Can't get out of park BAS,ESP,lights come on
i am having the same issue. everything comes out with no malfunction until i step on the brake then esp and bas comes on. it goes away when i turn off the car.
ABS and BAS lights on constantly, car stuck in park due to failed brake light switch. $22 for part at dealer.
oops, answered with wrong reply last time. Brake light switch came on usually after heavy moisture. Replaced but still comes on from time to time.
Got BAS and ESP lights after brake was depressed after initial start up. Would extinguish only temporarily when car was turned off and turned back on however caution lights immediately return once brake pedal is depressed.
