Lexus Rx 450 - 59 Plate

[robpace]

I got into the car this evening, and twice pressed the Power Button , but the Ready light didn't come on ,all the other Dash Lights came on as normal. The car wouldn't do anything , so got out , locked it then unlocked and tried again , but still the same . Tried once more inside the car but still no Ready Light.

Got out and locked it again , and left it about thirty seconds before trying again. Luckily this time everything worked alowing me to drive home .

Anyone ideas ?

Thanks Rob

Was you foot on the brake pedal? If not it will only turn on the ignition.

[robpace]

Yes , it was Colin ( Did think of that at the time !)

I'd get your 12v Battery checked out, it probably isn't holding a full charge.

Hope you find out what the problem was please

keep us informed if you would thanks

I had this problem on a Jag, it was caused by a problem with the immobiliser chip in the key. I found the cause by starting the car with my wife's key, and then started the car with my key but inserting it upside-down.

Would be worth a try with another key if the problem occurs again.

Would it be worth changing the Battery in the key?

[ColinBarber]

If you have keyless entry then yes that is probably worth doing anyway but not sure that is the issue.

Everything has worked as it should do today for the Missus . Hopefully if it plays up again , it will be before the one year warranty runs out early next yet . Going to ring Lexus tomorrow to tell them what happened so they can put it on record.

Year !!

Who is the main user of the car? Maybe swapping keys for a bit will make the problem follow the key?

As colin says get your 12v Battery checked, I have just had similar on my 2yr old is, and it was a dead Battery, the 12v Battery on the is, is very small, once it weakens it struggles to start the hybrid system.
