“I was driving down a busy 3 lane road with a 55 mph speed limit. By the Grace of God, I had just turned from the center lane to the right (outer) lane when our Yukon lost ALL POWER and the display read something like "Press Start/Ignition." I was utterly confused…”

“On January 10, 2026, at approximately 1:00 a.m., while traveling at highway speed (approximately 65+ mph) on a multi-lane highway, the engine suddenly failed without warning, resulting in a complete loss of power. I was forced to make immediate evasive maneuvers to reach the…”

“This vehicle was identified as recalled in 2025 for total engine replacement and the engine did fail in May 2025 it would stall while driving. GMC performed the engine replacement in June of 2025. The car stalled again on Friday May 1”

“As I was driving I lost all power going up a steep grade in the fast lane of a 4 lane interstate. There was no room to pull over to the left side so I had to very quickly cross 4 lanes of traffic without any power”

“The valve body failed on 6/4/25. This caused the car to have a sudden jerk and then suddenly decelerate while driving with my children in the vehicle. It could have caused an accident if another vehicle had been following behind”

“SUV appears to get stuck in gear or struggle shifting causing jerky behavior and erratic drivability. Stopped driving and had it towed to dealer. Dealer stated Engine Code P0747 shown. Dealer stated faulty transmission valve body but no ETA on parts”

“While driving through rain on a long car trip, the wipers suddenly became completely inoperable. We could not see and were on a highway causing a serious safety issue. We had to drive very carefully off the next exit ramp”

“Windshield wipers periodically fail to operate when turned on. This is but extremely dangerous because it's been impossible to determine what the cause is. When the wipers stop working, I adjust the speed from the intermittent settings to LO and HI and there is no change”

“Multiple times the windshield wipers have randomly stopped working. Other times were on short drives from home and we were able to get home safely but had issues with visibility. Eventually they would come back on and start…”

“The onboard accident emergency notification system has failed after 2 years. The SOS and Onstar are not functional. Car has no data communication with the network. Was confirmed by Crenwelge Motors in Kerrville Texas”

“The onstar module of my 2023 GMC Yukon has failed. This is a wide spread issue with recent model GMC's. There are thousands of reports of the same thing happenings. When an onstar module fails, the vehicle loses…”

“Onstar connectivity module failed after dealer updates. The onstar module controls super cruise hands free driving. Module can fail during use causing accident. Vehicle did not display any warning on display screen”

“I discovered that the entire fuel tank had fallen out of the vehicle and was resting on the ground. I contacted roadside assistance, and the vehicle was towed to the dealership. The dealership informed me that the…”

“I was driving on Highway 78 from Alabama to Mississippi, when all of a sudden we heard a loud explosion type noise. My husband looked up at the panoramic sunroof, and there was a large hole, along with shattered glass”

“my vehicle has developed a severe and persistent exhaust intrusion that allows toxic exhaust fumes, including carbon monoxide (CO), to enter the passenger cabin. CO levels have measured a peak of 83 PPM and consistent reading between 20-37 over multiple tests”

“carbon monoxide (CO) entered the cabin, exposing my children and me to dangerously high levels of CO and causing confirmed carbon monoxide poisoning. We were driving with the engine running and the heater on for approximately 21 minutes when the exposure occurred”
