GM has really dropped the ball with the launch of the T1 HD platform. The bulk of the issues are around part failures at least and not the craftsmanship of the workforce. GM is building these trucks around the clock and its a struggle for suppliers to maintain the inventory levels needed for production let alone repair parts. My 2020 has had one problem after the next. New computer module, new brakes front and rear, steering shaft, leaking transfer case seal, replaced battery, misaligned from the factory and multiple electronics issues that are uncorrected. My dealer is working with me to get me out of it and into an identical '21. The problem I am having now is that the new truck arrived last Tuesday at the dealership along with several others that had already been sold but GM has yet to send them the MSO paperwork which is required for the sale and title. I got a text about an hour ago that they weren't in todays mail either. So the trucks sit there until the papers arrive.
