�takata recall � I believe there is a major problem with Toyota Prius v they make it only for five years, they stop making it after 2016 because they realize there is so much problems in the engine, many car this model the engine get in fires, head gasket had to be replaced at 125,000 mile. Hybrid battery it go bad at 120,000 miles where is most Prius hybrid battery go for 250,000 mile minimum. My Prius be in gin GA on fire because there is a piece of metal from the engine fell down in the engin block and the engine break down with a big hole and most of the engine oil came down in to the muffler and my car got on fire. And that's happened I was driving on the freeway and there is no check engine light came on as a warning when that piece of metal from the valve lifter I believe fill down in to the block.
