Every time you accelerate beyond a "gentle" level in the MDX, from a stop or a low speed, on a tractive surface, you are putting an unusual, mostly undue, level of stress on the driveline components.
So driving style, or even geographic region, might have an adverse impact on how soon one of those components fails. Note that the MDX was switched from the VTM-4 system to the SH-AWD system at some point which seems to have helped alleviate the failures.

I bought a 2005 CPO 3 years ago in Canada with 50K miles. The transmission failed 3 months after I bought it and was replaced under CPO warranty. Since then, little things have slowly started to fail with the age of the vehicle. For example, lights that illuminate switches will fail, the homelink buttons and the reading lights next to the rear view mirror, automatic door locks on the passenger side etc. Nothing big, but small things. I have meticulously maintained the vehicle with all services performed including tranny oil, VTM fluid, rear transfer case fluid, coolant etc. A few months ago, I had a major failure of the radiator which (according to many posts on the Internet) could potentially harm your transmission because of the way the radiator is designed and a radiator leak may cause tranny oil and coolant to mix and end up in the tranny (not good). I must have driven about 10 miles before the tranny went into fail-safe and shut down (that's what the dealer told me). He fixed up everything, did several flushes etc and told me everything is fine. The vehicle drives fine but I went to another Acura dealer for a complete inspection of the work and the other dealer also confirmed that there is no damage to the tranny and the work done by the first dealer was top-notch. I wanted to get that peace of mind as my timing belt, water pump and serpentine belt is being replaced this month at 100,000K miles and that is a big expense. I intend to keep the vehicle for as long as I can so I am going to eat the $1200 expense but you just need to be mindful that on an older car you may have unanticipated expenses. But it is a great vehicle and is built really well.
#886 of 996 2005 MDX Transmission Question
Aug 23, 2012 (6:39 am)
I am thinking of buying a low mileage (30k) 2005 MDX and am concerned over the reports of transmission/TC issues. Can anyone offer some recent information/experiences with their 2005? We have friends with a 2002/124k miles and have had no issues. Did Acura issue a service order/recall on them? Thanks for the help.

We purchased our 05 Acura 6 months ago from a dealership with 87k on it. A few weeks ago we noticed it shifting hard, check engine light coming on, the drive light on the dash would flash when it was in gear, which in the manual indicates transmission issues. My husband checked all fluids again and all was as it should be. Today I can't shift it into drive at all and barely got it into park the day it made it back unto the driveway. It was difficult shutting the car off and taking the keys out due to the transmission not allowing it to even go into park. Now iv only put 10k on it since I left the dealership and this happens. Pretty upset about that, and on top of that I'm mad at myself for not looking at the reviews. Now the vehicle isn't worth a damn thong for trade in purpose and most dealerships are aware and won't give a great trade in value, leaving you extremely upside down in your loan. Try getting out of an MDX! Terribly difficult! I will be bugging Acura until this car is in a scrap yard 20 years from now. They will know my name! I promis to haunt those a$$holes for the long haul until they make this right or help fix this car because I will run this thing until it can't be run anymore! Sadly because of Acura and their pathetic manufacturing that won't be as long as I'd have hoped for!

That is not entirely true. The parts in the MDX transmission that have been failing and causing the problem are consistently the same part, the same assembly - the torque converter. Yes, all moving components cause friction but, with correct lubrication, the heat buildup is mitigated, minimized and reduced to the point that the components are capable of operating to their designed parameters, without time limits.
Friction is not the problem but the fast heat build-up due to a HIGH friction coefficient and abrasive properties will cause the performance of the torque converter to become poor and shorten the durability of those components with continued operation once the HIGH friction condition is experienced.
The problem is one of design. The torque converter is not receiving adequate lubrication with long term use or, is subject to be easily fouled, resulting in insufficient lubrication causing HIGH heat buildup and component failure.
More frequent maintenance can prevent this.

Methinks you be quite far off-base.
It is my understanding that it is the lock-up clutch portion, integral portion, of the torque converter that is/has failed, not the torque converter itself.
In order to provide the best FE most modern day automatic transmissions made use of the lock-up aspect of the torque converter as close to 100% of the time that is possible, bypassing the function, functionality, of the LOSSY torque converter as often as is feasible.
Then you throw in the extra stresses of having the rear drive system engaged a goodly portion of the time and you have a recipe for failure.

Hi 'washingtongc', I have a 2009 with the same problem at 40K miles. I took it to the nearest dealership and either they were unable to demonstrate it or pretended so. It will be helpful to know which dealership you went to.

After just having the transmission rebuilt on this gently-used and well-maintained vehicle, I learned how common this problem is. Very disappointing. After having bought four Acuras from a local dealer, they did not have the courtesy to reply to my complaint. They did not do the repair work, since their shop prices are way too high. This will be my last Acura. Some enterprising lawyer ought to explore the possibility of a class action suit on this.

I agree with you. My only recoarse is never to buy another Acura/Hoda product. Our next car will be a Ford.
