Ive got a 2022 AT4 2500 that is just a few days from being on the ground, and I am seriously having 2nd thoughts. Every single thing I find on this GM platform is a nightmare or horror story. More people than not have them back in the shop within days of delivery for major issues, from transmission slipping to injector codes to electrical malfunctions. With GM being of no real assistance whatsoever. And forget about lifting one...every dealership south of Canada will do their best to void your warranty with all these issues going on. I am literally one phone call away tomorrow morning from backing out and telling them to keep my deposit. Ide be a lunatic if I buy an 80k heavy duty rig that is in the shop for 8 months out of the first year of owning it like most people ive heard of. It seems the vast majority of new owners are in the same situation. Which is barely getting it off the lot before it starts throwing codes and trying to buck them out of the seat. If I could get just 5 out of 10 people to tell me its worth the purchase, I would probably go ahead and give it a chance. But ive never been this on the fence about a brand new f'ng truck and im willing to bet finding 50% of new owners that say getting this rig is a good idea is a long shot.
