IS300IS

Hi.
I just purcahse 03 IS E-shift 3 weeks ago, and I just notice that I have a ticking noise under the car while I park my car in my garage when the engine still running (I can hear the noise pretty well when the door is open, but none when the door is close). I usually hear them when the car is warm/after use. It only happend on park gear and gone as soon as I shift it to reverse or drive gear.
Are this normal for IS?
Thanks

You sure it only happens during the times you stated? Sounds like the ticking is coming more from your exhaust and catalytic converter cooling off from the heat.

Yeah, often the heat shield will expand and contract and make a little noise

Sounds like normal heat expansion/contraction from the exhaust system.

Thanks for the respons guys.
But I still do not understand, because the noise is gone as soon as I shift my gear from parking gear to reverse or drive gear. is shifting make a different on heating shield?

Yeah, if you're unsure, it wouldn't hurt to take it to the dealer for them to check it out. Better safe than sorry...especially since we're still under warranty.

are you sure it's not just the noise of the injectors. I had asked the dealer the same question from a sound I heard from around/under the car and he had said it was just the ticking of the injectors. Is it a constant ticking noise?

hey man i have the same problem with my 01 IS. for some reason when it is in park with the motor running it has a ticking noise. it sounds like its coming from the rear of my car near the exhaust....... Is that where yours is coming from????????

The noise is comming from the rear of the engine area,.

martialart

is it a consitant ticking? or inverted ticking?

It's not happend all the time and It's not constant.
It might be the muffler join or heat shield?
actually how many heat shield we got in the car?
