I have a 2015 GMC Sierra 5.3. I bought new. so far have only done oil changes and replaced a leaking AC Condenser and replaced dead battery.
what all should have been done or needs to be done at 100k mile service?
other than AC and battery the only issue i have had is on star/remote start from cell quit working but replacing battery reset that and its worked since then and the passenger window will stop working randomly. the first time it didn't work for 4 months then just started working again and now its just random if it does work or not. when it stops working it clicks at door just doesn't do anything. then another day it will work fine.
