    While driving on the highway, I got a message that said "low oil pressure, turn off engine" with red flashing lights. I could also smell burning oil and metal. I immediately pulled over and turned off my engine. When I exited my truck, I could see all of the oil that remained in my engine leaking onto the ground. My truck was towed to a local repair shop and they advised me that this is a common problem in this truck. The oil line blew likely due to a defective crimp. The mechanics can't repair the problem right away because this line is on a national backorder and there is no aftermarket option. This obviously happens too often if this part is on backorder. The mechanics believe there may have been damage done to the engine as a result of losing all of the oil on the highway.

    Engine began having ticking noise. I took it to dealer for repair. Service department finds the lifters in my engine have failed and destroyed my cam shaft. They call me and explain it will cost $10,000 to repair. The service writer explains to me that they have 4 of these each week come into the shop. It is so common that they keep the parts in stock to repair. While I was waiting in the waiting room another person came in with the exact same problem. I later found that a repair bulletin has been issues for this issue but for some reason it does not apply to my vin even though it is the exact same problem.

    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.

    The rear window on the 2019 GMC Sierra SLT leaks water into the cab. This presents a serious concern to the owner of the vehicle because unless you are specifically looking for the leak you may not even know there is one. Upon noticing the leak, one can witness a steady drip of water behind the rear seat, drivers side. My personal concern is that what happens after the water has leaked and had gone unnoticed for an extended period of time, does mold start to grow? Does my truck have mold growing in it? With two young children in the vehicle I am concerned about their health and safety. My frustration with this issue is that GM refuses to acknowledge that there is an issue. My dealer has brought this issue up with GM but the claim has been denied. I have no idea how long the leak has been happening but it’s a manufacturing problem that exists and it certainly shouldn't be the owners responsibility to fix the problem. More importantly, it shouldn't be my young childrens health that is affected by the manufacturers incompetency and ignorance.
