Consumer Description

I have been receiving the “Service Trailer Brake System” error intermittently. The only information I have been have to find around this is a defective wiring harnesses between two modules. This defect is not due to wear/tear and has been reported as a defective part on multiple GMC models. When this service error pops up it is distracting and very unsafe for driving as well as dangerous when towing as the driver has no idea of the trailer brake system is functioning properly..
