AIR BAGS, SEAT BELTS, SEATS
On July 27, 2022 I was driving my 2022 GMC truck on the freeway. I was rear ended by a semi truck and the passenger side was side swiped by the semi. I was driving the truck with my wife and two kids as passengers. The truck was completely totaled. No airbags deployed and the seat belts did not restrain us. All 4 of us were wearing seat belts. Also, the drivers seat completely broke, it looked like it had been completely reclined to a laying position. A police report was made. All 4 of us were taken by ambulance to the hospital. All 4 of us needed medical care. The truck was totaled and towed, the insurance has since taken possession of the truck. There were no warning lights, service lights or any indication that there was anything faulty with the truck. We had just purchased it in February 2022. My safety, as well as the safety of others was put at risk. The semi truck driver stated he was driving 60mph. If this isn't enough for air bags to deploy, I don't know what is. The seat belts also failed to restrain us. The seat belts were completely loose and during the accident failed to secure us. Again, the drivers entire seat completely broke causing severe head, neck and back injuries.

FUEL/PROPULSION SYSTEM
While driving to work with my workers and I on HWY going 70 mph pickup just turned off on me and no longer started up. Took to Mechanic and said it was the Bosch CP4 failure. Metal debris flooded our entire high-pressure fuel system. Had to get replacement of fuel lines, fuel rails, pump and injectors and the removal/flushing of the fuel tank. Our total repair is over $12,000. which we don't have. Mechanic just finished repairing it after 11 month's but we don't have the $ to get it out from shop.

SERVICE BRAKES
*A message and alarm kept going off on our truck "Service Trailer Brake". We are not towing a trailer, nor had we had a trailer hooked to this vehicle since 2019. It began only going off occasionally, but within a few weeks it was going off constantly. It would show repeatedly on the dash and the alarm would sound over and over. Trying to turn off the system was not successful, no matter how many times we hit dismiss. It was totally distracting and worrisome that something was wrong with our braking system in general. *The constant alarm and dash display made driving a very distracted experience. It is so loud that you cannot hear other outside noises. We were also concerned about the safety of our regular braking system. *I called the dealer where our truck is regularly serviced. They immediately said "Is it the Trailer Assist Alarm?," so it was obvious that this is happening to other owners regularly. It took several days to get in for an appointment. The shop mgr helped us to locate and pull the alarm fuse to stop the noise, so we could drive it to the dealership later in the week. The display was still going off when I pulled the truck into the dealership, as it has done all the way there (17miles from my home). *It was inspected by the GM dealership (Schwarz, INC. Honesdale, PA) and the defective switch was replaced at a cost to us of $127.14 on 08/11/2022. *This issue started several months ago (Feb 2022?), but it was a one time thing. So, we thought it was just a fluke. Then, a month or so ago it started again, but was happening only once or twice and would then disappear for days. Then, 2 weeks ago it began to happen continuously.

I am getting a service alert for the Trailer Brake System. It is constant and loud and distracting and a significant safety hazard, not only because of the distraction, but also because it renders trailer brakes completely useless

AIR BAGS, SEAT BELTS
The “Service Safety Restraint” alarm goes off continually on my 2021 GMC Sierra 2500HD AT4. The warranty is no longer valid as at the time of occurrence I was at 34,500 miles and when I took it in the warranty had expired due to exceeding 36,000 miles. Extended warranties were not purchased and this began approximately 8-9 months after purchase. The code given is “b0014 Driver Seat Side Air Bag Deployment Loop” with a description of high resistance in wiring or wiring harness. After much research I have found that many GMC 2021 vehicles and previous models have had this exact same issue. No dealership as of yet has offered to help or understand that this defect was of their own flawed design. The issue that I am having is exactly the same as other models such as the 2021 Yukon, Sierra 1500, Suburban and others. This is a safety issue and only want GMC to account for their flaw. I do not believe I should have to pay for a design flaw or equipment malfunction that is well known amongst GMC vehicles. I am asking the NHTSA to help me in this matter and the many others who are having the same issue and for the manufacturer to be accountable for their own flaw.

UNKNOWN OR OTHER, POWER TRAIN, FUEL/PROPULSION SYSTEM
Cold start after vehicle sits for a while vehicle shark bites and stutters. When you try and drive vehicle before it’s been warmed up significantly. It’s a safety concern because it feels very danger and could cause an accident. Alamo At caused my truck to stall out the other day with my children in it and a large accident. Dealership is dismissed my concern and says it’s normal gmc defects that I have to deal with. I will sue GMC if I have to.

SERVICE BRAKES
Brake are very spongy all the time we’ll While driving in parking lot at low speed we lost brakes happen to hit person in front. This has been a continuous problem to point we are scared to even use the truck to go to store. Took it to Firestone. They told me it was the master cylinder. So they replaced that, replaced the front rotors and pads, did a fluid exchange abs as well? Don’t know what that is. On the internet there is tons of this issue. I even see GMC 1500 is having this issue and there is a recall for the recalibration electric brake controller? Couldn’t it include the full Sierra line?. Why not on the 2500, 3500? Looks to be same system? Rotors and calipers are different thats it If anyone can help please let me know. It’s not covered under warranty and they want to replace some pump for $1500. I just paid $1500 for something totally different

POWER TRAIN
After an unexpected battery failure, truck shuttered and jerked violently when coming to a stop. Replaced battery and was driving home when shuttering returned and dropped into neutral as if it was trying to find the gear. Pull over and was within inches of being rear ended as it rolled to a stop on shoulder. Forced to abandon vehicle while waiting for tow truck for safety. Concerns were raised to dealer around 50k miles when something seemed off, but was dismissed with the excuse that it was normal. Now with 120k, I have nothing more than a $45k yard ornament.
