Hey guys! I just hit 226,500 miles on my 08 Prius. I bought it a few years ago at 208k for pretty cheap ($3k). Since then, I've replaced the brake actuator and the inverter coolant pump, gotten new tires and new tires sensors, done regular oil changes and filter replacements, etc. Mostly just regular maintenance. Recently, I had an issue with the car throwing some lights: (!), VSC, Check Engine. I had the codes pulled at Auto Zone and it was POA93, so I checked the coolant pump and it was fine. Motion in the reservoir and firm movement in the line. My coolant was low, however, so I added some more and bled the line & that seemed to fix the issue. I unplugged the battery to reset the lights and drove it for another 100 miles without any problems. My car actually seems to be running better than it has been in a while. However, A few days ago my check engine light came on again, along with the the warning light on the display, which I believe is the hybrid system warning light. I took it to the dealership today for a multi-point inspection because I know they can pull codes that Auto Zone can't, and boy was it a doozy. Here are the codes thrown: Hybrid: P0A93, ABS/VSC/TRAC: C0200, C0205, C1241, C1252, C1256, C1391 Tire Pressure Monitor: C2179 (I just had my sensors replaced last week by Discount Tire) Air Conditioner: B1421 (my AC has never performed well in the Texas heat, it's off & on and not consistent w/ cooling) It received a very expensive estimate, largely for things I've already replaced (brake actuator and hybrid system pump (which I'm assuming is the same as the inverter coolant pump located behind the driver's side headlight)). Here's what they suggested: Replace hybrid system pump Replace 12v battery ABS accumulator pump & booster replacement Brake fluid flash Other suggested maintenance was a wheel alignment (which can wait) and serpentine belt (which looks simple enough to replace on my own). Questions: 1. Is it possible the codes just weren't cleared from the replacements my dad and I did? (ABS system and Coolant Pump). Is there a reason why these codes would stay in the car's system? 2. Is it worth it to replace the 12v battery? Is it likely that this will have any affect on the car's performance? 3. Is it possible to check hybrid battery performance? I'm really needing this car to last another 2-3 years while I finish grad school, but I know the hybrid batteries usually don't last past 220k. I'm honestly surprised mine hasn't gone out yet. 4. Is it logical to look into selling my car for the KBB value ($1,500.00)? Would anyone buy it knowing it needs the maintenance above? Thanks in advance. You guys have always helped me out. Any advice is appreciated!
