The gauge cluster flickers and goes blank completely while driving, over head windshield screen display still works, and throws an - Accretion speed limited- message. Truck has electronics software issues, climate control flickers, works sometimes, most times doesn’t, loose electrical connections. Over all the gmc truck is a major software glitch and GMC does not want to take accountability for there lemon product which is very costly in repairs. Gmc service is not great and the warranty period of 36,000 miles is not justifiable. My truck has 68,000 all highway miles, not city miles. 2024 gmc Denali top in its class, and still has more issues than my 2007 gmc Sierra

While operating my 2024 GMC Sierra EV Edition 1 at approximately 21,000 miles, a "Service Power Steering" warning appeared. Steering effort initially increased and then rapidly progressed to a near-complete loss of power steering assist. The steering wheel became extremely difficult to turn, making anything more than a gradual sweeping turn nearly impossible. I was able to safely exit the roadway into a parking lot. After shutting down and restarting the vehicle, steering assist returned to normal. No crash or injury occurred, but I believe this represents a significant safety risk because loss of steering assist at highway speed could result in loss of vehicle control.

I am reporting a recurring potential safety defect involving the front fender liners on my 2024 GMC Sierra 3500. The vehicle currently has approximately 10,000 miles. During that time, at least five front fender liners have been replaced across both sides of the vehicle for the same recurring problem. During highway driving, the front fender liners appear to lose their intended shape and rigidity. Portions of the liner deform or move inward and make physical contact with the rotating front tires. The condition has continued to recur despite multiple replacement liners being installed. I am concerned that continued contact between the liner and tire can generate friction and heat and could po
