ELECTRICAL SYSTEM, BACK OVER PREVENTION: WARNINGS
For over a year now multiple times while I'm driving. My vehicle's power steering will jerk/shake very abruptly, dash lights, radio, a/c & heater flicker on & off, service stabilitrak, trailer brakes etc, will pop up. then once stopped and shut off the engine the battery will act like it is dead and I will have no power to the vehicle at all. I have read the recall report & over 1 million SUV/Pickup GM vehicles (Chevy/Cadillac) manufactured through October 2015 are affected with the same issues. My 2016 GMC Sierra 1500 manufacture date on the vehicle is October 2015. I was told my VIN # was not included with the recall therefore they can't do anything to help. Even though my vehicle is experiencing exactly the same problems as the vehicles that were recalled and fixed with no out of pocket expense I am basically screwed. I also have a video of my steering wheel jerking back & forth, dash lights flickering & the engine stalling. (All in the same video)

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS, BACK OVER PREVENTION: WARNINGS
I bought a new GMC, I received 3 vouchers for computer chips to be installed at a later time years ago. They have not provided them. They are selling new fully equipped vehicles with computers chips just fine. Can you handle and have GMC install their backlog of computer chips? There are many safety features that DO NOT work, like parking assit and basically all warnings like when backing up etc. They made me sign a form stating they are not responsible for safety issues stemming from this (our inability to sue) this should be illegal. Thanks.

VISIBILITY/WIPER, UNKNOWN OR OTHER
No incident as of yet. The wide angle driver mirror cannot be set high enough to see down the side of the truck. It is a factory installed towing mirror. I have to lower my my seat all of the way and I cannot see the top rail of the bed. The mirror won't let me see down the side of the truck which makes it really dangerous when I pull my 32' fifth wheel trailer. I took it to the dealer and they told me at first ( I purchased the truck on 01-22-2023) the mirror is one of 6 items that warranty doesn't cover. Then they told me it is very difficult to get the manufacturer to authorize replacement. The dealer eye balled a mirror just from standing in front of it on a lot truck and said he couldn't see a difference. All I can see out of it is basically is the rear tire. I called GM and the person looking into it was transferred after about a week. The person that took over asked me to give him a week to look into it. He called me today and said he hasn't had a chance yet that he needs a couple of more days.

The headlight was flickering. For a week before it burnt out completely. A flickering headlight causes a distraction to other drivers. Not to mention a LED light shouldn’t burn out in one year.

UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
I purchased 2022 GMC Sierra HD last year. Due to Micro Chip shortages at the time GMC provided custo.ers a $50.00 credit and notice that they provide the chips ASAP and that it should be provided by December 2022. I like many others accepted the risk for not having parking assist sensors and other features for this period of time. I contacted GMC last month after speaking with my dealer and was told by GMC customer service that GMC has instead adopted an approach of providing Chips to new vehicles while they work on getting chips for those vehicles already sold. No where in the agreements that customers signed did it acknowledge that we would be prioritized by GMC in order for them to make new vehicle sales over the increased safety risks. I drive a GMC HD (3500) which has significant blind spots and Increased safety risks to pedestrians as a result of no warning detection systems during parking in lots and on streets. I would like to have this risk mitigated by having GMC honor the agreements and commitments to its customers by providing the Micro Chips required to fulfill these safety requirements ahead of new sales, so no injuries or loss of life are sustained as a result of this profit over safety stance that GMC has adopted. I would like the NHTSA to assist consumers in addressing this safety issue.

STEERING
I was getting off the freeway making a slight left turn yield and from the no where the steering wheel by itself turned to the right side almost making me loose control of my truck, I was driving about 45 mph when the incident happened. Then a second time happened about two-three weeks later when I was making a left turn to stop by a gas station, I was making the turn driving about 5-10 mph. This is something very serious. If it happens when I’m in the freeway it could make me loose control of my truck and someone could get hurt.

EXTERIOR LIGHTING, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
I have a 2018 GMC Sierra Duramax Quad-Cab and when it is connected to either my boat, stock trailer, or cargo trailer the lights and electric trailer brakes on the trailers do not work. and the chime from the "Service Trailer Brake" indicator sounds and doesn't stop until I unplug my trailer harness from my truck making it a distraction and an unsafe situation when trying to navigate through traffic(changing lanes, stopping, and other functions needed when hauling trailers). The dealership said it was a module and specified which one and so I elected to replace it myself and it wasn't the issue. I choose to do the work myself as they quoted me a price of $700.00+ to repair the problem.
