OnStar Telemetry Control module suddenly failed. Systems such as automatic crash detection, directions, mapping and OnStar emergency connection and SOS all not working. Rests did not work and truck is at the dealership for repairs. Internet reports that this is a common issue with 24-25 models but GMC not proactively repairing or compensating owners for repair. They issued a service bulletin for some models but are resisting a recall to address safety issues. GM Service update N262547330.

At just over 36,000 miles, the vehicle randomly started jerking to either side of the road. It's not continuous and happens at random intervals while driving. Sometimes the steering wheel would jerk with the movement of the tires, other times, it felt as if the steering wheel had disengaged for a moment. The first time it happened, we were traveling on a highway at 55mph and were jerked towards oncoming traffic. I immediately stopped the vehicle and turned around to head back home at a safer rate of speed. The steering issue continued numerous times until my arrival at home. This issue just happened today, so it has not been inspected by anyone yet. There were no warning lamps, messages, or other indications.

The car seat anchor system is very poorly designed and extremely difficult to use. I just spent an hour trying to ensure the seats for our grandchildren are installed correctly. The upper anchors are poorly placed, difficult to access and do not inspire confidence the seats will be secure in the event of an accident. This is after I had to take the truck in for a warranty claim because the lower car seat anchor on the back seat passenger side was covered by factory upholstery and could not be used at all. It’s very frustrating when one attempts to comply with safety regulations but poor design inhibits the proper installation of car seats.
