All power shuts off while driving. The transmission dis-engages, the power steering stops working and the infotainment system turns off. The power steering powers off even when sitting in a parking spot while everything else is on. I've owned this truck since 2019 and this has always been an issue, especially when taking a left through an intersection. I keep checking for recalls, but nothing shows up and I find that extremely hard to believe. I'm contacting you now because the issue has gotten worse, everyday worse.

When I turn the steering wheel, the ac turns off, lights turn off, the computer screen turns off, steering wheel gets hard and does a jerking movement. The truck turns off too and then suddenly turns on. This can cause a death. If this happens in a highway or a street where speed is high this can easily cause a death.. fortunately this has happened going at 30 mph and no one close at the time and also at a drive through fast food restaurant. It has not been confirmed by the dealer but I will soon have to take it. The only light that comes up is the StabiliTrak.. but it only lights up when it happens and then it goes away.

Truck loses power engine dies while driving after turning at slow speeds. Engine will restart after a few minutes like it never happened does not show any DTC codes or check engine lights. It is intermittent with no advance notice very dangerous to drive. Seems to be a common problem for all GM trucks and SUVS from 2014 - 2017

While going at a low speed, the steering starts to get tight. It is not constant but occurs off and on. I have read online about this recall, but the truck I own was not included. I believe it should be. I can't trust pulling into traffic for fear it will lock up.

- Leland, NC, USA

Several instances in which power steering assist lapses at low speed. Several times lapses coupled with radio/ac going off. Two times the truck has died while backing into garage. I have narrowly missed hitting other cars while parking in various places. I have not taken the truck to a dealer or service center for this problem. It has not been inspected by manufacturer, police, insurance or others. Several different messages show up in different instances. Today I noticed -€œparking assist symbols not available.-€ Then the truck died.

1. Truck is equipped with AFM (auto fuel management) I found out thru some research models since 2014 having collapsed lifters because of this feature. GMC has not made any attempt to recall this problem and let customers face the repair like me at the cost in my case of 7K. This truck has only 58879 miles on it. Not surprising models as new as 2021 had the same issue with no action taken to correct. 2.My truck lost the steering assistant feature putting me in a potential accident while i was driving. Steering the truck is difficult, especially at low speed which I decided not to drive it. I'm 87 years old and I'm facing numerous repairs for a vehicle with only 58K miles on it in order to safety drive my vehicle

I started the truck and did not have power steering. If this would have happened while driving it could have been very dangerous. Why is this not a factory recall?

Truck will experience complete electrical failure while driving in motion at various speeds. Failure lasts between 5-10 seconds but causes severe difficulty as steering is affected. A web search reveals grounding issue as potential cause. Manufacturer has not notified me of this particular issue and or any recall effort and I know of no existing recall effort for this issue.

- Montgomery , AL, USA

Becomes hard to turn steering wheel at slow speeds, more often while in reverse. On one occasion, a Stabilitrak message popped up as a warning and then the engine died. Does not happen every time but has happened enough to take it to the dealership. They concluded that it could not be duplicated so they could not properly diagnose the issue. They had the truck for 3 days of testing. The engine failure is seriously concerning to me due to having my children with me most of the time.
