Hello everyone just looking for some help identifying a noise Issue im having so i can get it fixed....i have a 2009 Acura TL Sh-awd there is a noise coming from under the car sounds more like a rattle everytime i hit a bump at any speed i can hear it...front wheels hit a bump i hear the rattle then when back wheels hit the bump it rattles again. Ive been told there is a common noise issue with this car but i dont know what it can be. Any help would be apprecited. I took a video of the noise but im trying to figure out how to post it.

 

youtube.


go down there and look at what's broken

 

I have looked under the car on a lift and nothing looks visibly broken...ITS MORE OF A RATTLING NOISE

 

could be brake shield, exhaust heat shield, etc.

 

Could be TSB 12-041: Front Suspension Clunk in Hot Weather

I'm guessing struts/shocks.

 

we can guess and suspect and conjure up different scenarios, butt without physically inspecting the vehicle ourselves.....your guess is as good as ours

 

Brake pads loose, rattling when you hit a bump? Try to hit a bump with the brake pedal pressed a bit and see if the rattle is still there. Just a thought...

 

Did you get the warranty service done for the judder? For me they took off a heat shield I guess to either access the transmission or to change the trans oil. But right after I noticed that when I hit a bump or something there was a "clunk" type noise. Made a U turn and told them what's up and within 20 minutes they were like oops, we didn't tighten the heatshield properly.

 

I have a similar issue, but mine only seems to occur at the right rear wheel area... Had 3 very experienced mechanics look/test drive it. They heard the noise, but couldn't figure out what was wrong. They said if it bothered me enough, bring it to the dealership as they might have more info/experience with that particular issue, but at my car's age/mileage (2010 w/ 127k miles) all of them said it might not be worth it since my suspension components look to be in good condition. Might bring it up at the dealership and see if they can figure it out next time I'm there for service.... Would be worth a few benjamins if they can fix it, but not worth much more than that to me personally.

 

can you describe the noise?

could be literally ANYTHING tho.....
axle, wheel bearing, etc

 

video?

 

funny!
a friend sent me a video of his 3G making noise...
I was like...uhhh that's normal... mine sounds like that.....
he came over to my house and i drove his TL....sounded NORMAL! LOL!
he did point out the clicking to me, but it was hard to hear....
