There's the CarABC and Dasaita options, but they're reported a bit quirky what with being essentially a sort of tablet running it's own OS bootstrapped to interfacing with the stock Sync system.

It was less about demonstrating the capability than leveraging that it gave them extra CARB emissions credits as "fast refueling Zero Emissions Vehicle" capable. The regulations were later changed so that they only got the credit if they actually did have the battery swaps on record and then...
You never received any info on this because it's a CSP, not a recall. A CSP is just a manufacturer extended repair coverage related to a specific component/fault if it occurs and doesn't have the compulsory notification requirements of a federal safety recall.
I stand by my opinion that the rust issue of drop-ins is overblown especially anywhere that salt exposure is a factor. The bed is going to rust out faster from the underside faster than from some boogeyman trapped moisture.
Unless it's a drive-over pit quick lube place, a service manager who doesn't have the oil jockeys doing a basic grab and shake test of the front end or visually assessing brakes, leaking shocks, etc. is doing a bad job at generating any follow-up business. There's a reason that oil changes, etc...
The big rub there is that 30% hit in the eyes of any insurance company, regardless of what you actually pay for the vehicle. It means the value is going to be that much lower in determining if it gets declared totaled and the payout in the case that it does.
I wonder if their "alignment" is just they have one of those vehicle scanner systems on intake that measures some alignment parameters, tire tread, and records the vehicle exterior for damage.
Personally I don't like the mostly straight siping on the Outpost APT versus a zig-zag sipe for more bite into ice if one wanted to use it as an "all-weather AT".
Consequently when the Rotiivas on our work plow truck needed replacing (another downside of the Nokians is they get considerable dry...
It was a bit of a light winter here this year so can't speak to them in particularly heavy snow, but I switched to a set of GT Radial MaxClimate all-weather tires in January and they've done good so far. Fairly inexpensive and made in the US.
The DC-DC converter doesn't work as an intermediary between the drive motor and HVB at all like you describe. It's simply an accessory to the HV system that steps down to "12v" (13.6-15.2v).
Do you have a base Lariat or a Lariat w/ Luxury Package and the B&O system? If you look behind the rear seat passenger side is there a silver module box and subwoofer?
Some of that wiring, especially the wad of connectors wrapped in tape and the module, are aftermarket. 99% a brake light logic module for the light in your topper.
The ignition switch sequence doesn't do any learning on its own, but puts the system in training mode (announced by the horn honking) that you then would follow up with either using an activation tool or adding/removing air starting at the LF and moving clockwise. FORScan should be able to...
