Thanks for the replies!

The batteries seemed weak after I got it home. I figured it could be from sitting at the side of the road with the hazards and dome lights on for an hour or so. Had them on a battery tender since Saturday evening. It indicated a complete charge yesterday afternoon, I disconnected it when I was getting codes and it has yet to get back to the 80% charge indication. I checked the batteries back in the spring and they were fine. I will check specific gravity, water and load again this morning.

Could weak batteries cause these issues? When I see other posts on bad batteries, it looks like the batteries and sometimes the alternators are the only problems.

I have had the truck for 44000 miles and less than 5 years. 5 year powertrain warranty should cover this?? ... Unless it is batteries. If the batteries look bad when I check them this morning I will swap them out and see where it's at.

Thanks!
