While driving approximately 70 miles an hour and trying to switch lanes, we got a stabilitrack warning and the car shut off for a second and then came back on. the weather was nice and there was no snow or any other adverse conditions. This happened a couple more times on the ride and then when we tried to turn into a parking spot it shut off completely and we had to restart it. We turned stabilitrack off and the car was ok for a couple of short drives. Then driving late at late and we passed another car the same thing happened. Then when we tried to turn our brights on we got the same message. Then we got a brake assist message and then we got a collision alert. The headlights were flickering the rest of the drive and we couldnt use our brights. We had our 4 children in the car and it was shutting down at high speeds and very scary. I looked up our vin and it said that the recalls had been worked on but I dont remember this being done. This has never happended before this. our car would be available for inspection if needed.

Vehicle lost power steering turning a tight left into a parking space at a low speed on 5/18/2024. A second later, the engine and all electrical in the vehicle went dead. The steering locked and nothing electrical in the vehicle was functional. Based on the online information and comments found, this is a significant problem with the 2015 Suburban. The GMC recall number is 14743. The recall was for replacement of the power steering assist motor kit. When I look up my vehicle on the recall listing there are no recalls for my vehicle. There is an obvious problem which is effecting these vehicles and dealers shouldn't question the safety implications of steering and engine failure while the vehicle is moving.

It started with a glitch with the radio/navigation system flashing back and forth and not working. The cooling fan on the vehicle would run for about 10 minutes. The blind spot warning would blink on and off and there was no one else on the road. Then two days later the check engine light came on for about 5 days. Then three days later there was a loss of battery power and the indication light came on stating the car was in battery save mode. Then two days later the power steering system was lost on the highway and all the warning lights on the dash were flashing. The car stalled and refused to start.

Vehicle loses power steering when turning at slow speeds which was part of a recall from 2018. Reflashing the module didn't fix the issue and has been doing it again for a year now except that now it occasionally loses power as well and has twice lost power while I was turning and oncoming traffic coming at me. GM is saying it is not the same issue as the prior recall, but I disagree and that the work done prior didn't fix the safety hazard. An 8 year old vehicle shouldn't be losing power while driving to where the battery cables have to all be replaced. That should have been the work GM did back when they first put out the recall for the loss of power steering.
