Exclamation Weird Starting Problem

I'm having the same problem with my 2010 RX 450h. Has been in the shop for last few days (Feb. 2018) and they haven't gotten it to fail until today, so they said that they adjusted to brake sensor! Going to pick it up, we'll see if it continues to fail or not. They also said they were not charging me, so that makes me wonder if they know something they're not owning up to. Is there a website that shows reported issues but ones that don't have a recall?08-28-11, 11:53 AM #1

Wierd Starting ProblemThursday I did a major clean wax and polish job on my 2008 F and when I came back Saturday and tried to start it there was just the CLICK CLICK CLICK and it wouldn't start. So I thought maybe I left something on when I waxed it so I recharged the battery.

Came back a some hours later and tried to start it. First of all I noticed the green light in the engine start/stop switch that you push to start it only was amber. The dashboard lit up with all the indicators and the tach did its thing like when it is ready to start but the engine wouldn't even try to crank. Still no green light. My foot was hard on the brake when trying to start. Car is in Park. The headlights were bright indicating to me a good battery charge.

I came back an hour later and still no green light and still no crank. Foot was hard on the brake pedal. Car in Park. Still no green light on the start/stop switch and headlights still bright. I went and got my wife's key and it started right up!!. I turned the car off and went and got my key and it started right up again. By the way I had replaced the battery in both keys just a couple months ago.

Whats going on? I think maybe a computer in the car or in the

Whats going on? Is there a way to reboot the cars computer. Maybe the engine immobilizer is out of sync with the car. How can I reliably start the car if this happens again?

We are talking about the 450H? Do you get READY in the display?

Try holding YOUR key fob right next to the start button when you press it--use the same hand. If it starts, then your "new" fob battery has already failed.

But the 450H need not start. It should show ready and ICE starts when the computer thinks it needs to. That is why I asked for clarification.
