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.

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

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.

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?

**beware** I own a 2014 GMC Sierra denali that abruptly shuts off on me while driving with no warning. I took in into the delearship and they stated that they fixed it. About a little over a year later it started acting up again off and on. I didnt want to deal with the dealership because they always say "it is not covered under warranty" although it only got worse. I ended up taking it back to the delearship recently because it got to the point where my truck was shutting off on me every day in the middle of the road. This was an accident waiting to happen! the dealership after over one week finally found that it is an electrical harness issue, sending the wrong signals causing my truck to abruptly shut off. They are charging me over $900. This should be a recall! how in the world is this not covered through GMC! I will never purchase a GMC vehicle again.

During normal driving in town and on highway, stabillitrak deactivated and power steering assist deactivated flashes on dash. The air conditioner and radio flash off. Lose power steering. The whole truck shut off also once while reversing, went from park to reverse and shut off. This had been very dangerous, as it happened also while going 70 mph on the highway.

Takata recall, parking assist sensors quit working. ABS lights stay on with the alert "service stabilitrak". manufacture faulty electrical ground is possibly the source of the problem. My truck is not even 5 years old yet. There have already been a lot of reports of this same issue by other owners. This is a safety problem that can cause collisions when depending on this feature to work.

  • 76,000 miles
The GMC Sierra truck will loose power steering while it is being driven. This has occurred three times so far. There appears to be some type of electrical error with the trailer brake. Then, numerous warning lights come on and the truck looses power steering. It is dangerous and difficult to drive at that point. It is random. The truck will connect again and everything will function like normal. The truck was taken to a GM dealership and they said there was communication errors. The fuse block was replaced for almost 600 dollars. Then, the vehicle did the same thing again after that repair. I took it back to the same dealer. The vehicle was at their shop for 8 days. They were unable to get the error so no repairs were made. I have contacted GM Corp on three occasions. The senior advisor assigned to my case has not ever contacted me about the issue. They advised that someone with GM would contact me in 2 days. It has been over 8 days. Picking the vehicle back up from the dealer. This is a safety hazard. I feel that the GM engineers have knowledge about these issues but no one will even call me back. There is some electrical glitch that can cause the vehicle to loose its power steering. Research shows that 690,000 trucks were recalled in 2017 in reference to recall # 17276. The dealership advised that my truck received the necessary items for that in 2017. I don't know what to do. I currently have a truck that is not safe and GM doesn't seem to be concerned about it. It is a safety hazard. I'm sure other truck owners have had similar issues. I do not want someone to be injured or killed because GM will not step up and handle this issue. I lost power steering on May 14th, 15th and 23rd 2019.
