well i just traded my 2015 2500 dmax for a 2023 Chevy 1500 3.0 d max and it has got a hole 26 miles on it and it is setting at the service dealer with needing a DEF tank with a national back order. I do got a gas loaner from the dealer ship. Thank god. Now there no time frame on repair. it makes you want to pull your hair out. I am wondering if anyone has got there's repaired ? time frame? and have they had anymore problems?
