I have a 2025 GMC Sierra 2500HD with Duramax. Truck only has little over 500 miles on it and only had it for week or so. I'm getting check engine light and its giving code U1962 showing with it. Has anybody experienced this? I have appointment with dealer to get it in, but shouldn't be having this with only 500 miles on it. Very frustrating.

  Gen 6 V8 will have AFM and or DFM. The first engine detailed of this is the LS6 which is confirmed to have AFM from the Corvette Museum Bash sessions.

  I've heard of a scam screw on a gas pump (holds the credit card transaction by not allowing the shutoff lever to be fully seated) but I'm not sure what a "fake" scam screw is.

  Exterior and interior, not impressed. That dash is just plain lazy, no effort in design.
