A full Christmas Tree!! All warning lights on. Honda Odyssey 2018. (Now Fixed - see description)

All the warning lights came on, but the car still drove. So what's up?
The internet said maybe a bad battery. Maybe a loose wiring harness. I booked an appointment to have Honda look at the problem.
Back from the dealership. I had the software update for the instrument display, and new display unit that were part of a recall.
What's interesting is the technician said the reason all warning lights appeared because there was "contaminants in the fuel injectors" that lead to the computer fault system kicking in with all the warnings.
I don't really know how a fuel injection problem can make the computer think the power steering has a problem etc... but they replaced the fuel injection system and this seems to have also fixed the issue.
The vehicle is still under warranty so it didn't cost me a dime.
Not sure if this helps anyone with the same problem, but also after the software update my android auto works perfectly (wouldn't connect in the past).
