Ran into an interesting problem with my 2018 Sport. The parking lamps and taillights no longer flashed when I locked the truck. The remote start would no longer work. I had just had the AC condenser and filter replaced, apparently a common problem on the G2 and noticed the issues after I had the vehicle back. Turns out there is a small rather hidden electrical connector on the hood latch that had been left disconnected after the AC work. Mechanic knew right where to look when the service advisor told him the truck had had the condenser work. I spent hours perusing the manual trying to see if I or the dealer had inadvertently reprogrammed something. Hope this saves somebody some time.
