The defect: in affected vehicles, the EBCM software error may disable the electronic stability control and anti-lock braking system. If this error occurs, the vehicle’s ESC and ABS malfunction warning lights will no longer illuminate. Without functioning ABS or ESC warning lights, the vehicles will no longer comply with the Federal Motor Vehicle Safety Standard.
The hazards: according to the official National Highway Traffic Safety Administration filing, if the driver operates the vehicle while unaware that ESC and ABS are not functioning, there is an increased risk of a crash. ABS prevents the tires from locking up under heavy braking events and is an important part of a vehicle’s braking performance – especially in wet, snowy or slippery conditions. ESC helps the car maintain traction and is also important in wet or slippery conditions.
Affected components: EBCM, EBCM software, brakes, electronic stability control, hydraulics.
Affected vehicles: certain versions of the following vehicles are affected by the recall.
Number of affected vehicles: 463,995 vehicles are affected in the United States.
The fix: dealers will reprogram the EBCM free of charge.
