Prime Shutdown

In the olden days I'd say it was a dirty fuel filter but now a days ??
Get the codes read or read them yourself.
May give some insight into whats wrong.

 

if you are talking about the humongous screen rebooting, yes. search is your friend.

if you are talking about the engine, that's how hybrids are designed to operate.

if you are talking about the whole car shutting down and stopping in the middle of the road, get thee to a dealer

 

I like the “That is the way hybrids work “ solution. I was reading more into the question than required.
Occam’s Razor.

 

Intermittent malfunctions can be a royal pain to figure out. But, if they read the DTC codes, I would think there would be a history of some kind of trouble code. It's odd to just shut itself down and way more odder that it then restart itself.

 

also, if the car shut down, corporate can bring their computer and see that info in the 'black box'. give customer service a call, and report your experience to nhtsa, that is a dangerous situation, and needs to be addressed before someone is seriously hurt.

 

When you return to the dealer, ask them to check not only for diagnostic trouble codes (using the Health Check feature of a Toyota Techstream diagnostic system), but also for vehicle control history events, described in my previous posting. If the dealer is stumped, the should open a case with Toyota’s Technical Assistance System (TAS), the dealer-only support line.

 

do you know if this is upgrade something we are aware of?

 

I haven’t seen a service bulletin or campaign publication from Toyota about it, if that’s what you mean.

 

Yes, thank you

 

Yes. Just over 2000mile on my prime. Scary. Still at dealer. I won’t drive it until they find what caused everything to black out. Scary.

 

Did it work?

 

Yes! Scary
