They're replacing my hybrid battery... 7-10 biz days to ship the battery, truck has to be down the duration.

That's actually good news.
@m_bt54 just had his replaced too. But I don't think his truck was down long. Pretty quick if I'm not mistaken.

2 days would be great, but I was supposed to head out of town tomorrow, and I'm fairly confident it won't be ready. So even if they wrapped it up by Saturday, I'm down until Tuesday when I'm back in town. But he did say 7-10 days. Since full breakdown last Sunday, that'll be 2 weeks of lost use at most now. Kind of a bummer...not gonna lie, though, I'm stoked at the idea of getting some pep back and the random/constant faults ceasing.

The dealer is setting up a rental, though, so I'm grateful for that.

FYI, new hybrid battery solved almost all the trucks issues.

However...it was in the shop for 3 months, unclear whether the dealer was fighting for warranty coverage or the part was backordered, as they'd say both when I called for updates.

The truck sat on the lot for so long that they also replaced my brand new 12v battery with the same factory Motorcraft battery that had given me tons of problems previously.

So no hybrid issues for 4 months and 20k miles since getting the truck back, however...my truck sat unused for 3 days over the holidays, and for the first 2 days of driving it again, I got generator fault warnings, trailer module faults, constant on/off flash and ding of a fault I couldn't see...but now, after 3 weeks of daily use again, they're all gone...

So the moral of the story is that these trucks can't be left unused for more than 2 days.

My truck frequently sits for a week or more and ever since doing the BMS reset, has never issued a low voltage warning, or any other problem.
