On [XXX], I was driving my 2016 Yukon Denali on a trip to Maryland. While in Maryland, I was driving my vehicle. As I approached a street to make a right turn, I braked to make the turn. I slowed down to make the turn. As I made the right turn, my steering wheel ability became hard. I felt a stiffness in the steering wheel as I came out of the turn. My Denali became un-maneuverable. I lost my power steering ability in the steering wheel and I observed my power steering service light indicator warning come on. I pulled my vehicle to the side of the road and turned off my vehicle. I started the engine with no change in the steering mechanism. After twenty minutes passed, I restarted the engine. I was able to drive with normal power steering conditions. On [XXX], while driving my Denali, I lost power steering maneuverability while driving. My power steering service light appeared and indicated service was needed and that the Electric Power Steering (EPS) Assist failure occurred. Based on research, It appears that the same problem has occurred in other models of GMC vehicles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle randomly locks up and shuts off while I am taking a sharp turn or parking. A 'Service StabiliTrak' warning flahses on the dashboard. The steering wheel locks and the only way to get this warning to go away is to turn the vehicle off. This is a dangerous hazard as the vehicle can come to an abrupt stop in traffic.

The largest issue was today, 2/22/2022, when I was driving doing 56 miles per hour it felt like it wouldn't accelerate. Then all of a sudden, the wheel kind of jerked right and the car shifted down all on it's own and I was doing 25 mph. The check engine light came on immediately after the violent jerking happened. I was on a 4 lane highway and had to immediately pull over onto the shoulder. It was jerking forward and back as I was trying to pull over on a freeway where the speed limit is 70 mph!!! I had my 80-year-old mother in the car with me. AND YES!! It put us both at great risk! I had to call a tow truck and they towed it to a dealership 9.8 miles away. When I talked to the Assistant Manager, he said that there were 3 other GMC Yukon 2016 that had come in today - ALL WERE 2016 GMC YUKON MODELS WITH 125K MILES. My GMC has 124,700 MILES all with Transmission problems. This can't be an anomaly. So I got online and there are many, many complaints about this transmission. As a matter of fact, it appears in 2019 there was a Class Action Lawsuit about this very thing. I will not know until tomorrow for sure what the issue is - because the dealership could not get to it today. However, something significant happened. As a side note, recently I had an electrical problem where sensors, etc are all saying need to be serviced and none of them are working. I had appt today at 10:30 am to have them check this. On the way there, the violent jerking and sudden downshift and check engine light came on. I was scared to death and so I pulled over and called a tow truck. The dealership did not tell me this is a common issue, nor was I aware. The dealership told me if it is in fact the transmission - cost is $6,000!!! I need someone to contact me to discuss this.

Our GMC Yukon locked into 4WD while accelerating/driving (approx 15-25mp) the kids to school through the neighbourhood, jerked violently as though braking hard, and steering was extremely impaired. The "service 4WD" message appeared on our dashboard. The Yukon is locked in 4WD, and extremely difficult to steer and maneveur. It jerks violenly when turning. We are unable to drive due to safety concerns.

My ac started blowing hot air. The air compressor was changed twice. After changing it the last time I started getting the service power steering light on and Y steering wheel locks up. No power steering. This is very dangerous and seems to be come type of wiring problem.
