Wow, tons of great information on this site! I just purchased a 2015 LTZ Z71 LML, 2500HD. :woott: Looking to learn a few things. Is there anything I need to do to Bulletproof this truck??? Any known issues that I should address as preventative maintenance???
Another new guy.......

welcome! As i have no clue what it's like buying a new one ill let other chime in ! But at very least, run fuel additive for your cp4 as the ULSD is lacking in lube
Welcome! As far as I know the LML is pretty bullet proof stock. You can always add a lift pump for filtration. The LML guys on the forum would know more about common problems than I would.
Thanks Veikra and Nathan, I did a lot of research before I bought this, my first Duramax, and they seem pretty solid. :thumb: I will be adding some fuel additive for lube. Got the 100,000 mile bumper to bumper so I won't be doing anything to void that warranty for a while! :woott::woott::woott:
Welcome! Wise choice. All around i'd say! Keep the warranty, keep happy.
