On may 16, 2015, while driving my second-generation 2007 Toyota Prius on the freeway, I experienced a sudden loss of power, along with the illumination on the instrument panel of the malfunction indicator light, master warning light and hybrid warning light. I was able to maneuver the car to the side of the road and summon emergency help. A nearby Toyota dealership replaced the hybrid inverter water pump, which fixed the problem. However, the dealership did not advise me of a safety recall. Toyota customer experience center today stated that the original hybrid inverter water pump was replaced on April 7, 2011, under Toyota limited service notice a0n; hence, Toyota refused my phone request for reimbursement of my may, 2015, repair expense. The 2011 "a0n" replacement pump appears to have failed by the same failure mechanism leading to recall campaign "c0u", which is different from the a0n failure mechanism.
While driving on the freeway, suddenly noticed slight jolt and illumination of various warning lights in the instrument panel (check engine, large warning sign, emergency car danger sign, vsc sign). Hybrid system ceased functioning, leading the the car to drive using gasoline engine only. Dealership determined hybrid electric water pump was no longer functioning, needed replacement at cost of $570.

The vehicle was taken to an independent mechanic where it was diagnosed that the water pump needed to be repaired. The contact stated that the water pump was repaired previously under a manufacturer's recall. The manufacturer was notified of the failure. The approximate failure mileage was 121,568.
For a long time my Prius has had pauses in acceleration occassionally when leaving a stopped position. You press on the gas and there is a couple of second pause before it accelerates. You have to be careful when pulling out into traffic because when it looks like you have time to go, with the pause it is no longer safe to pull out. I call it stalling out. There is a recall for Prius that began on January 17,2013. It states: the corroded wire may break and the water pump could stop. It could cause a short circuit between coil wires and a possible open fuse, creating a stall like condition. The remedy is that Toyota will replace the electric water pump at no charge. I have the stall like condition and during my last service at a Toyota dealership he told me I needed a new water pump. I contacted Toyota about my problem and the recall. They responded that my vehicle was not involved in the recall and they would offer me no assistance in the $500 payment for the water pump. I believe my vehicle has the problems listed in the recall and should be included.
