I have an 02 TL-S, 800 miles on it...and it's idles loud...not just a constant hum like I like...but a chunk chunk chunk...one that I didn't notice before and I didn't think would be coming from such a nice car. Guys, is this normal? Or should I take it in?

Where is the noise coming from? Do you hear it while in the driver's seat or with hood up?

A/C on or off? I've noticed this too, but I thought it was just the fan....

I heard it while I was on my way in to Mailboxes Etc, I was outside the car. I was in too much of a hurry to pop the hood but I'll do that tomorrow and tell you guys where the sound is coming from. It sure didn't sound like the AC but well...I hope it is. If it is I've never heard AC do that...sounds awful.

While I'm at it...when I first get in the car and put it in reverse, I start driving backwards out of my parking space and it feels like something is pushing down on the wheels for a minute. Now I've had ABS on the other car I owned, and it did do self tests...and I even posted to another guy that was probably what it was...but it sure is pronounced, and not only that but it only does it after I've been moving in reverse for abotu 2 seconds....not just sitting there. That is what it is right?

That does not sound normal for the A/C on a car this new. The A/C compressor should hum while engaged and click once during engagement. The electric fans are usually the loudest of all, especially the fan for the A/C condensor. Again, only a hum, but louder and only from outside the car. A continuous rattle sounds like a bearing.

Just thinking out loud. Need more info....

If you are close to the dealer you should probably pay their service dept an impromptu visit just to be safe.

That noise when you reverse yes that's the ABS self test...I say take it to the dealer for the other noise.

It's not the AC...I turned the AC off and the same noise was there...albeit a little quieter...but still VERY noticeable. I am going to have to take my car in anyway to get them to look at a deep gouge in my front hood...two actually one next to the other, all the way down to the metal. I just noticed it today...they're both about 1/8" long. Looks like a vampire bat took a bite out of my hood. Anyway so I'm taking the car in for that so I'll get them to look at it....ARGH!

Austin519,

I had this exact same problem when my car hit 1,200 miles. I took my car to the dealer and they immediately pin point this to the idler pulley. They replaced the pulley and the sound disappeared completely. When you take your car in, you might want to mentioned the idler pulley to them....good luck!

wonder if a common thing cuz I brought my car in couple months ago for the same reason (idler pulley) at around 2k miles.

About two weeks before I read this thread, I noticed that when my TL-S (8K miles) was up to operating temperature and it was idling, whenever the compressor would kick on I would get a rattling from the pulley area (like the sound of an agitator in a spray paint can when you shake it). When the compressor kicked off it would go away. I guessed it to be the idler pulley as well. I just went in for warranty service at Acura of Avon for the seatbelt recall and the sunroof squeak, but unfortunately all I got for the pulley was "could not duplicate." To be fair to the dealer, I was with them trying to demonstrate the noise and it wouldn't do it for me either. It's like trying to show off a trick you taught your dog--they'll do it 100 times correct until someone is watching.

Anyway, I plan to keep an eye (ear) on the situation and bring it back if it gets worse/returns.
