Just because I said we have had GMC vehicles and have been fans doesn't mean I ever said we had decades of reliable service or it was the only brand of vehicle we have ever owned. This is one of many issues me, my brother, and my dad have had or are currently dealing with, it was our loyalty that kept me around longer than I should have. Mine and my dads truck is currently in the shop with no estimate on when we will get it back. I also never said a lube tech, manager, stranger, god, or mentioned any positions of people who past that info to me. The information has been verified many times to me through many different sources. All I did was tell my story in a very short version of it, whether you believe it or not is your choice and if you have something constructive to add instead of trying to discredit my story for no reason at all that would be appreciated.

Hey all, I have a 2021 sierra 1500 at4 and I am at 39k miles currently. It is now in the shop for the second time with lifter failure and will be over 60 days of it in shop when its finally fixed. I have been told by numerous people who work on GMC, including a couple people at the dealership it is currently sitting at, that the lifters are known to be defective and can reasonably expect failure every 20k miles. My first experience with the dealer was absolutely terrible as they tried to have me do useless maintenance at 10k miles a week after an oil change where everything was green. I also had copies of the service bulletins saying that this was most likely lifter failure and it should be the first thing that was looked at, I was told by the manager of the repair shop that I should take it somewhere else if I wanted to tell them how to do there job. It took 29 days to get it fixed and was returned to me twice with nothing fixed and the issue being persistent, only to work perfectly 1 day before the lemon law kicked in for me as well as a bunch of promises from GM head quarters that were not kept. The second time happened a week and a half ago. I was heading 2 hours away for work and started hearing a clicking from the engine and loss of RPMs, about 2-300 when the click happened, but no engine light or electrical issues like the first time. I called the same dealer that repaired it the first time, I know it was stupid, but was told if "no engine lights are on they cant take it in under warranty cause they cant get error codes". I went straight to Napa, tested for codes and had none. I went to the nearest GMC dealer which was in town and they immediately said it was not able to be driven. It is now sitting there waiting for parts that are on back order cause this seems to be a common problem with 2018 or newer trucks. LONG STORY SHORT, my family has had GMC since I can remember and they have lost a life long customer. I love the truck, but the effor GM is putting into solving the problem is none if any at all. They just warrenty it for 5 years of 60000k miles and act like they are doing us a service. I have yet to receive compensation for the time lost or answers from them about how they are solving the problem instead of just replacing defective parts with more defective parts.
