Intermittent No Start Due to Failed "Push Start" Switch on Lexus LS460

An intermittent no start condition may be caused by a failed "Push Start" switch. Replacing the failed switch should correct this concern.

I will push the brake, green light comes on, I will push the starter button and nothing, sometimes it doesn't start until the 3rd or 4th time. I have replaced the battery in both the car and the FOB, still not fixed. In shop now for a diagnostic.

I live in Columbia S.C.it gets very hot here in summer months. My car has developed the same ignition problem I had in 2012. It starts then dies. It startsd then dies. This cn go on and on. It doesn't happen all the time. It is intermitant but seems to happen most on very hot days.Lexus replaced the push button ignition switch in July 2012, warranty. Now July 2015,it has the exact same problem! It seems to me that the ignition switch is "heat" defective. How can this same prblem happen to me twice? Now they want me to pay $600 to replace it!

had to purchase new push button starter - $600
I had the same problem I was pushing the start button too hard I was starting it and killing it at the same time. Now all I do is barely push the start button. Try it. It worked for me.
