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.

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.

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.

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.

My truck meets the exact description outlined in GM recall #17276 resulting from NHTSA acknowledegement nef-150sm and 17V-414. Instead of re-constructing the description myself, I will just provide the language included in the recall notice because it is exactly the symptoms my truck experiences. I couldn't decribe it better if I tried. From GM recall notification N172085440 "condition: General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2014 model year Chevrolet Silverado ld and GMC Sierra ld vehicles. These vehicles may experience a temporary loss of electric power steering (eps) assist followed by a sudden return of eps assist, particularly during low-speed turning maneuvers. The loss and sudden return of eps assist typically happens within a 1 second period and is caused by an electrical/software issue. If eps assist is lost and suddenly returned, the driver could lose temporary control of the steering wheel, increasing the risk of a crash. Correction: Dealers will reprogram the eps module software."

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

Owned truck for one year, bought used at dealership. Within 6 months, the service stablilitrack message popped up while on highway and power steering diminished. Cruise control would turn off when using the blinkers to change lanes. Put a new battery in and things worked well until yesterday when on the highway and the service stabilitrack message came back again when I used my turn signal to change lanes while using the cruise control. The cruise control also turned itself off. Went to park and the truck shut down for one second and seemed to reboot. It drove fine after that but scared the [xxx] out of me. Luckily no one was around. The headlights have also dimmed when pushing the brake pedal. I see there was a recall but I don't know if this truck had it fixed at that time or not. The website tells me there is only one open recall but for the brake system and this seems to be an electrical problem not brakes. I am contacting the dealership but I doubt they will have an answer and will want to charge me for something that appears, according to this site and others, to be a major issue for this vehicle model.

During normal driving in town and on highway, stabillitrak deactivates, power steering assist deactivates and the steering becomes very difficult, airbags deactivate, turn signals become inoperable, radio shuts off, air conditioning shuts off. This happens while at speed on the highway and at slow speeds. It is especially dangerous when making slow turns as the power steering gives out and the truck instantly becomes nearly uncontrollable (uncontrollable for my wife) in the middle of the turn. I have taken the truck to the dealership and they said nothing is wrong and the best they could do was perform a service bulletin. Issue was not corrected. I found that there was a new bulletin that had a fix for the G218 ground. I cut back the sound deadening from the ground, yet that did not fix the issue either. The truck has done this dozens of times and is incredibly unsafe to drive. How can losing steering, airbags, stability control, turn signals, etc. Not be a safety concern?
