System shutdown
I am parked on the side of an interstate, awaiting a tow truck. When i accelerated to enter traffic, I got malfunction errors on virtually every system showing up on the display. Luckily I was able to get well off the highway, but does anybody know what might cause such a complete catastrophic failure?

It may be because of many reasons. One of them is the alternator.

Wow, I'm new to the Lexus ES350 family, so I would definitely be interested in hearing what caused that shutdown. I previously owned BMWs (4 in a row) and none ever left me stranded on the side of the road before...

Such failures, in my knowledge, are rare to Lexus. Did you buy yours pre-owned? Maybe check CarFax for a clue on if this unit has a history. Might also give you an idea where the problem is. I suppose every brand produces some units with a weakness for one problem or another.

My 2019 ES350 is certified/preowned and in warranty. As noted elsewhere on this thread, alternator failure is a frequent cause of multiple concurrent electrical systems shutting down. But I won’t know for sure until they do the diagnostic (in a couple more days). I will report back then.

WOW.
That's a great outcome, given the symptoms. Glad you found a relatively simple and inexpensive resolution

Good thing it didn't get past the throttle body into the intake runners and down into the valves. That would have been a mess to clean up. Would likely have jammed into a valve and then melted if the engine was at full temperature. Or worse, get into a cylinder.
The real question is - what the heck would have caused that to break? Did they charge you for the service?
