Well time will tell because I pulled the trigger on a 2026. I won't have it past the warranty so other than the inconvenience I am not that concerned at this point.
No flaming as I am complete newbie but was literally about to pull the trigger on a 26 Sierra with 6.2 when a friend sent me a YT video from some guy Donslife that had all kinds of issues about the 6.2 and potential motor failure.
Very familiar with forums and how issues usually get more attention than the good but is this truly a concern? Really want the 6.2L with MAX TOW and was going between the Diesel and that one but really don't want to mess with DEF.
