Hello, My dad bought a 2007 prius new in April of that year and gave it to me about 3 months ago. He took great care of it and even had a 110 point inspection before he'd let us have it to check it out. Two weeks ago we received some errors and took it to the only local Toyota dealer around us (Springfield, MO). The parts that failed: Hybrid battery pack - $3,086 Normal battery - $207 Coolant control valve - $468 After tax and two small things I can do myself, the total is $4,100. Kelly blue book puts it around $4,300 with everything in very good condition, which it isn't. What would be your advice? Keep or sell. Thank you for any/all the help. And I will continue to scour ft he forums for old posts. Geremy
How many miles you got on it? You want a new Toyota batt if possible. You may want to ask Toyota for assist as follows: HV Battery Goodwill Warranty Listing - Toyota Prius USA | PriusChat
well thats some good miles you could still give Toyota a try. If you want to buy a new Prius that's another way to wiggle a free batt fix from Toyota (possible) Not familiar with the cooolant valve issue but sometimes pump needs replaced.
Geremy, I just went through a similar situation. I have 2007 Prius which I purchased new and took good care of. I was driving along and my car's warning lights all went on and I found out that the inverter converter went bad. I have 84k mileage, $4200 plus it killed my 12volt battery at $345 plus $900 in labor. The blue book value was about $4000 and the trade in was as much $6500. I must admit in 8 years, my Prius was never in the shop for anything except for general maintenance. That is pretty great and I had to accept that many cars over that time period would have had exceeded that price easily. I lucked out because I called Toyota customer care and they generously paid for the replacement cost of $4000 for the inverter. i know through the forum that these cars last well into 150k-200k mileage. Even for a year or two for a small investment of fixing them $4000 is cheaper than one year of payments. Of course you may consider a new car will have a 3 year warranty but will cost you $28k. I think you'll find it more economical to invest in fixing it up, saving the additional money for two years+ and getting a new car. My car is paid for and that is why I took the repair cost. I'm very happy with my Prius and Toyota came through in the clutch with a major part replacement.
just went through all those codes on my 2005 with 176,000 miles, rebuilt the battery myself (still failed within 2 weeks) I got Advanced auto to price match the Optima Yellow top with an on line retailer for $149 + tax, after replacing the 12 volt my digital dash was intermittent and started getting the coolant valve code as well, I sold mine as it was becoming hard to rely on for basic transportation..sell it for 1500 just list the problems and be sure they transfer title out of your name..gas is cheap Hybrids are not that desirable now but stick with Toyota for quality
Wow, thank you all very much for the replys. We're going to replace the 12v battery and the coolant valve. Would the coolant valve not working correctly cause the hybrid battery to get too hot and start failing?
No faulty coolant control valve will can only cause the heater to not work and fault light to be on. Hybrid battery is air cooled. Fan for the hybrid battery can get full of hair or something similar and cause hybrid battery to overheat.
No, the coolant valve is in the engine coolant loop and the Inverter coolant loop cools the power electronics and the tranny. The HV battery is ai cooled by a fan that sometimes will get clogged with fibers at the inlet at the top right of the rear passenger seat. The coolant valve will sometimes stick if no coolant gets to it (the coolant acts as a lubricant). This can either be due to a low engine coolant level or an air bubble in the coolant loop. Try adding coolant and see if the valve code goes away (it did for me). JeffD
Sweet, resent my email to the dealer to just change the 12v battery. I'll grab some coolant on the way home tomorrow if the car dash still shows an error. It's not like we really need the car to heat much as we're heading into an early summer. Mid Missouri and 60s all week. Thank you again!
You need the Toyota PINK super long life coolant or equivalent clone. Yes could be low fluid as the water pump sometimes leaks on a Gen2. I have the orig water pump but it went thru a period of leaking and then it held firm.
