2021 CHEVROLET SILVERADO 1500 Complaints

Rain is coming in through the back window. Dealer is stating that the rain is coming from the sliding window but satellite is stating it’s the brake light on the top of the truck.

I purchased this vehicle brand new is 2021 with the 6.2 liter engine. I have had all the regular maintenance performed as scheduled with 90% being done at a Chevrolet dealership. My truck has around 90,000 miles on it and now the engine is out. It started with showing low oil at 50% oil life left. When I took it to have it checked, it was 3 quarts low on oil. I did another oil change and was told I had to start an oil consumption test in order for them to review the issue. I had it checked every 1000 miles. The first and second check was fine. The third check was one quart low. They took it in and found that the spark plugs were oil fowled. Upon further investigation, they found that the cylinder walls were scored and had oil bypass in the cylinders. I have done everything right with this truck. Took care of it in all the ways I was supposed to. There is no reason what so ever for the engine to have gone out at 90,000 miles. There has to be more to this. I have looked it up and other people are having the same issue with the same engine. Why is nothing being done about this?

Transmission isssues hard shifting and no shifting at times. I informed the dealership about the recall on this issue and they are saying it doesn’t fall under the recall which isn’t true because my vehicles is showing all of the symptoms under the recall #N242454440.
