Hello, I hope someone here can tell me what is wrong with my 2009 RX350. I cannot ignite the car, and it even did not have ignition sound when I started. Is it merely a battery problem, or something else more serious?
Any comments would be appreciated.

 

Battery should be the first place you look. Has the clock been resetting or any other electronic strangeness?

 

Why don't you start with the battery, to eliminate it as the source of you problem. Are out of the warranty?

 

Since you have a 2009 it would still be under warranty. You should call Lexus Roadside Assistance and they will dispatch a Lexus Roadside Tech or tow truck. Their response time is usually within an hour.

 

Make full use of the warranty.

It would help us to help you, if you state your problem a bit easier to understand.

Fails to ignite -> are you saying the starter turns the engine and by the sound of it, the engine is being spun are reasonable rate and the engine fails to catch?

If so try holding down the throttle near half way. If it works then there is idle control problem

There may be engine immobilizer acting up. Try another key or make sure there are not other keys in the key ring.

call roadside assistance....your car is still under warranty!

 

Just happened to me. Dash lights are all on but it doesnt crank. Called roadside which called AAA and they did some tests. I need a new battery.

 

Call Lexus Concierge. They will take care of your RX.

 

I took it on to Longo lexus and they replaced it for free. I have an 08 with 41k.
