2025 GMC Sierra 1500: The Ultimate Pickup Truck Review

[@10drowsy]

I've got a 2021 GMC 1500 X.31 with V8 5.3L & 4x4/AWD 8 speed transmission. Luckily it was made during Covid and its Computer chips shortage years. Thus, it has: NO engine Auto Start/Stop, NO AFM/DFM (which creates stuck lifters - 0uch!), NO down Hill Engine Braking (which is hard on transmissions) and NO On-Star system. Yes. All the "advanced" computer stuff that causes known problems. Instead of "more" electronics and better outer looks GM needs to go back to the base build - that creates less future problems. Especially its factory AFM system - that creates lifter and cam shaft problems.
