My truck on a few different occasions has had the stability of arming come on out of nowhere and go off. When I back my truck in my drive way a couple times when I am going backwards and turning I have had the truck almost die due to the draw from the powerstering pump as I turn the steering wheel. I have had the engine die once while backing it in the driveway leaving me stranded in the street for a minute while the truck seemed to re-boot. When I am in park at night if the truck is running in park with the lights on and I turn the steering wheel back and forth the light will really dim and pulse as the steering wheel goes back and forth. With these issues I hope that this doesn't happen at an intersection or somewhere with more traffic and cause an accident that I have no control over.
So far it has only done this under low speed making a tight turn like up to a gas pump or into a parking space the dash and display center will flash on and off and the steering wheel will jerk the other direction so violently it pulls the steering wheel out of your hand. Also on the highway while driving about 20 mph I got a warning something to the effect that steering assist had been reduced drive with caution. Even under low speed it could have been dangerous but I'm afraid at some point this will occur at a higher speed. We bought the vehicle used, the factory warranty is gone but I have an extended warranty. I contacted my local chevy dealer because I considered a safety defect that should be taken care of beyond the warranty but they claim they know nothing about this as a problem despite the fact I have seen many complaints about this problem documented, that's what prompted me to file a complaint. The vehicle is currently at my mechanic hoping they can find a cause/solution but I think this is something gm/chevy should be doing a recall on and fixing instead of people having to pay out of pocket or private after market warranty companies having to pay for. I have a video of it doing it on my iphone but didn't know if I could include video and it's currently on my phone and not my laptop. I used 02/01/2017 as occurrence date but I'm not sure of that was the first time or not, we've had vehicle since 12/2016 and it's happened numerous times.
