Good morning folks,
Looked around a while but not coming up with anything related.. 2019 is300 f-sport that has an intermittent (seemingly random) issue where you go to fire up the car and get a ton of malfunction errors.
I don't know if I got them all, but the list below:

blind spot monitor malfunction
pre-collision ssytem
front camera
lane departure alert
antilock brakes system
power steering
braking power low

The speedometer doesn't read, just about every warning light is on, power steering doesnt work, but otherwise, driving doesn't feel impacted.

Everything works perfectly fine before or after. Last 2 times this has come up, it just went away after a couple of restarts. Doesn't seem related to pulling battery or not.
All systems can't have failed at the same time. It feels like there is some module that just isn't kicking on.. has anyone dealt with anything like that?

 

This is probably going to end up being the battery...

 

I have twice experienced a near-catastrophic electronic system failure. For the most recent (5/17/25) I was able to drive (with great difficulty) the car to the dealer. The 1st episode (8/29/24) required a tow truck.
Error messages displayed (both times):
Power Steering Malfunction
Headlight System Malfunction
Pre-collision System malfunction
Front Camera unavailable
Lane Departure Alert malfunction

the 1st episode began with a Malfunction in the LED Headlight System on 8/15/24 which was fixed for $2,600.
