SEAT BELTS
Driver seat belt would not recoil. Took to Royal GMC of Tucson and they said it was not a warranty covered part and would not repair it unless I paid for the seat belt replacement. Obviously, I need a seat belt as a safety feature being the driver so I had them order the seatbelt and they installed it. See attached receipt. I believe this should be a warranty item from the manufacturer as it is defective and a serious safety issue. The vehicle is a 2019. I am the only one that drives this vehicle and I have never had any accidents etc.

The contact owns a 2013 GMC Sierra 1500.

The manufacturer was made aware of the failure and scheduled an inspection however, the results were not made available. The vehicle was not repaired. The failure mileage was unknown.

ELECTRICAL SYSTEM, VISIBILITY/WIPER
I remote started my truck yesterday morning to get it warmed up before loading my family. They all then got into the truck, my 5 year old and 8 year old in the back seat in booster seats. I threw in some more bags into the back of the truck and started to climb into the truck. As I did that my kids were starting to get nervous and my wife was pointing and stating that the rear window slider was smoking. I put the key into the ignition and turned the key on. Upon doing that the smoke stopped but a few seconds later there was a loud bang, similar to a gun shot, and the rear passenger side window shattered. My 8 year old had glass hit her and my 5 year old was hysterical. Needless to say, the 5 hour drive home was not much fun for anyone after that occured.

SERVICE BRAKES, ELECTRICAL SYSTEM
While towing my 7000lb car trailer, I get a message that the trailer brakes need service, then I get another message that the trailer brakes are disabled. At this point the brakes are shut off and no longer work. This is extremely dangerous. The problem is with the truck. It does the same thing with multiple trailers of tried with electric brakes. All of these trailers work fine by my other vehicle with electric brakes for the trailer.

ENGINE
The lifters were replaced leas that 2years under warranty at Pooler Chevrolet. They have stated this is a common problem with this vehicle and they had a lot of these vehicles come in with the same exact problem. Vehicle had no power, engine lights on and valve failure after being replaced before and the vehicle has less than 60,000 miles at 2nd failure. They stated the 1st repair has no warranty to cover such a catastrophic failure and I must pay out of pocket. I argued that it shouldn't have failed with less than. 60,000 miles any expectations of engine failure would be with massive miles and would be expected for some form.of major over haul. Caused emergency as i was in the middle of the interstate upon failure and I almost lost my life. I asked who was performing the repair and they won't answer the request about the repair. They stated it was sent out for repairs and not an in house repair. All repairs have been at GM certified center.

POWER TRAIN, UNKNOWN OR OTHER
I was driving my GMC Sierra upon entering the highway, I was at a stop sign waited for clear traffic when it became safe to do so, I entered the highway and upon excelling up a small incline the vehicle transmission just completely stopped working so as I depressed the accelerator the engine would would wind the RPMs up but the vehicle wasn't going anywhere. I pulled the car over to the side of the road and placed the car in park. Put my emergency lights on and couldn't get the truck to the to go to the area to be free and clear of traffic to transmission engage. I put the car into reverse this is the second time this has happened and this is what my husband recommend I do. When I called him is to place the vehicle in reverse reverse a little bit and then place the car into park and then turn it off. Start the car up again and see if it would engage the gear, it took placing the vehicle in park. After adjusting the steering column and trying it again, the transmission engaged but would not reach the full acceleration. I was on a hill so I put the brakes on and the car brakes would not stop the vehicle. It would bounce and skid a bit as I was on an incline. The transmission was not engaging in reverse either. After resting then it didn't get any speed. There are RPMs just kept whining out. I wasn't able to at first get the car to go into gear after wiggling or adjusting the steering column then it seemed to go in gear but it would only go a few feet and then it the process would start over. this was dangerous as I was on a highway with an incline which means I had no break ability so I was rolling without control. I was able to get the car home and parked in my driveway but as this is the second event that has happened since we purchased the truck I'm making this report. Feel free to contact me if needed
