A couple of things (folding mirrors and EVIC)

[dhay13]

My son has a 2021 2500 Cummins with factory power fold tow mirrors. He said today he went to fold them back out and his drivers side mirror kept going to fold backwards. He had to grab it with his hand to stop it.

Also, I know there are many that complain about the EVIC MPG readout. I have hand calculated every tank in my last 3 trucks and they are usually pretty close and sometimes higher than the EVIC. Filled it tonight and actual was 12.6 MPG while EVIC read 11.9. Happened bout 2 or 3 fillups ago too

I recall reading something recently
the discussion mentioned syncing the power folding mirrors

maybe someone will have a better answer
