I'm new to the forum and new to Lexus. I sold my 04 4Runner and bought a 2014 RX AWD with 15K miles in January. I love the vehicle but four times in the last month it wouldn't start. Foot on the brake , press the button and nothing happened. The seat and steering wheel went to my settings though. I waited a minute or two and tried again and it started. I know that it's still under warranty but I' wondering if anyone else has had this issue? I did as search but did not get any meaningful results. Thanks for your input.

 

I noticed this with our 2015 RX450h and finally realized that I was trying to start it a bit too quick. Works fine if I wait a couple extra seconds before pushing the Start button after putting foot on the brake.

 

agree with litzdog ^^^^^^^ also the color on the push start button i think changes color to orange when it senses everything.

 

Thaks for your input. I'll start by changing the remote batteries.

 

Over the last few days, i've checked mine, and i can start it within 1/2 second after putting my foot on the brake. The light that's on the push button comes on in 0.5 seconds every time.
In my last post (which i deleted because I didn't want to cause a storm), I mentioned it could be weak fob battery, or loose cable/wire/switch at the brake. It still could be a loose cable/wire/switch at the push button ignition switch that's not triggering consistently.
Have you timed how long it takes after you press your foot on the brake before the light comes on the push button? and is it consistent?

 

My wife and I were unaware of the light on the start button. I mentioned this to her and this problem has not recurred. I think that we'll change the remotes batteries anyway. Thanks for your help.

 

that's what we are here for....
