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.

had to purchase new push button starter - $600
Car will not start after parking and come back from shopping on hot days. Some times it takes 5 to 6 trials and some time I have to wait for 10 minutes and retry. I took it to dealer and they say they can not duplicate the problem It is frustrating to know that dealer will not admit that other lexus owners have the similar problem.

Having ignition/satrting problems. Has not been corrected.
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.

I live in Columbia 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!
