problem first presented as cruise control would not set. called dealership to schedule repair. next day, main display screen showed several warnings to have multiple systems serviced. Systems included adaptive cruise control, driver assist, automatic collision prep, stabilitrack and brake assist. Called dealership to update them on these warnings. Delivered vehicle to dealership and they first advised that the only problem was the haptic seat motor. they stated that this device, which vibrates your seat to warn of impending danger, was tied to all other systems and those systems would all fail as a group. i was skeptical, but took what i could get. next day they called and stated that after they replaced not one but TWO haptic motors (one on each side of the seat), they still received error messages on the main display. further troubleshooting revealed that the brake assembly was binding at times and needed replaced. dealership replaced. returned my car. see next issue report for this ongoing saga.
