New to Prius - Brakes, VSC, Check Engine, Master Warning all came on without warning

Hello all,

I'm new to the Prius having purchased my car in January of this year. The car in question is a 2008 Base with 117,000 miles. The oil was changed when I purchased the car and I've only driven around 3,000 miles so it has not been changed since.

This morning when I turned on my Prius the Brakes System ((!)), VSC, check engine, and master warning lights all came on at once! The only issue I've had was a dead 12V back in March which was promptly replaced. I moved the car to a different spot in the driveway, let it sit and hour, and tried again only to see the same warning lights.

I have an appointment with my mechanic scheduled for next week. Otherwise I know nothing about Prius' and have no direction as to what's wrong with my car and what needs to be done to find out and make it roadworthy.

Any help at all would be appreciated. Thank you!

 

Hey guys, thank you all for the advise!

I took the car to the shop and the battery tested just fine. However, when they tested the computer the screen lit up with error codes:

P0A80 - Replace Hybrid Battery Pack
P3013 - Battery Block 3 becomes weak
P3000 - Battery Control System
C1241 - Too Low of Too High Battery Volts
C1242 - Open Circuit in Ignition 1/ Ignition 2 Cell
C1259 - HV System Regenerative Fault
C1310 - Fault in HV System / Fault in ACTV Brake Booster Solenoid
C1378 - Capacitor Communication Circuit Malfunction
C1532 - ECU Malfunction
B1462 - Humidity Sensor Circuit Malfunction
B1412 - Ambient Temperature Censor Circuit
B1443 - Air outlet damper control servomotor Circuit
C2122 - Transmitter ID2 Nor Received (Main)
B1790 - Airbag Sensor assembly ECU Communication Circuit malfuntion
B1650 - Occupant Classification System Fault
B1660 - P Seat Airbag ACTV Indicator Fault

To my eyes this seems very overwhelming and I have no idea what to do. My mechanic said he things most if not all of those problems would be solved by replacing the hybrid battery, but he is not able to do so. How do I find a reputable Prius mechanic in Phoenix, AZ? Is there a directory of trusted mechanics on Priuschat? Also, how much would this all cost? Any help whatsoever appreciated! Thank you!!

 

Thank you for the advice! I'll make a new post looking for a mechanic in Phoenix

 

Update: Hybrid battery was replaced with a "New Prius Batteries" kit, 10 months ago.

Fitting the new hybrid battery cells was not too difficult. Testing the old cells after removal revealed two of the cell blocks had failed causing the aforementioned error codes. The new hybrid battery solved all the vehicle's problems, and the car gained about 6mpg to boot!

For others facing problems similar to mine, it's time to either replaced failed cells or the hybrid battery all together.

*Note: For those who are mechanically inclined replacing the hybrid battery is a straightforward, if tedious, operation. WEAR PROPER SAFETY EQUIPMENT!!!!! I use to work on High Voltage circuits and the current running through a Prius is enough to kill. Insulated gloves are around $100 but they can save your life, a far more valuable asset. All in all, it was worth it and when it comes time for my other Prius to get a new hybrid battery, I will purchase from New Prius Batteries again.
