Jul 8, 2026SteeringSuspensionLane Departure

I am reporting a safety defect involving my 2025 GMC Hummer EV 3X (VIN: [XXX]). On XXX at approximately 18,880 miles, I first presented the vehicle for steering/alignment, suspension, and handling concerns. As of this complaint, the vehicle has approximately 26,840 miles. I have driven nearly 8,000 miles while repeatedly reporting unresolved safety concerns and transporting my two children (ages [XXX] and [XXX]) because I had no practical transportation alternative. Following warranty repairs, including rear control arm replacement, the vehicle developed a severe pull to the right that did not exist before repair. It requires constant steering correction to remain in its lane, and Super Cruise can no longer reliably maintain lane position. Premature and abnormal tire wear has continued throughout the unresolved alignment condition. The vehicle has undergone six warranty-related service events at two authorized GM dealerships. Despite repeated repair attempts and two direct escalations to General Motors requesting repurchase, the only resolution offered has been additional diagnostics and repair attempts. A courtesy loaner was not offered until the sixth service event, after months of unsuccessful repairs, thousands of miles of continued operation, lost wages, and repeated travel. The vehicle also continues to experience water intrusion despite warranty repairs. Rainwater enters the passenger compartment, leaving a persistent musty odor and raising concerns regarding mold, mildew, occupant health, and interior deterioration. I have filed a Georgia Lemon Law claim after exhausting GM’s internal process. I also documented my experience publicly. Posts received approximately 17,500, 48,900, 60,100, and 24,800 views. Many GM owners described similar repair experiences and unresolved INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2025 GMC Hummer EV SUV verdict →
