May be a typo, but 3.0 duramax with 174k

Jeeze its a 2021 ! No way that could be correct. I have seen some people pack on big miles but 174K in a year?? LOL 


Hey whenever you see high mileage 3.0's please post them up. Its been out since 2018 but I dont see many high mileage ones. I love this motor so far, and would do it again tomorrow. Seems too good to be true sometimes.  I am sure it may have a couple of weak points just like every LS and LT known motor issues I have experienced in the past. But all of those known issues popped up pretty soon. Certian years, certain months with certain issues. Lifters, needle bearings from rocker arms, torque converters, transmissions, dropped valves(LS7), A/C condensers....I have experienced all of these.  They were all known issues and design flaws or bad parts. Can't believe I still buy GM. But this 3.0 has been remarkable in totality. Some rear seals, many crank no start (now resolved with TSB) some small issues as with any vehicle but no big flaw? We shall see, but uncommonly good...especially for GM!!
