With the newer models, 2010+, Acura is probably playing a numbers game.
The failures will likely be primarily south of the snow belt, and for MDX drivers with somewhat of a lead foot. Lots of time with the rear drive engaged, driveline STRESSED, and mostly on highly tractive surfaces.
On the flip side those north of the snow belt will really appreciate the wintertime roadability, driveability, using the revised, more robust F/awd performance, rear drive control firmware.
Again, I would much prefer a system that could be switched off thereby avoiding the needless, unwarranted, stressing of the driveline when traction conditions are KNOWN to be "solid".
But the public, overall, seems to be buying fully into this automatic PART-TIME F/awd design.

I have the same grinding issue with my new used 2008 MDX. I took it to our nearest Acura dealer to get them check out (3x already) along with the P0847 code that was on the diagnostic info. They are aware of the problem but in total denial. They'll turn you away if you're not persistent. MDX is not cheap, so we all deserved a quality car in return. We should all call the Official Acura tel. # (1-800-382-2238) to file a complain. Everyone seemed to have the same issues as far back as I can read in this forum - TRANSMISSION related issues (the grinding/hesitation noise). ACURA needs to recognize that this is a major transmission design issues (whether the torque converter, sensor, ect.).
In all the cars I had, MDX is the WORST and it's not worth the money. The biggest mistake car purchase I've done so far. GAS MILEAGE also sucks!

She said more than 500 owners have contacted her through her website, DontSettleWithHonda.org, which explains how Peters filed her lawsuit against the automaker.
Peters said she planned to reactivate her state law license so that she can represent other Civic owners in litigation against Honda.

Took my 2010 MDX for service and one recall notice. While I was there I was informed that there was another recall for the transmission fluid. Long story short, Acura is fully aware of the problems addressed here in this forum. I too complained to the dealer regarding the delay/hesitation between gears. The dealership kept insisting this was normal and I even test drove two other MDX (2010 and 2011) to see if this was true. According to my service rep this change of fluid should help with this delay/hesitation. Recall notices are on their way to 2010-2012 owners. Feel free to contact your dealership. I have not received mine however the dealership was very proactive in getting it serviced and corrected while I was there on March 10th.
I am debating trading in my car before something major happens. From what I continue to read in this forum I do not want to wait until it's too late.
Good luck to us all!

"..I am moving on to Lexus..."
From the frying pan and into the FIRE.
I have now been closely watching, monitoring this FWD to F/awd issue for nie onto 12 years. Insofar as I know, can tell, there NO manufacturer that has as of yet solved this "equation" suscessfully.
With the advent of the introduction of the '01 RX300 Lexus was forced to, HAD to, totally abandon the new F/awd system that they initially introduced with the '99 RX300. Even with these changes, major changes, it wasn't until the adoption of DBW with the new RX330 that the driveline, mostly transaxle, failures declined to an acceptable (to Lexus) level.
In the meantime RX300 owners were left without a functional F/awd system. In 2010 Lexus switched to an entirely new F/awd system, the one Ford, Escape/Mariner, had earlier encountered so many problems with. Ford is solving their problem by simply dropping the product line.
It remains to be seen whether the new RX350 F/awd system will pass muster. Lexus has added an ability to lock the system in "awd" mode but my guess is that will soon be discontinued, if that isn't already in the works.
Driver's in the general case CANNOT be relied upon to make judicious, reasonable, use of that "awd" functionality, and most certainly cannot be relied upon to always remember to turn it off once the slippage condition has passed.

Mar 20, 2012 (1:20 pm)
My MDX is 146k miles and starting to give me the "Shuddering" sound when driven between 25-45 MPH. Today I had Acura dealer look at it for $ 125.00 charge and said it is the Torque Converter issue and plus few others, here is the list:
Torque Converter: $2700.00
Front and Right side Engine Mounts: $ 550.00 (with TC change)
I declined the work for now. I am thinking calling AHM and also looking for any firm willing to do a Class Action. If there is a Class Action already in works ..please let me know..Thanks

You'll need a new/rebuilt transmission; $4,500
Also, two motor mounts are broke, not one. If you never had the timing belt or spark plugs replaced at 110k miles, it's overdue. You'll also need new front lower control arms & balljoints.
I have 160k miles my 2003 MDX and it's very well maintained. I'm speaking from experience. I forced the transmission issue with our dealer at 110k miles and they got Acura to pay 90% of they trans. cost.
You'll just have to decide if it's worth keeping.

What did you end up finding out was wrong? What was wrong with the transmission causing that grinding noise? I have experienced a similar issue with my 2008 MDX where it has on a few occasions made that noise after driving on the highway for a couple of hours. Like a grinding/whining noise.
