Summary

Customer Satisfaction Program. On certain vehicles equipped with Integrated Trailer Brake (RPO JL1), if the trailer battery is charged to a higher voltage than the vehicle battery, it may cause the voltage to feed back into the vehicle battery and create a false short to ground. This false short to ground will trigger trailer braking to be disabled with customer notification. Dealers are to replace the Trailer Brake Power Module (TBPM).

Owners of these vehicles have filed 78 complaints in the brakes category.
