I have 2017 Sierra SLT with the 8 speed transmission that has 38500 on the odometer so bumper to bumper is over but the powertrain warranty is there. Last week the CEL came on after a hard shift when accelerating from a stop. Took it to the dealership where they scanned the computer and came back with a P0797 code. The paperwork states "P0797 stored in TCM as history, found update in TCM for false codes, programmed TCM and performed fast learn adapt." To me that says the terrible 8 speed programing was the cause of my CEL coming on. My issue is that the dealership is charging $100 for the service to reprogram the computer. My service advisor stated that GM does not consider that work to be part of the powertrain warranty. I expressed how I think that is a little BS to charge a customer for something the GM should be covering under warranty. Am I wrong and overreacting on thi or should GM have picked up the bill?

My 2014 and my 2017 suffer from this. I think it is finding the sweet spot but I do notice it on certain pumps more than others. Its like when there is a longer nozel there seems to be an issue. I just pull it out an inch or so and then I'm all good.

Well my MX4 was delivered yesterday and the only damage I can see on it is where during a previous shipping it was scratched. The panel that is scratched is on the bottom so I'll never see it. Unfortunately it has been raining since about 10 minutes before it was delivered which sucks cause it Would have been a nice rain to test out how water tight the cover is.

Well I ended up picking up a used BAK MX4 off of amazon from a reputable dealer. They say it's like new but could have a few small scratches on it. It was $611 so I rolled the dice and will see what it is like when it gets here. Worst case I can always return it.

Do you have any rub? I have been looking at that exact set up for my truck.
