Loss of power steering by model year
What owners say
After parking the truck in the garage, the "check power steering," light came on. I immediately lost power steering. I shut the truck off, and about a minute later started it and the power steering worked enough to turn the wheel 1/4t turn to the right and the wheel locked and never moved again. I don't mean hard to turn, I mean would not turn. Had it towed to the dealership in Fairbanks, Alaska and they verified that the wheel would not turn at all. Recommended replacement of the streeting box. There were no prior indicator lights on the truck and little warning of failure. Losing ability to control the truck could have got me in a bad accident. I understand that this was an issue and there was a GMC recall, but my truck was not part of that. The Fairbanks dealership said they never saw one lock up light that before. The truck does have a damaged title due to a house fire and the truck was parked near the garage and it melted the plastics/grill etc. Repairs were made by a certified body shop.

The electrical system has intermittent issues with connection to the battery due to the location of the ground connection from the battery. The ground connection is screwed into the under carriage (near wheel well front passenger side) and left exposed to the elements. Grit and grime build-up over time caused an interference with the connection. The safety issue is the vehicle lost power without warning and while driving causing the vehicle inoperable, including no power steering. Other symptoms include stabiltrak and park assist errors displayed while A/C & radio resets during intermittent power connectivity. Cleaning the ground connection wires & screw solved the immediate issue. This video explains it all, including where the issue is located and how I was able to fix the issue to restore power: https://youtu.be/KrSJJUUo9FU
Several instances in which power steering assist lapses at low speed. Several times lapses coupled with radio/ac going off. Two times the truck has died while backing into garage. I have narrowly missed hitting other cars while parking in various places. I have not taken the truck to a dealer or service center for this problem. It has not been inspected by manufacturer, police, insurance or others. Several different messages show up in different instances. Today I noticed “parking assist symbols not available.” Then the truck died.
When decelerating and turning left the car goes completely dead. First time I just about got killed on the highway. The other two times I knew to put it in neutral & crank the car. No steering no nothing. Days Chevrolet in Jasper, Gais trying to tell me there is NO RECALL on my serial number. I see there were a lot of them years ago. In addition to that my power steering occasionally goes out. The last time I was backing into my garage when I had to manually turn it. Hard to do for a woman.

Power steering goes out and at time turn truck power off whenever i attempt a slow tight turn like backing into my driveway or making tight turns going into parking lots and/or spaces. Most recently, when attempting a u-turn at a busy intersection, power steering went out and engine died. I had to coast to the side to avoid moving traffic. Each time this issue happens i hear 3 dings all my dash & screen lights flash off then on with clicking noises. Dash info changes from speedometer to radio setting. If i look at screen quickly enough when this happens i would sometimes read “rear parking assist unavailable” or something like that. If air conditioning is on it would turn off then on. Doors will unlock then lock, all this happening simaltaneously while attempting to make a turn
