While driving the truck began switching between towing, normal, and off-road driving modes. Lights were flickering and various messages were being displayed on the dash cluster screen. After parking truck and shutting it off all of the lights were flickering and I was unable to start the truck. Charging the batteries did nothing nor was I able to jumpstart the truck with another diesel. After repairs for these issues, at some point the odometer reset and while likely not certain it reset to zero. GM has no way of knowing when it reset and how many miles were driven between leaving the dealership and the reset leaving me with a truck set to the best guess mileage. I am being told this was a software bug and having experienced another software bug when I had the recall to enable seat warmers where the keyfobs would not work in any way I have serious concerns about the quality and safety of the software on these trucks.

I purchased 2022 GMC Sierra HD last year. Due to Micro Chip shortages at the time GMC provided custo.ers a $50 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.
