Guys i am really disappointed with my dealer or i should say Lexus Corporate as they are not helping me what so ever!!! I purchased my car back in Aug 08 with 5k miles on it...It was a demo car...Anyways right after i purchased the car i noticed strange metal clicking sound after the car warms up and i brought it to their attention. So the mechanic checked it out and he agreed that their is some strange metal sound, He told me that they will have to call the lexus regional rep and see what they have to say about it...After waiting for their answer they said it's normal and can not do anything about it!!

It's definitely not a normal sound as my friend has an IS-F too and his does not sound like that...I know that these engines have direct injection sound...This metal clicking sound is coming from the bottom of the motor and it gets loud..It's more noticeable on the driver's side bottom.

Guys if someone knows of a good dealer in NJ/MD/PA area let me know...i want this issue resolved as my Dealer is just BS'ing me!!!

This is from Lexus of Cherry Hill, NJ where me and my friend both purchased IS-F's on the Same Day.

Sorry for venting guys

 

Why don't you just go to another Lexus dealer?

 

Next time you hear it, if you pop your hood, can you hear it towards the top of the engine? I hear like a tapping sound on mine and the dealer said this is normal. You're right it does sound kind of like a metal clicking/tapping sound. You can hear it if you go near the wheel itself, however you can hear it better if you open the hood. I'll have to see if I can record a video sometime.

 

mine does the same... like little chimes

 

I had a Yamaha bike that ticked incessantly when I bought it. I had the valves adjusted 5 different times thinking it was a valve problem. It wasn't. I complained to no end. Yamaha sent me a letter telling me the engine was fine and they don't fix "engine noises" they fix broken engines. When I did a bunch of work to it and made it even more powerful, the ticking got louder. The engine never failed. It annoyed the crap out of me, but after I'd rebuilt a few of them I found out they really did ALL make that noise.

I'm sure your dealer doesn't want to spend a bunch of hours troubleshooting the noise only to discover there's nothing broken they can fix. They invest the dealer's time in troubleshooting (or you pay for this time) and if there is no warranty issue, the dealer either eats the troubleshooting time (no dealer wants to do this in this economy) or you get charged and you end up even more P.O.'d because they're charging you money and they've not solved the issue. They're actually erring on the side of caution.

So, if you really want it fixed, you need to break the engine. They'll fix a broken one for sure. They just won't invest a lot of time in troubleshooting noises because they know they're going to lose. It's business.

 

check this out, hope this can help you.

I am not 100% sure if this is the problem, but i wish it can help.

Guys....Thanks for all the replies....This metal clicking sound is not the usual new lexus engine like sound...Its only there after the engine has been warmed up....It is very loud metal clicking sound that appears from the bottom of the motor...I am aware of the regular ticking sound!!! i have driven other is-f's and i have still yet to hear something similar noise.

I guess i'll have to record the sound so everyone can hear it!!!

Maybe one of the CL member who has heard this sound can chime in

 

Today 12:09 AM
flipside909 Why don't you just go to another Lexus dealer?

i will be making an appointment with a different lexus dealer this week. I'll keep everyone posted how that goes

 

make a video and post it on youtube so everyone can hear

 

Hopefully Soon!!

 

i agree, the sound is not our usual direct injection noise, i dont hear it in my car. The place where we bought both of our cars from, looks like its degrading in service. i duno its not the "welcome feeling anymore" oh yea the dealer close to us, is even worse or was back in the day. I remember the older sales guy didnt even let us test drive the is350 when it came out. He asked us that and i quote" do you what the payments gona be for this car"
just because we were young they discriminate. that was the reason we dont like our local dealer.

 

"Normal", "Unable to duplicate" or "No problem found" is a standard response when they can't diagnose the issue. I would request a Lexus Field Engineer and let him explains to you why it's normal. Escalate to Dealer GM to get an appointment if require. Just make sure the noise is not intermittent. It can be heard and duplicated consistently.

Please post update and good luck.

 

Noise is there on consistent basis after the car has warmed up fully!!! If i turn the car off for 15-20 mins and then restart it, noise is not there...I have to go drive the car for 5-10 mins or let the car sit for 15 mins idling and you can hear it!

 

My guess is not on or inside the engine block.

You say it takes 5-10 minutes of driving with that engine, even after a short rest shut. To me it seems that's the time it would take for heat to creep into something that is on something like the drive belt, or maybe the cooling fans. Did those guys try the old trick of putting their ear to one end of a radiator hose while fishing the other end around like a stethoscope?

I'd say if it's something loud and bad enough that it's about to fail, it will probably happen sooner than later. Make sure to prepare your "I told you so" lecture if it does.
