2007 Toyota Prius Owner Comments

Toyota has failed to recall the electric water pump in the second generation Prius. Toyota has recalled the first generation Prius for a faulty electrical water pump, which is the same pump found in the second generation. While driving home from work, my check engine light turned on and I had to go to the Toyota service to get it checked. After being told that it was recalled on the first generation, I looked up information online on if this was the same water pump. I then came across numerous articles and recalls on other Toyota websites (in different countries) stating that the pump has been recalled. Toyota however has not recalled any of these cars in the usa.

2007 Prius (69K miles). Driving on highway, all caution lights came on. Towed to dealer and diagnosed with a 12-volt battery issue. $280 to replace the batter. Three weeks later, same cautions lights. Got most to clear with a restart with the exception of the "master caution" and the "engine check" lights. Dealer showed code of "P0A93" and stated inverter coolant pump needed to be replaced for another $486. Check online shows Toyota knows about the pre-2006 issues and that many 2007 and beyond owners are running into the same issue at various miles.
