In December I experienced a disabling failure of my 2007 400h. When I tried to start it, the cooling fan came on at high speed as well as a host of warning lights. The vehicle had to be towed to a Lexus dealer. They had never encountered this problem before. Eventually they determined that a relay had failed that prevented power getting to the hybrid system. Has anyone else experienced this problem? Were there any additional consequences? It has certainly shaken my faith in Lexus.
Also, since the event occurred I have noticed that my hybrid battery no longer fully charges. The battery display never indicates more than 6 out of 8 bars. I start at the top of a long hill with 6 bars, and it still shows 6 bars at the bottom of the hill.
