SEAT BELTS
On my 2014 GMC, the front driver side seatbelt was not latching. We had to finagle to latch it. To which this point we were unsure that we were safe. So I brought the GMC to the GMC Rosedale dealership and after further investigation they charge me $522 to repair replace the belt. I told them it’s a safety issue, but they seem not to care, I also contacted GMC corporate and they are investigating this. So if it state law that you have to wear a seatbelt for your safety, why do dealerships charge you to repair or replace them.?

The passenger presence module does not work. The deal said if it was involved in a crash there would be a possibility the airbag on the passenger side would not go off because it can't register if someone is sitting in the seat or not.

ELECTRICAL SYSTEM, STEERING, POWER TRAIN
At slow speeds, multiple times, I have had the truck completely have an electrical failure and the engine shut off. I have replaced the negative battery cable and ensured all connections are good. This has happened on streets when turning and in parking lots. When this happens all of the screens in the truck flicker and the service stabilitrack light comes on and then everything goes out, to include the engine. Myself, my family, and other drivers have been out at risk when the truck completely shuts off on a street. The dealership has not been able to give me an answer. There are many forums online where the 2014-2018 year models of this and similar GM vehicles have had the same problem. We need a specific fix for this before someone gets seriously injured or killed.

ELECTRICAL SYSTEM
Backing out of driveway, suddenly lost the transmission. I was stranded at about a 45-degree angle into the traffic lane. I had no gear position indication (an automatic) and couldn't move the truck under it's own power. Shut it off and restarted twice before I got it into "limp-mode" and, while abrupt and harsh, managed to get back into my driveway. Found fault code U0101, Lost Communication with TCM (Transmission Control Module). Had never heard that this has become a common problem. Discovered quickly GM has no parts available, no repairs available, and that it is happening to thousands of GM trucks from model years 2008 to 2015. The truck is useless without this module function. We use this truck to tow a 12000+ lb. travel trailer. I can't imagine how bad this could have been in freeway traffic with such a load. Have been told GM put the part on a national back order in October of 2022, with no estimate of availability. It's now late August of 2023 and still nothing available. Has me concerned that one of these vehicles could stall right in front of me in traffic! I can't afford to replace this vehicle, can't move it, and am relegated to going to work on a motorcycle- in traffic with other GM trucks just waiting to experience this failure. And winter is coming...
