RepairPal Expert Overview:
The brake system contains an actuator that adjusts the fluid pressure to the brake at each wheel. An electrical component inside the actuator may experience an increased electrical resistance resulting in the illumination of various warning lights, including those for the Vehicle Stability Control (VSC) system, Antilock Brake System (ABS), and Traction Control system. As a result, these systems may not function as expected, reducing directional control assistance and increasing the risk of a crash. Dealers will update the software for the Skid Control module to correct this concern.
