That sounds frustrating. You will need to get your car scanned using a scan tool that communicates well with a Prius. This will identify the diagnostic trouble codes (DTCs) that you can use to begin your diagnosis.

You can start by getting the 12v battery tested (that's the small one in the back) and making sure that it has at least 75% charge. Ensure that you check all the fuses; including those on the inside as well. Toyota has issued a technical service bulletin (TSB # EL002-05) that addresses a similar known issue and it may apply to your car.

It is recommended that you get a certified technician, such as one from YourMechanic, to inspect your Prius and determine the cause of the problem. You can also contact the YourMechanic Customer Service desk at 1-888-341-3994.
