AGM batteries charge at a higher voltage which, if anything, would result in an overcharged flooded battery. That said I didn't notice any change in the voltages when switching between the two in the BMS settings.
The manual calls it out as a 99R battery; 140R might fit but it's 15mm taller...
Ford doesn't make an AGM 99R which makes the whole "they were supposed to be AGM" argument suspect. It could be true in the case of the EcoBoost where they did eventually switch to using AGM. I wouldn't necessarily take the battery type in the AB settings as definitive proof on it; mine also had...
Unlikely based on what? Only the Lincoln Corsair has the eAWD setup and that's because it's a PHEV which can't fit a driveshaft because of the significantly larger battery pack.
The system isn't "in AWD all the time"; it's able to clutch in and out as necessary. The Escape Hybrid has no significant mileage penalty (and manages to fit a driveshaft past the heat exchanger).
Likely wouldn't match up with the current upper bumper due to how it dips down in the middle.
Design-wise I think it's "okay". I don't quite like the big open patch the change in the headlight shape creates. Maybe it'd look better with that area blacked out.
The recall documentation to the dealer has billing labor times. (although book labor time doesn't strictly always follow actual time to complete, for better or worse)
The owner's letter is an estimate
There are no parts require for the Maverick.
Only 23 Escape/Corsair require parts because...
There aren't really individual patches just for that issue within the module so it's not like there's an install order. Rather they just update the module(s) affected to the latest firmware version.
As for the labor times, are you going by the labor hours in the Ford to Dealer documentation or...
The 'bad' 23E09 update programming should be phased out now that Ford has identified the cause (and has a separate recall to address those that received it).
There is an extra screw terminal on the hybrid's positive battery terminal. It's on the side, facing towards the rear of the vehicle. Kind of awkward to get at.
There's a number of modules that are still awake even if the vehicle isn't running. The BMS specifically tracking power used (or charged) while parked so it knows how many amp-hours the charging system needs to replenish early next start and then it can lower charge load for efficiency.
Flashing or not doesn't denote degree of seriousness. Flashing just indicates a cylinder actively misfiring. There are plenty of conditions that will set a solid CEL that can damage your engine.
