akkeith Posted October 25, 2010 Share Posted October 25, 2010 My wifes 2008 RX400H wont start at times. For example it would not start last night so she got a ride home then the next morning we went to get it and it started. It has done this several times over a year now where sometimes it will start if left for awhile or if I jump it or if I put a charger on the battery. Any ideas whats up?

lwleedy Posted October 25, 2010 Share Posted October 25, 2010 Had this happen to my wife's and mine. Weak Battery was the cause on both. Charging helped my wife's and had the battery replaced under warranty on mine. Lenny Quote Link to comment Share on other sites More sharing options...
RX400h Posted October 25, 2010 Share Posted October 25, 2010 I agree. You might want to have the dealership test the 12V battery. This is the time of year when a weak battery will show signs of immenent failure. Quote Link to comment Share on other sites More sharing options...
SW03ES Posted October 25, 2010 Share Posted October 25, 2010 My money is on it needing a new 12V battery... Quote Link to comment Share on other sites More sharing options...
