Subaru integration misassigns data between cars

[nanobra1n]

The problem

I have 2 Subaru cars (one Outback and one Crosstrek, different MySubaru accounts). I just added the Crosstrek to HA and now data downloaded from the Crosstrek (avg. Mileage, Range, Odometer, tire pressures & Position) get assigned to the Outback. Reloading the integration fixes sensor values temporarily, but location history remains messed up.

What version of Home Assistant Core has the issue?

core-2024.1.6

I think I might found something, but I'll look into this tomorrow

@nanobra1n I just submitted a PR (#114119) to enhance the device diagnostics to provide more verbose/raw information as it is received from the Subaru servers. Once that is merged, and you are able to send new diagnostics output, it might help me pinpoint the issue.

Until then, one possible workaround would be to temporarily share access to one of your cars to the MySubaru account for the other car. Multiple cars in a single account is known to work, and you can revoke the shared access once this issue is resolved.

@nanobra1n the PR has been merged, so I can look into this now. Please send your device diagnostics for both vehicles.
