Braking system warning lights - on four different occasions, the brake system warning lights have come on requiring that I pull the vehicle off the road and shut the ignition off to reset the lights. Error codes in the computer have resulted in replacement of brake booster / master cylinder assembly replacement, brake fluid sensor check, brake pedal switch adjustment. Braking on this vehicle is inconsistant with overall concerns regarding brake system performance.
