Some times it takes three tries before it stays running. My first thought was a bad battery in the car or key fob. Thanks for providing the TSIB, for this is definitely what I'm experiencing; planning to head over to the dealership with the thought that my extended warranty should cover it.

Precisely what I experienced. I went to the dealership. They wanted me to wait "and see!" Then I wrote Lexus USA, siting the following: Lexus bulletin: L-SB-0161-08, released on November 11, 2008. This internal Lexus bulletin addresses this problem, but so far Lexus has chosen to not publicize it. They responed to me that they would take care of it. They spoke to the local dealership and everything was taken care of. Remember, my warranty had run out when this happened. Good luck. Victor Pavamani

Hi everyone, I'm a first time poster. This forum is very, very good.
My '06 IS350 with 78k miles has this issue. Tom Wood Lexus in Indianapolis charged me $1300 to replace the starter instead of just replacing the ignition switch under this TSB about 10 months ago when the car had about 70k miles on it. Do you think 1) Lexus will fix the switch for free even though I'm out of warranty and 2) will I be successful when asking Lexus Corp to refund the $1300 starter repair cost when it was working fine?
Thanks!

anyone have information on how to remove the starter button and replace it? That PDF above links to something I can't get to. I think this is going on with my wife's car.

I am sorry I only have the guide for the '13 but hopefully it will help get you started in the right direction. The PDF should be attached to this post.

Its almost as if the car doesn't sense I am pressing the brake pedal any longer and then the security feature shuts off the car. This doesn't happen all the time, and wouldn't you know it, it never happens at the dealership. I thought it tended to happen when the its hot outside after being parked in the sun all day, but it has also happened to me first thing in the morning while being parked in a cool garage all night....

When this does happen it takes like 2 or 3 attempts and then it works fine. And after a successful startup, if I stop the car and then try to make it do it again, it won't happen and it won't happen all day or even a couple of days. But every now and then it happens....

Any thoughts or similar experiences?

thanks
i had this same exact problem on a 2010 infiniti fx35 and they couldn't figure it out, they just kept replacing the battery which didn't help, finally after speaking to consumer affairs they sent out the regional tech and i showed him a video and he instantly claimed he knew what it was...he told me the grounds needed to be cleaned, they kept the car for the day, did the job and from that day till about a month later it didn't happen, finally it did....never sent that guy out again but what i noticed was if i were to start the car and mash the gas it would start as it should, still don't know what it was up to now though
