Rx400H Wont Start!

[akkeith]

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?

Thanks

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.

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.

My money is on it needing a new 12V battery...

Agree with everyone else. New 12 volt battery needed.
