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.

The vehicle 4WD system remains engaged and will not disengage. Upon further investigation the system effects steering and drivability. Also effects speed of the vehicle. The vehicle utilizes a code C0398 and show a message of the dash service 4WD. This is due to faulty software installed by the manufacturer. Will cause damage to mechanical parts if driven on the vehicle and is a safety hazard. GM reference # issued to me when issue complaint of the out of pocket cost to update the software as required by GM to fix their operating system. My reference number is 9-5058496526. Same issue resulted in 2015 GMC Sierra that caused GM to issue a service bulletin #28770. Software issues are not wear and tear components. GM faulty software is the responsibility of the GM as they can cause safety and damage to the mechanical parts of the vehicle.
