I too recently purchased a 2009 MDX and am having issues with the RPM fluttering and hard steering. I brought it to the dealership and they said that they don't know how to fix it!!! This is an Acura Dealership.... Acura of Escondido!
I also received both letters from Acura regarding the torque converter and steering problem, but this dealership declines to work on it. They said, "I see it, but don't know how to fix it!"
Have you had any luck getting your MDX fixed?

Both well documented problems.
There are TSBs out there and Acura has increased the torque convertor and power steering pump warrenty.
I got mine done at Acura of Kearney Mesa about a month ago. The steering feel is much better and after the TC software update its a new machine.

How did you contact them and what did you say to them?
#912 of 995 2009 MDX Torque Converter Recall
Nov 02, 2012 (7:33 am)
I recently purchased a pre-owned 2009 MDX with 37K Miles. It is still under the 'bumper to bumper' warranty. After noticing a noise in, what I thought, was the transmission when driving slow at 25 - 30 MPH in my neighborhood. The noise sounded as if I was driving along the rumble strips along side the highway. Albeit somewhat subtle compared to the highway noise and subtle vibration.
After explaining to the dealership they said this is a recall. The first step is to "update" the computer system. This should work depending on how long the torque converter issue has been happening. If the computer system update does not fix the issue they have to contact Acura HQ to look into having the entire Torque converter replaced. This is what is currently taking place for my car as we speak.
Again, covered under warranty/recall. This sounds similar to some of the other posts.
I'm in Charleston, SC and took my vehicle to McDaniels ACURA.

This may be very bad news. Acura switched the MDX from the VTM-4 F/awd system to the SH-AWD system to combat this very issue/problem. Didn't the switch occur prior to 2009?
I have assumed having both the front and rear axles in "drive" mode, even if only during acceleration, on a highly tractive surface is at the core of the problem so the "update" may serve to lessen the use of the rear drive capability.

All modern day passenger vehicle automatic transissions, ALL, industry wide, are now making "liberal" use of the TC's lockup clutch to improve FE. So the lockup clutch must be much more ROBUST vs yesteryear since it is now used much more of the time to bypass the lossy TC.
These days the only time the TC is unlocked is under acceleration, stopped, if the roadspeed is too low, or if brakes are applied to a level that would stall the engine if the TC remained locked.
Then you throw in the additional heat/stress on the driveline components with the rear drive engaged under acceleration on a perfectly TRACTIVE roadbed and you have a recipe for premature failure.
So it is entirely possible that the TSB reduces the use of the lockup clutch in order to extend its service life which in turn would result in lower MPG.

So what you are saying is that Japanese are better liars than Koreans? Couldn't agree more. At least Kia came out admitted fault and apologized.

The Japanese culture does NOT allow for admission of fault therefore most certainly NEVER an apology.

You're absolutely right, they usually kill themselves over shame. Well i hope whoever did this at Acura commits harikari ASAP!
