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?

Power steering goes out while driving making it hard to steer. Very dangerous it happens out of nowhere.

- Oak Hill, OH, USA

Vehicle was in motion driving down the highway when complete power steering failure occurred. It was raining at the time, and this took place approximately 30 seconds after driving through a shallow puddle in my lane with the driver side tires. Vehicle was immediately very difficult to steer, even at highway speed. I am a fit male with strong arms and it was almost more steering resistance than I could manage. Had this occurred while turning, I doubt I would have been able to control the direction of the vehicle. Even while driving in a straight line, if this had happened to a person with very much less upper body strength, they would have been in real trouble, as they would be unable to steer the vehicle safely off of the roadway. The shop diagnosed the problem as being a failed electric powered rack and pinion (steering gear). They said that this was not related to the previously issued recall on the power steering, and that it required replacement of the apparently shorted out steering gear.

My electrical power steering has given out. I cant steer whatsoever. It is on recall. We fo have a local shop but it is not a GM shop. We did try working with GM and also the seller-ak sales and service to try get it fixed. They will not help me whatsoever. I love in the bush which means we have limited access. If I wanted to get this fixed I'd have to pay out of pocket over I grand to get my vehicle barged to amchorage, ak. Which I dont have that kind of money. I still owe over 11 grand on my truck. I'm sol as to what to do.

While driving at low speeds the steering wheel jerks and is very difficult to turn and fails to turn and can sometimes be pulled right out of your hands while attempting to turn. When this occurs while negotiating a turn it causes the vheicle to fail the turn, turn very widely and forces the vheilce into the oncoming lane. This vehicle apparently has a recall on part of the power steering assist, but the power steering rack needs to be replaced and GMC will not cover the replacement even though it is all one unit.
