Hey guys just got a 2007 IS350 loaded for my mother.


I hear a little ticking at idle from the engine, I think I remember hearing this on the old IS300s and a couple supras. Is this common and what causes it?

thanks

 

its normal, its the high pressure direct injecter sounds

 

Sometimes embarrassing going through the drive thru with the sound hehe, since its amplified 10 fold.

 

I don't notice it on my car. May be i have to pay more attention to this. How does it sound? Is it "tick" 3 seconds "tick"???

 

constant tick
I honestly don't know if its injectors, that sounds strange
sounds more like drivetrain noise

I think ive heard it on other lexus and Toyota vehicles though

 

Might be from the alternator. I am very curious about the sound you talk about, may be a video to show this. I never notice this in 2 years driving the IS lol.

 

It is the injectors. This is common with quite a few of the Toyota/Lexus models. My Tacoma made the same noise, and almost every Tacoma/4Runner owner would complain about it when I was in the dealership world.

 

Injectors or the mechanical fuel mechanism; either way, it is completely common.

 

Thought the same thing whn I got my is, it's common, our engines are quiet for the most part

 

Its a common "tick". I also was concerned for my 2006 IS350, so i went by the dealership last week and had a rep. start up a 2014 IS250 and you could hear it.

 

4TehNguyen is right on the money. This is normal for all Lexus's

 

Normal, since the end of 2005 for high-tech engines. Love the sound. Very Lexus and very modern. This is the engine note of the future and Lexus had it first, along with Audi.
