The car was purchased on 8/15/2026. On November 6th 2026 with 3051 miles on all the gauges, electronic dashboard, gps , climate controls, heads up display failed while car was in driving. There was no way to tell what speed the car was going, the gas level, rpms, engine temperature, etc. Navigation failed, Cruise control failed, I was unsure if the emergency braking system failed. The dealership responded there was over 27 error codes on the car computer. There was no way of knowing if the signal lights were working. There was no prior warning to this failure. The GMC service department at the dealership confirmed the failure and said it needed to replace the radio control module. It took 70 calendar days for a replacement module to be provided, and a new software patch was uploaded after several attempts. After the vehicle was repaired the dealership acknowledged that they have been seeing this problem. GM has failed to provide any other assistance.

The infotainment and instrumentation cluster will reboot while driving. This has happened multiple times while on the express way and while using super cruise. When the event happens the infotainment and instrument cluster will turn black for multiple minutes rebooting. At times they do not successfully reboot and forces the vehicle to pull over stop and force a system reset.

Vehicle Status: Brand New Current Mileage: Approximately 10,000 miles Incident Description On 1/8/26, while operating the vehicle on the interstate at highway speeds with cruise control engaged, the Check Engine light began to flash. Simultaneously, the vehicle’s warning system issued an alert stating that the engine oil was excessively hot. Immediately after these warnings, the engine began to emit a loud knocking sound and lost all power, shutting off completely while in motion. I was able to safely maneuver the vehicle to the shoulder of the road. Post-Failure Observations Upon inspection under the hood, I noted the engine was radiating extreme heat. I allowed the engine to cool completely before attempting a restart. While the engine attempted to turn over, it failed to start. Diagnostic Alerts Following the mechanical failure, I received multiple critical notifications via the GMC mobile app citing various engine failure errors. Summary Given that this vehicle is brand new with only 10,000 miles, a catastrophic engine failure of this nature is unacceptable. The vehicle was being operated under normal highway conditions when it became inoperable, posing a significant safety risk. I am seeking a full diagnostic review and a permanent resolution under the manufacturer's warranty.

Roughly one to two times per day, a notification pops up on the infotainment screen stating that the brakes need to be serviced due to the brake assist system failing. The vehicle has been brought to 3 different dealerships and none of them know what the problem is, how to fix it, or whether it is safe to drive the vehicle still. The brakes seem to be working fine, however, it is concerning that even if the notification is safe to ignore, the brakes could indeed end up failing and the driver may not be aware due to receiving frequent brake failure notifications per day.
