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.

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.

Power steering has went out multiple times when turning in parking lots. Without power steering its very hard to navigate the truck especially when you don't expect it to go out. No warning lights came on and power steering goes back to working fine after these episodes

The first issue is popping coming from the front end of the vehicle causing a steering issue. This has been "repaired" multiple times with no resolution. Every time the popping occurs which is almost every turn the steering wheel will not turn. The next issue is the radio is causing driver distraction by changing stations and screens not just on the display itself but the instrument cluster as well. The radio has been replaced once due to the fact it was on backorder for 6 months another attempt has not been made. The third issue is the brakes have failed at slow speeds no warning lights were on, they just stopped working in the Mcdonald's drive-through. I had to get out of line to keep from rear-ending the person in front of me. Now, after that experience, the ABS light has come on and the service StabiliTrak flashes on the dash as well as parking assist off, everytime I hit the brakes..

- Gallup, NM, USA

Power steering goes out and at time turn truck power off whenever i attempt a slow tight turn like backing into my driveway or making tight turns going into parking lots and/or spaces. Most recently, when attempting a u-turn at a busy intersection, power steering went out and engine died. I had to coast to the side to avoid moving traffic. Each time this issue happens i hear 3 dings all my dash & screen lights flash off then on with clicking noises. Dash info changes from speedometer to radio setting. If i look at screen quickly enough when this happens i would sometimes read -??rear parking assist unavailable-?? or something like that. If air conditioning is on it would turn off then on. Doors will unlock then lock, all this happening simaltaneously while attempting to make a turn

Pickup has had reoccurring service power steering message come up in information center. Took to GM and they said it needed a new negative battery cable. Bought one and installed it. Still have the same problem. Upon dong some searching, its a very common problem among certain GM vehicles. One weekend the power steering quit working all together at 70 mph on a curve. Talk about scary! I called GM customer service to ask about coverage on the issue and was denied because my vehicle was not one affected by the suspect faulty parts. I am very disappointed in GM's lack of caring for my safety in this situation. Will not be purchasing another GM. If they no that this is their problem I truly believe they should stand behind their product and take care of their customers.

When turning the wheel sharply at low speeds, the power steering suddenly turns off, as well as all other electronics making the vehicle difficult to control and posing a safety risk.

At slow speeds, mainly when backing and turning wheel when going forward at very slow speed, steering loses power. Also some times hard to turn when vehicle not in motion at all. The last time it happened all interior lights and radio flashed totally off and right back on. I heard a dinging/warning noise and a warning message flashed but went off before I had a chance to read it.
