Good luck.
I have an 09 MDX with a rear suspension problem that is driving me nuts. Four times in the shop in six months and still the racket from the rear is ever-present. Acura knows it's a problem but does not know the cause. They say it is "commercially acceptable" and they won't try to repair the problem. Another Acura in my future? Fat chance!
Has anybody actually had their rear dampers and bushings replaced per the bulletin? Curious to know if it actually helped.
I'm wondering if it has to do with the back being lighter than the front. Or there could be less sound deadening back there. Or it also might be the acoustics of having all that open space back there.

Acura knows it is a problem but they don't know how to fix it. The are not sure what it is, though it sure sounds like bushing problems.
My dealer, McGrath Acura in Illinois, has tried very hard to fix it.
Finally, as of today, they are going to take a new suspension from a more recently built MDX and place that in my car - no charge. They believe that Acura has made some modifications to the new suspension and that might solve the problem. Or maybe they are tired of my whining and just "throwing parts" at it to get me out of their hair. Either way, the customer and service managers have been good to work with. My suggestion: get those two involved at your dealer. I hope you are still under warranty. Good luck.
Sure, all of the tires/shocks make thumping noises when going over bumps - this is normal. But there is no doubt that the right rear is twice as loud as the rest and has an odd, boomy quality to the sound. It's annoying, but I'm not sure there is much we can do. If a brand new car with the latest suspension has the problem, there is an obvious design defect at fault. I wonder if the 2010's will have the issue?
I wish you well with your MDX. Other than the thumping it has been a great car.
Update: Wife took the car to dealer today and had them look at it...dealer plugged in and did diagnostic check of it. He said it was something related to the multiple key memory system. Where if i used my key to unlock the doors...it would set to my seat and radio station settings. However, i noticed that we lost both of our settings a while back...but did not pay too much attention to it. This seems kinda bogus because it doesn't have anything to do with the previous warnings of ABS, VSA and SH-AWD. I want to resolve this before my warranty expires next year.
Any opinion about this would be helpful.
thanks
My vehicle has 7500 kms on it, just got it in July. OVer the course of the 7500, when i go over speed bumps, not all but some, i hear this horrendous screech scraping noise from under the front of my car. Everytime, i stopped the car and got out thinking something was dragging. The last time this happened, 3 weeks ago, when i was going over the bump and heard this, my car felt like it was going to seize, but then kept going.
The first service i took it into was two days after that. He said it was my ABS kicking in?!?! Is he kidding? He wouldn't even take my car in - he said i'd be wasting my time, they won't find anything. I've been driving for over 25 years and i've NEVER heard any of my abs systems making that noise. Besides, of the five times i heard it, it only tried to seize once.
I took it in to another Acura dealership and the service dept drove it, and hoisted it up. They couldnt' find anything. They kept me on record and said if Acura notifies them of anything, they'll call.
Has anyone heard of or experienced this? Does anyone know what this is?
Please help me.
Thank you
A car stereo shop is probably cheaper than the dealer, but call around.
Or you may want to remove the bezel yourself and see if you can pull the player out. There's some links in the How to Remove a Stuck CD guide for d-i-y access to radios and players that may help.
Or maybe an owner here has done it?
Try first doing proper transmission fluid change. This means use honda only fluid and they have to change it 3 times in a row. Cant drain 100% out on a single change so you need multi changes.
DO NOT TAKE YOUR CAR TO AAMCO TRANSMISSION SHOPS, TAKE MY WORD FOR THIS.
I had a brand new MDX loaner while they were working on it. Same exact issue. I'm guessing only people who drive on bad roads notice and/or complain about this issue.
I'm now convinced that there was nothing "wrong" with my MDX, which is why replacing parts didn't fix it and why the loaner has the same issue. Unfortunately, it seems to be an inherent flaw in the design. Unless Acura engineers re-work the suspension, our dealers can replace parts until the cows come home with little or no effect on the hollow boom sound.
My dealer did replace my rear suspension with a brand new 09 suspension. The first 72 hours was like butter! Then the problem reappeared, but not as bad as it used to be. I am sure that as the miles increase on it, the problem will return in full throat! For now I have forgotten that the problem is present as it is so minimal.
My service guy admitted that it seems to be a design flaw. All the models he has driven also have this issue. Bummer. Not much else to be done - unless I want to call a lawyer. Nah, I don't want that hassle. It is disappointing, as I bought this car over Lexus and Mercedes and Buick because of the quality and reliability of the MDX. Not sure if I will be a repeat customer. Best of luck to you. Happy New Year.
I have had the car with a heavy load and the problem stays the same.
I should be clear that I have the sport model suspension. The standard suspension models had a recall on their suspensions for thumping. The sport model does not have this recall.
As far as the type of streets that cause the noise, it is not necessary hard core potholed types. It can be a manhole cover or even pavement changes that make the thumps. Even backing out of my driveway from the apron to the street caused it. Focus on very moderate bumps at moderate speeds (under 40 mph) to hear the thump. For now, my new suspension is staying quite quiet. Good luck to all.
My experience has been the same as yours in that it seems to handle big bumps, dips and large potholes just fine. Rather it's the small stuff (cracks, manhole covers, etc) that make the noise anywhere from 10-40mph. I was in the city today and it was driving me nuts!! And for some reason, I hear the noise from the rear-right, even when the bump hits the left side of the car.
There is a small mahole cover on my street, covered with some rippled pavement. I hit it every day, going about 20 mph. The front passes over silently, then BOOM!
I don't expect a silent ride. I expect bumps to make noise. But this particular noise has a certain boomy quality to it that is very irritating. I really hope I can find a fix to this someday soon because it's ruining an otherwise GREAT car.
Did anybody experience this? Could this be in the setting of the automatic door lock? I bought the vehicle new about a month ago. Wanting to get some opinions before taking it to the dealer.
Also the driver side window was making a screeching noise when rolling up. It did not make any noise rolling down. I didn't see a mark on the glass. Any guess on what could've caused this?
Mine is still better after the rear suspension replacement.
The "recall" I mentioned applies to the service that you had done on the rear suspension. Perhaps I used recall incorrectly. Rather, it was a service bulletin of sorts.
Sorry that you are not getting any satisfaction. Indeed, it does ruin an otherwise GREAT car. Best of luck.
i always thought the ppl with tech and ent. got jipped because you lose the aux audio connection in center console that the tech has just because you added ent. package and got the outlet in the console.
you shouldn't lose anything from the tech package just cus you added the ent. package.
that was terrible of them.
i hate having to plug in a separate charger for the iphone and fumble with it to change song plus have to connect it with a y cable (red and white audio to headphone jack in the iphone) from the rear inputs behind center console.
i hope there is a way to add the usb connection of the 2010 into the console of the 09 to make up for the fact that adding the ent package took away the aux audio input of the tech package.
A couple of days ago the radio stopped working for FM and AM channels, however XM, the CD player and the DVD work fine.
Any ideas on what may be the issue here ? Has anybody else here faced this issue and got it resolved ? I took it to the dealer and the service rep said they'll charge $125 to diagnose the issue and if its a dead radio it'll cost 600-700 to get it fixed. My car is out of warranty and I'm not in a position to fork out that much now I'm wondering if there is something simple that I can try - I'm quite hands on and am willing to try out any suggestions.
Could it be a problem with the antenna - and how is the antenna connected ?
thanks
I bought a new 2009 MDX recently and I am also experiencing the same high pitched whistling noise coming from the dash board. I drove only 1500 miles so far. I took the car to the dealer immediately and they inspected (took 6 hrs) and said that it is due to passenger window that was rolled down slightly, which I don't believe it. Has this problem been fixed for your MDX? If so, can you please let me know what the root-cause of the problem was and how it has been taken care of? I appreciate it.
Thank you!
I'll let others respond who also have the 09MDX. However, I have a 05MDX Touring and the symptoms were that this noise appeared to be coming from the engine/transmission. See my post 1767.
A quick symptom check would be to see the speed at which this happens (in my case it was around 40mph and above). When you notice the noise, take your foot off the accelerator and see if the noise goes away. In my case, the tech immediately diagnosed this to be a faulty transmission and replaced it. Since that time, I have not had that noise.
I found out that I have the same issue on my new 09 MDX. The whistling noise only happened after start the car and at the speed 20 mile point. I took the car to the dealer and they said this is a normal. They also asked Acura Tech Center and said every 09 MDX has the same noise. Does anyone has same problem on 09 MDX and got it fixed?
I have an 09 MDX [tech+ent] and noticed the same thing. On one certain road [speed limit 35, I'm going 40], my wife and I would always notice it. At first I thought it was some 'interference' from some cell towers, etc. But, the more I read, the more I think I've got the same issue as others. Normal? It shouldn't be but it seems a good way for the dealers/Acura to avoid the issue.
No - I haven't done anything about it for now except turn the music up.
I was able to reproduce the problem by rolling the right front window slightly down and it stopped when I closed it completely, which is very strange - High pitched whistling noise as apposed to wind noise. I believe it as I see it. I had to keep my MDX for two days at the dealer for thorough investigation though.
