Driving back to camper in the late evening and was listening to music and gps was on the screen when I was going approximately 32mph when headliner airbags on both sides went off causing me to hit my brakes and veer into the ditch. I was able to maintain pretty good control but did hit either a rock or stick or something that punctured my wheel sidewall. Unsure if a tree limb then got caught and tore off my bedcover that then left a small dent on the c column on the passenger side. I was able to put my truck in 4wd to get back fully into the roadway and walk about to see potential damage. At that time I only saw my tire was loosing air and bedcover was off aside from the airbag deployment. I slowly made my way home to assess further during complete daylight. I was not injured other than a cut on the hand due to the bedcover and a headache from the deployment. No hard hit or collision and truck did not make contact with tree trunk or any front end damage that would ordinarily come from someone going into the ditch. Reached out to a shop to have them check it out and see if they can see any reason why those airbags would have deployed without force then causing an incident

The 4WD system engaged unintendedly, and the park assist sensor was inoperable while an unknown message was displayed. Additionally, the vehicle lost motive power while driving.

The contact owns a 2022 Safe Haven 12-foot Flatbed Trailer. The contact stated that while driving approximately 10 MPH and towing the unloaded trailer with a 2024 GMC Sierra 2500, while slowing down to make a right turn, the trailer detached from the tow hitch ball. The contact stated that there were no warning lights illuminated. The contact stated that the aluminum arms on the hitch adjoined to the frame of the trailer was loose. The contact stated that because of the design of the hitch, the receiver that rests on the trailer hitch was not flush, and there was room for the trailer receiver to move up and down, causing the bolts to loosen. The contact called the manufacturer and was informed that it was the normal of the bolts. The trailer was taken to an authorized dealer, and the contact was informed that the trailer was attached incorrectly. The vehicle was not diagnosed or repaired. The failure mileage was approximately 1,200. The VIN was not available.

The vehicle went into low power mode and said to pull over. As soon as that message appeared the next warning appeared and said to shift to neutral and pull over immediately and attempt to restart. The vehicle immediately shut off after second warning before having time to pull over from first message. I was able to pull most of the way off the road as the vehicle had shut off there was no power steering and had limited ability to steer the vehicle. This all happened without advance warning or any other warning that there was an issue while traveling at over 75mph. Vehicle would not restart and needed to be towed. Dealer stated it was a fule control module that was hard to get due to a recall. But that my vehicle was not part of that recall.

Oil cooler blew and mixed oil in coolant reservoir. Possibly causes overheating and engine seizure. This has been confirmed with a certified GM service center. The service center inspected fixed it then within 5 miles had to be returned to the dealer because it happened again.

Traveling on I-10 doing approx 75 mph head a loud boom and saw sparks coming from the read drivers side of the truck. Truck was riding a bit low on that side. Pulled over and determined the tire had blown up. Currently doing the insurance claim and repair as there was substantial damage to the truck. No crash or involvement by other motorists. Did not hit anything.
