#217 of 996 Purchased 2005 Acura MDX with problems
Mar 16, 2010 (7:47 am)
We purchased a used Acura MDX a couple of weeks ago and now it is making a unique noise that the dealership cannot figure out. It makes the noise when going forward at about 35 miles an hour and it is a short rubbing/vibrating noise that is quick to start and quick to end. Often only a second or less but happens quite often. They cannot seem to diagnose it since it is short lived and not a continual noise. I am worried that it is something serious and we want it taken care of while it is still under the 30 day warranty. Does anyone have any ideas? When others had trouble with the transmission what were the symptoms?

Does the tachometer move during the sound...in other words, if you are holding steady MPH on a flat road at 35mph, do the RPMs vary?

I would print out all of this Torque Converter and Tranmsission stuff and go to the dealer with it (armed with info). Get it well documented. They tend to stall on the diagnsosis as not to have to fix it within the warranty. I am dreading that I have a 2008 Honda Oddesy van (in addition to my 01 MDX) as I know what is likely coming. I think I am officially over Honda.

Return the car and get as far away from it as you can. The Deal knows what
the problem is, don't let him get away with this. Honda is covering up. Return the Car and buy something other than Honda

In my experience, I have found this sound is very difficult to duplicate. I don’t know what causes the sound, but I have spent quite a bit of time understanding the behavior of my vehicle. Here are my findings/suggestions/ideas:
1) Find a long side street with max speed of 30~35 mph and a very slight uphill slope. Drive in D5.
a) The street must be long enough to allow for the vehicle to shift through gears 1-5 as you slowly accelerate from 0 to 35mph. If/when you begin hearing the sound, hold your speed steady to sustain. A longer street will give you more time to dial it in.
b) The uphill slope of the street must consistent and minimal. If the slope is too steep, the transmission will shift back down to 4th gear and you will not be able to duplicate the sound. If the slope is not steep enough, the vehicle will not experience enough loading to recreate the issue.
c) The street must be free from traffic. If you have to stop, slow down or adjust your speed, it may interfere with your ability to tune in to the conditions described above.
2) Find a street described above near your dealer and practice recreating the sound before scheduling an appointment. Then take the service tech for a drive and replicate the sound for him/her at the same location.
a) This may seem time consuming at first, however, if you let the service tech drive on any street at any speed, he may never be able to replicate the sound.
b) If you are successful replicating the sound before your appointment, then you can schedule an appointment with more confidence that you will achieve a diagnosis.
3) Eliminate as much ambient noise as possible to help isolate the problem sound.
a) Turn off radio, climate control / fan, shut windows (reduce wind noise), avoid traffic, etc...
Please read through all the posts in this thread of the forum. Also, it wouldn’t hurt to search the internet for similar year Honda Pilots and Honda Odysseys to get a feel for general customer satisfaction related to other similar Honda/Acura V6 vehicles. If you have the option to keep or return your vehicle, this information can help you make an informed decision.

I will check this afternoon. What does this mean? It always happens on a flat road, never going up hill or down hill. If you feather the gas between 30 and 40 mph. it happens a lot.

I have the same problem and my local dealer does not seem to know what's going on either. I hope someone have an answer soon as to what caused this noise. I don't want something to happen while driving.

I am able to recreate the sound almost everytime. I have also recreated the sound with an Acura tech in the car. He was not able to figure out the issue. I suspect this is a transmission problem due to the symtom, but I am no expert. I hope someone can figure this out so I can get this issue fix pronto, it is beginning to make me nervous driving on the freeway.
