At low speeds brake calipers shift, causing a clunking at one to four wheels. Problem is most pronounced when a shift in momentum occurs; backing up and then moving forward; stopping on a slope; stopping and then moving foward again.
The result is an ongoing "thunk", "clunk", or even a "clicking" during low speed driving.
I'm trying to gague how wide spread this issue really is. Please vote in the poll.
Thanks. |

If the majority say "yes" and its not a safety issue, then I take it that, its a characteristic of the MDX, and ignore it.

| If they could transfer the clunk from the brake to the turn indicator, I'd be able to tell when it's on! :D |

Then you would be complaining about the noisy turn signal!
Maybe then they would fix it ! |

This looks like a pretty common feature? of the MDX and maybe Acura vehicles.
I feel left out. My MDX is not a clicker. For those of you that hear it did it occur when you first got your X or did you have to put on a few thousand miles before it started to click?
Do you need to turn off the stereo and roll down a window to hear it? |

I mentioned it to my dealer, and they put "Standard MDX brake shifting noise" on the workorder and gave it back to me.
I don't think it happened right away, it took a little while for it to start.

I noticed after a few thousand miles & only when I roll down the window & turn down the stereo. I haven't bothered to have it fixed & won't unless I see that it's a safety issue. |

| Never heard a thing (01 MDX w/68K). Then again I've never listend for it. What with my music blasting away at blood-pouring-out-ear levels, how could I hear anything! Gotta go I think my wife's calling me (or is that just the voices in my head). Tomorrow I'll drive without music and let you know. |

| With mine it is also windows down stereo low. I think I am hearing it more now. The noise is a click at slow speed. I notice it when I am first starting out. |

I thought most report the noise after the X has some real miles on it...is that true? |

| srpbep |
| We've got it (thunk). Has gotten progessively worse over time. Dealer worked on it once with no improvement. They claim that they can now fix it. The X will go in at the end of the year for this problem, noise from the 2nd seat, and routine maintenance. |

I never noticed the clunk when the MDX was new ... but with 50K on the vehicle it's quite noticeable. It doesn't bother me and it sounds like it's a characteristic of the vehicle.
If it's any consolation, my parent's RX300 also clunks (but didn't clunk when it was new). They have 30K on their vehicle. |

Some people's posts indicate they're not sure how to tell the difference between the gas tank thunk and the brake clank.
** The gas tank thunk sounds like a softball rolling around in the trunk.
** The brake clank is unmistakeably mechanical. |
|

| I noticed something when we had less than 1000 mi. on our X. Besides hearing the sound (just a little), I can even feel it when I'm braking, at low speeds. Is this a part of the "clunk" too? I feel a gentle thump while pressing the brake, most often first thing in the morning. Is anyone else experiencing this, too? |
|

| TallahasseeMDX |
| I have the brake clunk. Have had it since I got the X, although it's gotten worse since about 18k miles. I'm almost due for the next service appt and I'll mention it then. Not sure whether there is a fix or not. Have had nothing but good service from my dealer, so if it can be fixed and I ask them to do so, I expect it will be. |

| Desant |
| It seems like an issue most MDXs have, including mine. It appears also that this issue does not cause problems. |
|
|
| srpbep |
Desant,
Minor disagreement, I find it DOES cause a problem:
** I agree, it does not have other adverse mechanical problems that I am aware of.
** It bothers me some = :3:
** It bothers my wife, her vehicle, a heck of a lot = :3: :3: :3: :3:
Soooo, for me it actually is a BIG PROBLEM. I don't enjoy parting with $40,000 to have a wife complaining about the vehicle. She has NEVER had a car that did the clunk and doesn't want one now. This is a VERY BIG PROBLEM. |
|
|
| catzx6 |
TOTALLY AGREE, srpbep!
I feel the exact same way your wife does, I'm the main driver & my hubby seems unable to notice anything in the least negative about our X. But I do, these little things are annoying at best, but I don't understand why this upper end vehicle has all these little "characteristics," as termed by the dealers, service, & Acura? I don't think they should be ignored. It makes me think there could be underlying problems causing these sounds, noises, etc. |

I TOTALLY agree with srpbep and catzx6!!!! These are NOT norms for MOST (except acura) new vehicles!! If honda/acura reads this board hopefully they see all the so called NORMS!!!

| My 2002 makes this clunking noise everytime I go from reverse to forward or vise versa...It started making this noise at about 3000 miles (at least that is when I started noticing it). I do not have to have my windows down, and can usually hear it with the radio at a normal listening volume. I never really thought of it as anything other than my brake pads shifting. |
|
|
| TonySJ |
I have an 2002MDX-base model with ~9.5k miles on it, and started to notice the clunking noise every time after start-and-drive (from cold engine). I never heard the noise again after that. I may try to roll down the windows and really listen to it to be sure.
I will mention this to the dealer when next service comes around. I'll report if they do anything to fix it. |

| rudy331 |
| Not sure if what I am experiencing is the standard "clunk/click", but have noticed on my 03 (4,000 miles) that several times when slowing down and hit a bump at the same time (speed bump or otherwise) that it feels like something is loose and hitting the brake from underneath. Reminds me of maybe somebody hitting it underneath with a wrench. Going in Sat. for oil change, and to have cargo cover looked at should I also bring this up or is this somewhat normal???:( |

I just wanted to chime in that my son's 2001 Honda Civic EX does this, too. It's usually after he backs up, shifts into drive, and then applies the brake that it clicks.
When we told the Honda dealer about this weird click, he said it was normal of all Honda's (Acura's too) and it was because of the brake calipers shifting when going from reverse to drive.
So while I know it isn't the greatest noise, there is a reason for it, and it happens in all Honda's and Acura's, not just the MDX. |

The idea that brake clunk is "normal" when an auto/truck goes from forward to reverse and vice versa is a load of baloney. How many of us have had vehicles which did this before? I'm going to speculate that very, very few recall such a noise.
IT IS NOT NORMAL, NOR DOES IT CREATE CONFIDENCE. Instead it suggests that something is wrong with the MDX and that there is a danger that whatever it is will cause harm to the MDX and to its occupants. Acura needs to determine what is going on and provide a fix to all MDX's which have the problem! |

| craig02mdx |
| For whatever its worth.....Every Honda or Acura I have owned has done this (94 Integra, 95 Accord, 2000 TL, 2002 MDX). By now I just assume its Honda/Acura. |

I finally heard the gas tank slushing around when I had a half a tank but only when I was backing into our garage. Otherwise the music is blasting.
As for the brake, sometimes I think I hear something and when I try to recreate the noise nothing happens. 1500+ miles and everything is ok so far. |

| I have an '02 MDX which used to click when coming from reverse to drive when you first hit the brakes. There are shims that need to be installed. I had them installed two weeks ago and no mor clicking. There is a post on this site with the part numbers for the shims. I took them in to my dealership and they did it under warranty of course. |

I printed this out and took it to my service guys at Acura.

I recently went for my second oil change (12000km) or 7500mi. and it included brake service??, suddenly no more brake clicking.
haven't heard it since:5:
It never really bothered me :rolleyes: anyone else notice this too. |

Shim kit installed today under warranty. So far no clunking when parallel parking, but I've only had two chances to park it.
Hope the "no-clunk" change is permanent. Front end seems a bit tighter too! An added benefit, if it is a real added benefit.

Yes, I have the brake click. My x caught it last summer and still has not recovered. It bothered me at first, but now I really don't notice. When I asked the dealer, they said it was a characteristic.
They service tech mentioned that there had been a similar problem with another Acura and they eventual came out with a retrofit. (maybe a 99 TL?)
He did not mention the shims, I will ask them.

Colemanpc,
Great description.
My new X (picked up in Dec 2002) had that distinct feature from the start. I did not notice it right away b/c I was enjoying the sound system. However, I did detect it well below 1000 miles. I will have to keep everyone updated after I bring it in for servicing and warranty work.

| Mine is still very inconsistent, when I do hear it, it is usually when approaching a stop sign or red light and I hear a "thunk" sound from what appears to be coming from the middle of the car under the center console just before the X comes to a complete stop. Definitely not the gas tank sloshing sound, I can reproduce that one on demand. |

| Alright...I was a little upset yesterday. I pulled into a B.K. for a croissanwich(mmmmmm) and when I pulled up to the takeout window with the window open I could not believe the noises coming from underneath my bus. I was hearing brake clunks and clicks. Also I noticed that shifting from park to drive is very loud. I can't remember it being that loud on other vehicles. It is not the transmission but the linkage between the shifter and the unit I believe. Is everyone experiencing this sort of loud noise during shifting? I realize it was probably accentuated by the fact that I was near a wall and the noise would be louder than normal but.... |
|
|
| hammermdx |
| I haven't noticed that one yet hockeyplayer. I'll take a listen the next time I pull up to the ATM. |
|
|
| srpbep |
| Our dealer just installed shims and the brake noise is gone. Don't know how long it will last but sure won't miss it while it's gone. |

Most MDX brakes clunk or click during the 1st application when going forward or reverse due to brake pad shift and clearance issues. Acura has an update rear brake pad shim kit that will take care of this noise which applies to all 01-03 and some 04 MDX's, however there are no updates for the fronts as of yet.
Refer to TSB 04-009 Clunk from rear brakes
As for the clunking / clacking noise every time you shift from reverse to forward or vise versa..........all X's make this noise some louder then other's. This is a normal characteristic of this breed. :) |

I had pretty bad clunking.
Recently, I had my front 2 struts replaced under warranty since they were leaking.
No problems since...but it's only been like 2 months so time will tell.
The ride is MUCH better...seems like there is a "break-in" period (???) don't know... |

Started on my '04 touring at about 6K miles. Hopefully it won't get any louder than already is.
The clunk is 'normal', and not a safety issue (as previously said), but sure as hell a bad design. First car ever to do this noise. The reason is pads are held in calipers without any pins, and the tolerance between calipers and pads causes the clunk when changing directions.
What I do is as soon as I put 'D', I touch the brakes so instead of a loud 'clank' when braking at speed for the first time after backing up, it's only a small 'click' at a few MPH.
I read the TSB, and it's not a fix; just a band-aid, so I won't even bother. Many people reported the noise back as soon as the same day after the fix, corroborating my suspicions.
Good evening people. |

THIS is GONNA SOUND WEIRD...But after I had all four brake pads replaced and the rotors resurfaced at my DEALER...the CLICK WENT AWAY!!!
Is it perhaps the original pads that Acura installed at production is below than average quality?? I dont know..All I know is...my brakes DONT click anymore...NICE!!! I LOVE IT! |
|
|
| ELP_JC |
Mine didn't either when new; wait for around 6K miles :D
The brake calipers are probably slightly tapered, and when pads wear, the gap increases causing the clunk. The clunk always show up after a few thousand miles. |
