The truck shuts off while driving which disables the power steering, engine and power braking. The electrical systems seems to reboot and turn back on after a second or two. This also happens occasionally while driving at slower speeds and turning the steering wheel or after hitting the turn signal. I have had the entire electrical system and engine shut off while doing 50mph on the high just because I turned my turn signal on. This happens every 4 weeks or so. You can tell it is about to happen when the headlights start deeming when tapping the brakes or using the turn signal. It usually happens when the truck is in motion. It has happened in all temperatures. After it happens the console states "stablitrak is disabled".

The vehicle was in motion and took a turn the dashboard chimed and showed a "service stabilitrak", and redcution in power steering, and HVAC went off and came back on and I lost power steering. Everything flashed and flickered. Upon further assessment at my house stationary turning the wheel reactivated the problems and it was also noticed that the lights would flicker and go dim along with the dashboard lights. Looked up some recalls and saw some recalls on 2014 GMC Sierra with loss in power steering, however my vehicle was not included in that. I have a brake recall that I will be servicing and hopefully that might solve this dangerous electrical problem.

Driving on highway and also at low speed, truck completely shuts down electrically. Steering fails, instrumentation fails, doors lock, complete power failure. This has occurred backing out of driveways, turning into intersections. Brought truck to dealer, they can't find anything, but G218 ground issue appears to be obvious yet, they refuse to fix unless issue is present.

- Budd Lake, NJ, USA

In the last 2 months my truck has lost all electric power while making a slow right turn. Voltage drops and I lose power steering. Dealership put a new battery despite there being an active recall for this exact issue. However, my VIN number is not included in the recall. I was able to video it happening. It happens when the vehicle is in motion

- Fernandina Beach, FL, USA

My vehicle turned completely off and it put my breaks to the floor at 26 mph. My steering locked also as if I turned it off. Prior to this happening 3 months my steering column has a popping feeling. Not noise. Feeling. When I took it to the shop, they read the code and it said something along the lines of communication error. Dealership couldn't find anything wrong, took apart steering column nothing was loose and popping stopped also had battery replaced 7 months prior and no bad connections. Received my truck back, was good until a week ago the popping feeling, is back.

- Sioux City, IA, USA

Was driving through a local parking lot, going only 3 miles an hour and started to turn left when all of a sudden the driver side wheel just snapped off throwing me into the steering wheel. My right arm got a scrape and right shoulder popped. The truck hit a metal pole and dented the driver side panel, missing the head light. So glad this didn't happen on the highway.

The vehicle had been repaired since the accident. The failure mileage was 82,000.

- Valdez, AK, USA

I was turning into my parking spot at work and the truck would not let me turn, the power was shut down and my steering wheel jerked. It took three minutes to very slowly pull into a parking spot. Every single time I tried to.turn it would shut my truck down and jerk the steering wheel. Then displayed service stabilitrac. All I can think is what if I were turning onto another road with my kids in my truck and my steering goes out. I'm highly disappointed I've had the truck less than 24 hours and already an issue.

At speeds highway speeds 50 and above the truck can shack horrible causing to apply vehicles hazards and pulling off the road for feeling like the truck is coming apart with the fear of loosing control of the vehicle. The horrible shack cause nausea and dizziness. I have replaced wheels and tires, shocks, re aligned and balanced multiple times nothing has fixed the issue.

Steering assistant disabled and stability track has been coming on and the gauges blink off then come back on make it hard to steer just for a second going down a city street and when stopped at a light.

- Sidon, MS, USA

When I am slowing down to turn as I turn the steering wheel I loose power to my instrument panel and my A/C and radio turns off for a second and then comes back

- Biloxi, MS, USA

Gauges flicker, headlights dim when hitting breaks, stability traction comes on, 4X4 has locked in. Truck has lost all power. Had to reset truck by removing battery cable from battery for a short period.

- Oakwood, IL, USA

This incident occurred 4-5 times over the last week driving between 25-40 mph. While driving, a warning or notification pops up on the dashboard screen stating stabilitrack off or steering assist off, which stiffens the steering wheel and I can't turn the truck at all. At one point, the notifications popped up and then my A/C went off and radio went off along with my entire vehicle. I had to slam on my brakes, place the vehicle in park, and then restart at which point it came back on and worked until I could pull over and assess what had occurred. I attempted to call GMC customer service (800-996-9463) and advise them of the problem and they acknowledged a recall (#17276 - loss of steering assist), but it didn't apply to my VIN#. it only applied to 2014 models of both Chevrolet Silverado ld and GMC Sierra ld vehicles, whereas my vehicle is a 2014 GMC Sierra ltd. They advised that a GMC dealer could "reprogram the eps module software", but the cost would come out of my pocket and they wouldn't acknowledge any fault or recall issue. My concern is obviously the fact I have kids and Transport them to and from school and sporting events. I couldn't even imagine this happening with children in the vehicle and causing an accident or worse injuries to passengers or the driver. This is a major safety issue, and I'm surprised this hasn't been addressed or acknowledged by GMC.

When truck is at low RPM (usually turning into parking spot slowly) truck will shut off. Its pulling to much power from cpu or alternator and killing truck. This is a safety issue.

- Cleveland, TN, USA

While traveling to denver Colorado, my power steering shut off at random on the interstate. I pulled over and turned my vehicle off, and it came back on. A few days later while driving in the snow, it went out permanently and I was stranded until a tow truck arrived. It took 3 days to get my truck fixed, and the whole steering system, rack and pinion, had to be replaced. It cost me over $2,500 to fix and get back home safely. I was traveling on a straight road at 75mph on I-70 West when the steering went out the first time. The second time, I was making a left turn and it went out and nearly caused a wreck.
