NHTSA Complaint #11555866 — 2015 CHEVROLET TAHOE

On Wednesday, 11/15/23, I was sitting in my vehicle while it was parked and running for several minutes. After a few minutes, the alert chime went off and the message "Service Trailer Brake System" was displayed on the dash notifications. This alert persisted for several minutes. Since this initial incident, the same alert has displayed 3 or 4 more times, but while driving. It repeats persistently, causing a major distraction, blocking my speedometer, and disabling bluetooth features. I nearly wrecked because of the distraction and have not been able to tow my trailer because of the risk of of the trailer brakes not working. I have an appointment scheduled with my mechanic on 11/28/23 to get this repaired, but have recently learned of several incidents of this same alert from other GM vehicle owners. This seems to be a defective wire harness and needs to be recalled as it is unsafe and renders the vehicle useless for many intended purposes.
