my transmission service required light came on, (just had it done 8/25 and it is 11/25) and the BSW service required light came on as well. As I continued down the street everytime I pressed on the gas pedal the car kept jerking backwards and forward.
Driving home with no other cars around the forward collision warning goes off for no reason losing power and slowing down on it's own. This has been an ongoing situation since the car was new, I've made numerous attempts to have my local dealership look into this situation and all they tell me is to take video when it happens.
