2016 Hybrid System Malfunction, Failed Inverter? 116K miles

Anything can fail, but the usual cause of an inverter failure is connecting a 12v battery backwards when jumping the Pius or replacing the battery.

 

a reasonable mech can throw in a salvage inverter for a few hundred dollars.

but first, ask for the codes from the dealer, and post them here. this is a very unusual failure.

 

Thats horrible news. Like Bisco said maybe call around to a few other Prius repair shops or see if they can install a used inverter. The only thought I could think of is that there was an issue with the wires going into the inverter and there was a TSB for that where they taped them up to protect them from rubbing and failing.

 

If you live in California or other carb states it should be covered by the emission warrantee. Also I thought Toyota did 150,000 or 10 year warranty on hybrid system. I would check around.

 

If the car was bought in Calf, check out the Calf/CARB-States warranty:

I have a 2017 Prius Prime and received P0A1B94 today. I don't know what it means, but I cleared it, and I'm praying it doesn't come back. Any idea what it could be or what I should look out for? Prior to this I was dealing with a low 12V battery message and ended up fixing a brake booster that was leaking brake fluid.

 

Or maybe overheating? How's the inverter coolant or coolant pump doing?
