  1. I bought my 2020 GMC AT4 back in early December. I took delivery up in Montana so my first drive was a 750 mile trip home. I have driven it very little since and it currently has about 1500 miles on it. I noticed the CEL on the other day so I plugged my ODB scanner into to reveal a Code P2002 Diesel Particulate Filter Efficiency Below Threshold. It was running fine, no other apparent symptoms. Read more at: https://www.obd-codes.com/p2002 I took it into the dealer two days ago. They called me later that afternoon and said that it was a new situation and that they were working with GM Engineers to determine a proper course of action but they would like to keep it overnight. I wasn't surprised, in fact I expect that out of a new power plant and I have a daily driver. Yesterday they let me know they were Fed-Exing an "exhaust pressure differential sensor" from Lansing. They said the truck was OK to drive and that I could pick it up if I wanted. I elected to wait until the repair was completed and hope to have it back today. I didn't see this code posted on the forum so I thought I would drop this information here for others to search. I will provide another update when I get the truck back. I will also ask what this would cost if it wasn't under warranty because I think that is useful information for evaluating the total cost of owning the LM2 diesel plant. I did get an extended warranty but cost/risk and warranty coverage will be a inevitably be a huge factor in deciding how long to keep this particular rig. I really really like driving it, more than the 6.2 and ALOT more than the 5.3. I haven't towed with it yet but I hope to try that out this weekend. WALLY
  2. https://gmauthority.com/blog/2020/08/2021-chevy-silverado-gmc-sierra-tow-ratings-incoming/ Pretty interesting. I'm not sure it sways my buying decision too much as 9000 is about my limit on a 1/2 ton truck anyway, but I'm glad to see any increase even if I'll probably never use it.
  3. I just picked mine up 2 weeks ago, I did have the 2.8 duramax but wanted more.
