The truck is scheduled for maintenance
I've developed warped front rotors and it's not gonna get any better so I've scheduled the truck into the shop for Tuesday. I'm also having them look at the fuel gauge. Lately, when I fill up, everything resets except the fuel gauge. It moves up to about a quarter tank and stops. Re-starting the truck doesn't seem to help either. About three starts later, the gauge functions normally again until the next fill.
So....Tuesday I drop off the truck and pick up the loaner and we'll see what I get back.
