GS 450h

  • 230,000 miles


My 2007 Lexus gs450H is not having all cylinders firing and has engine power loss. I called our local Lexus dealer and they said there's no recall of this kind of problem. I searched online and there's a certain recall describing exactly what my car is doing. The recall number is 10V309000- Toyota recalls 2006-2008 Lexus models due to possible engine problems due to micro-foreign objects in the valve spring that can cause it to break. This could cause the engine to fail suddenly, while the vehicle is in motion, increasing the risk of a crash.
