TOD...Triangle of death...(sigh)

How much oil did you have to add?

You would need to get the codes read, it could be something fairly minor like a failed inverter pump to something major like a failed hybrid battery

 

You can try for assist from Toyota USA on cost reduction for new batt, if it comes down to that. But you'd have to get the codes read by Toyota, and negotiate a little ...takes a little while for them to respond. You're over 10-yr warranty but you're in CA so that's a plus possibly worth a try.

 

If you're a DIYer, you could stop in a local auto shop parts store and have your OBD codes read. Most places will read the codes for free and then you can google to see what needs to be fixed.

If I was on the road with the same problems I'd take the car either to 1 - A hybrid specialty repair shop (google hybrid repairs in google maps, etc.) or 2 - A Toyota dealership. Most local auto shops aren't specialized in Prii, and therefore are more likely to make mistakes when repairing and leave you stranded longer.

 

First thing to do, get the codes read.

 

Dealership would read the codes for maybe $50~75. Likely they're the only ones that would get everything; other places with generic readers are not as successful? And best informed to propose a course of action.

 

Your oil was low enough that it might have been the cause of your warning lights.

 

From what I've heard here, by the time you get a low oil pressure warning light you're crazy low, virtually no oil. The distance between the two marks on the dipstick is something like 1.5 quarts, and I believe Toyota says anywhere in that zone is within spec.

 

I don't know if the warning lights will clear themselves with time. You could clear them by disconnecting the 12V battery for a minute which will clear nearly all codes. If there are serious other problems, the lights will return.

 

If you have the time, I can check the car for you. I'm 20 minutes west of Pomona.
