Thanks for using Just Answer for your question!

 

Have you had a repair shop look at this concern yet?

 

Is the Hybrid battery original? If yes, how many miles are on this Prius?

going to bed now have to get up at 5am and go to work.

We have seen several of these Prius with The codes you have...

 

P3105 Battery ECU Communication Circuit Malfunction

 

P3002 HV ECU Communication Malfunction

 

The 2 that I had required the replacement of the Hybrid Battery and the HV ECU located next to the hybrid battery. In both instances, Toyota paid for the Battery and ECU while the customers paid the labor to install the two items. It may be worth a try to talk to approach you local Dealer and see.

The warranty for the car is 5yr/60,000 miles but the Hybrid system is 8yr/100,000 miles.

charged new battery fully today and car started up was able to clear codes and drove it a bit, but don't know if the error will reappear. will it stay in the memory even after cleared for dealer to see it?

No, once you clear the computers memory, the information is gone. You can leave it for them to test drive and duplicate the concern.

Do you think I have a chance of getting them to warrantee it since it has 170,000 miles on it?

Not unless you are a very good customer of theirs, as in you have bought your cars from them and have had them serviced there. If you haven't done this, then you really aren't a customer of theirs and they have no reason to go to bat for you with Toyota.
