I installed a Speed Turtle 3.0 on my 2020 GMC 2500 Sierra HD a couple of years ago, while it was still under warranty. After a while, the HVAC control cluster went dark. I could still control the heat and A/C via the touchscreen, but not the controls below. Removed the speed turtle because I knew it would cause a warranty red flag. Didn't re-install it for a long time. Now main warranty on truck is over and I tried re-installing it. Everything was fine and all lights checked out as they had before. Shut off truck and could not restart the truck. Removed the speed turtle and truck started fine. No more Speed Turtle for this guy.
