HELP!! 06 Prius stops accelerating, all warning lights on icluding hybrid system warning light

Sounds like hybrid battery problems.
At 120,000 miles the car has a lot of life left.
~$2600-$3,600 will get a New pack installed by a mechanic or dealership.
For a bit less you could buy the New pack from the dealer and install it yourself.
There is a wide range of Used batteries out there. You'll get what you pay for.
For $1600 you can buy non-Toyota New battery parts that you can assemble into a working pack.
There are even more options that if you want to buy diagnostic tools, chargers, and more and do a bunch of assembly and disassembly yourself on a regular basis.
Or sell it and move on.
Decisions, decisions.

 

I have an '07 which has had some issues. I just ordered Panlong BT OBD2 car diagnostic scanner and not sure what app I should get? Dr. Prius? I am clueless about what I'm doing! Help/suggestions would be appreciated!

 

Dr Prius may get you started.
Can read and clear error codes.
Can see battery data.
