NHTSA complaint #11310887, filed 2020-02, 34,800 miles“Vehicle stationary in car wash and while manually using handheld at front of vehicle towards vehicle grill, back of vehicle opened/lifted. Has now happened multiple times and dealer has made no repair, but disconnected exterior sensor at gate (where you kick under vehicle to release gate for lift/open) in effort to eliminate that if instance recurs. Concern is for safety if driving in rain and back opens/lifts while operating on highways/roads. Owner is former sheriff's deputy kn kankakee county.”
NHTSA complaint #11267719, filed 2019-10, 5,000 miles“We received an alert/warning that is nearly constantly beeping and servicing the trailer brake system. We have never used the wiring or towed anything, and the trailer brake system is unused. The beeping is near constant, even after we “dismiss” the alert and is very distracting when driving.”
NHTSA complaint #11635425, filed 2025-01“Received a message on driver information system that states service trailer brake system. When towing a trailer, the trailer brakes are inoperable and pose a safety risk in the event of a sudden brake event. GM apparently has a service bulletin published for this message which indicated a replacement of the connector in the wire harness should be performed. Although I don't tow trailers often, I should be able to rely on this feature in my vehicle. My vehicle only has 70,000 miles and this is too soon for such a part to become faulty.”
NHTSA complaint #11464220, filed 2022-05“The contact owns a 2019 GMC Yukon. The contact stated that while driving at an undisclosed speed, the service trailer brake system warning light illuminated and alerted the contact. The contact stated that there was no trailer brake. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and the contact was advised to take the vehicle to the dealer. The failure mileage was approximately 13,000. The VIN was unavailable.”
