Ok so dealer called, it’s one of the control modules. It needs the new module then has to be programmed to the truck, I should have it back tomorrow evening or Wednesday at the latest. I will post up exactly what the service ticket says, really glad it’s not the battery.

Ok, is this from personal experience? Is this common with these vehicles? I hope this isn’t the case. Guess we will see. Thanks for the vote of confidence, lol.

Ok well I have to start somewhere. I have to give the dealer a chance. If it goes down that road they can keep the darn thing, if it’s that complicated (which it shouldn’t be) I’ll jump ship. I’m not willing to spend a bunch of money to guess on anything.

Ok so the invoice says internal failure in serial data gateway module causing b1000-39 DTC.
Serial data gateway module replaced.

I cant seem to find a b1000-39 DTC. Drove the car this afternoon, it’s holding in auto stop mode longer again and accelerates a bit longer in electric mode. Not a large sample size, but fingers crossed.

I had some other stuff done while it was in, IIRC $500-700 range.
