I bought a 07 GS350 back in September and I noticed after the engine warms that there is a rather loud ticking noise under the hood. I asked my dealer about it and was told this is normal (they stated it was the fuel injection).

A friend of mine in VA has the exact same model with no noise and the wife and I looked at one in Loveland CO and it did not have this noise.

Has anyone else experienced this problem? It is loud enough that going thru the toll boths in Denver you can hear it echoing.

The sound of the direct injectors, which is normal, in my GS is very faint. It's acceptable as far as I'm concerned.

very normal, don't worry about it.

x 3, normal. I really notice this when I pull into my garage and leave the motor on. I wouldn't expect someone who parks it outside to notice this unless they are very **** and know everything about their car... LIKE ME!

Hi ShoganCO,

The sound you are hearing is a characteristic of Direct Injection a feature that is relative to certain new Lexus engines. The loud sound you are hearing happens for the first 15-20 seconds during warm up. It quiets down after that.

We actually discussed this topic not too long ago here:

i was about to post up and ask the same question lucky i searched.


I went to look at an 06 GS300 and hear the noise i thought somethign might of been wrong with the car. The sales man said its normal so i asked him to start up another GS300 and heard the same noise but only quieter than the GS that i was looking at.

good to hear that its not an issue.

Am I wrong or did sm1 say that it's only makes the sound on the V6's?

If you haven't purchased a car yet, look for a GS350. Well worth the extra money. Check for another thread where people were asking if they regretted getting a GS300 over a GS350. Regardless, both are nice and will get a person from point A to B.

Din

yes i jsut read that thread. now might have to reconcider. might look for the 350 now.

Anyone else find this noise still going on? Did anything help it? e.g. better oil, etc.

Considering the noise is produced by something that has nothing to do with any parts that should ever touch oil, no. This is just the way the cars are.

It could be the direct injectors making that noise but it shouldn't be that loud. There is also a recall on the valve springs that the dealer will do for free. Check with your Lexus dealer locally to have them replaced.
