After having the new TL-S for only one day, it spent the next week at the dealer waiting for (2) new rear struts. The noise over even the slightest bump was very prominent. Got the car back two days ago and now I can hear other clunking or thumping noises from the rear. Last night I got the bright idea of checking the tire pressure, and found it to be in excess of 42psi. I dropped it to the recommended levels of 33 front and 32 rear. We'll see if this helps to soften things and hopefully do away with a lot of the obnoxious noises.
What's funny is the low tire pressure warning light is now on and reports that there is only 29psi in the tires. So now I suppose I'll just keep bumping it up to find out what it takes to get the light to go out.

 

Same problem for me. Bought it a week back. Black with thope interior. Was happy for a week.

1. Took delivery on 5th
2. Noticed flapping sound in the rear of the car on 8th
3. Took to dealer on 10th. Service is closed.
4. Went back to dealer on 12th. Service says it is a design flaw. Struts are making noise. They call and tell me that they requested HQ to send replacement struts which can temporarily solve the problem. Service informed me that once Acura re-designs the struts, they will call back and replace them again.
5. Still waiting for the car as of today.... 13th...
