Shudder or Vibration While Driving at Speeds Between 35 and 40 MPH on Acura MDX

A shudder or vibration may develop while driving at speeds between 35 and 40 MPH. Our technicians tell us this condition is commonly caused by a failed automatic transmission torque converter. It is recommend to replace the torque converter and install an updated powertrain control module (PCM) to correct this concern.

I noticed the 'shudder' described here and brought it in to the dealer and told them of this noise. On first visit dealer could not find a problem. After driving some more I detected that this 'shudder' occurred in the 40-50 mile range and brought the car back to the dealer. After two rides in MDX 2nd mechanic finally correctly diagnosed the problem ( one would think that this would be the first thing they should suspect). When paying $1800 repair bill ( that's with 'discount') I complained that the internet had numerous complaints about torrque converter problem and that quite a few customers did not pay for this defect repair. I also voiced my concern over possible future transmission problems. The manager disregarded the numerous internet documentations and claimed the model had no transmission issues. Months later I was at my local mechanics shop with another car & I described the MDX 'shudder' and he immediately told me that it was a torque converter without my telling him anymore. I was not happy with the stonewalling or lack of knowledge that Acura showed in dealing with me. I'd prefer to have my car serviced by Acura however this kind of treatment has driven me away.

A shudder happen when it's speed reach 50-55mph.
2006 Acura MDX135,000
Shuddering usually between 25-40 mph when slightly depressing gas pedal, cruising or slightly accelerating. Shuddering stops when letting off the gas pedal or by de-pressing to accelerate quickly. I called the Acura dealership and my vehicle did not have a recall for a Powertrain Control Module (PCM) software update to resolve issue. Acura technician mentioned it could be the torque converter or another software update needed.
Shuttering at low speeds, off and on. Not continuous, nor consistent, but obvious.

It shudders or vibrates from time to time. Dealer changed the tranny fluid and it would go away for a little while. I think there should be a recall for the transmission.

Occasional vibration on country roads normally- havent noticed it on the freeways/highways
2007 Acura MDX107,000
After recent software upgrade for the transmission recall, I am experiencing noise and shudder after car reaches 40 + ml/hour. The noise is disappearing after 75 + ml/hour.
I have had this shudder vibration in my MDX since I bought the vehicle. I took the car back, but they couldn't duplicate the noise and said they didn't know. I have lived with that happening from day one and now I see a whole bunch of other complaints about the same thing.
Vibration at 35 /40 miles
2002 Acura MDX120,000
2002 MDX upshifts from 4th to 5th gear at 35-45 mph, resulting in lugging, shuddering/vibration and a LOUD, annoying growling/grinding noise. The problem is absolutely gone if I shift to D4 (not allowing it to shift to 5th gear) or if driving over 55 mph (and 5th-gear rpms > 1600).

Shudder or Vibration While Driving at Speeds Between 15 and 20 MPH
between 40 and 60 mph
2005 Acura MDX138,000
Have the same shutter / washboard sensation when driving at city speeds. This just started last week. We have owned since new and have religiously maintaned the car at Ron Tonkin Acura. Very dissapointing as we researched reliability at the time of purchase and the MDX was highly rated. I will report back when we have a diagnosis and repair. Have read other threads, stating this is a safety issue as the drive wheels (front) can all of a sudden lock up and not spin while driving car. If this happens on a freeway, imagine what would happen.

Exactly the same complaint. 35 to 40 miles an hour. Shudder or Vibration. Started doing it following a transmission fluid change. It was noted at the time of the fluid change approx. 300 miles ago that there was a accumulation of metal shavings on the magnet attached to the transmission drain plug From the looks of these complaints, a T converter looks to be in the near future. Currently not driving the car for fear of collateral damage if the converter were to come apart. In my opinion, Honda/Acura should provide the parts for this failure. They certainly have been made aware of it from the looks of the numerous complaints!! In my opinion they should have recourse on the vendor.

I have a 2004 MDX which has been no issue until last week when the transmission showed vibration around 40 MPH. Now it wont's even start. Is there a lawsuit ongoing? If yes, I would like to jump in.

At low gears there was a tendency for the shifting to be rough. This issue was most prevalent when accelerating/decelerating through the gears slowly. When going up slight inclines where deceleration was occurring, the transmission would oscillate between gear until a significant throttle response was provided. The dealer stated today that the torque converter needs to be replaced.
2006 Acura MDX160,000
Problems documented internally thru service calls, oil changes, tire rotations at Acura dealership for years. Car sold by a dealership to auction & onto me through another used car dealer. Drove 2006 MDX 1,000 miles, to around 160,000 then heard noise in right front car area, when going over bumpy road. Checked & found car sold with 2 open recalls, airbag & shift interlock both safety hazards. Took to another Acura dealership for maint. evaluation & fixing recalls. I Found many technical service bulletins on fixing various serious problems that were never done. Now, due to under reporting actual customer problems/trends as required legally; I need torque convertor, new transmission, motor mounts broken, oil pump leaking, front struts needed etc. etc. $9,000 cost. plus loss of price paid for car. Beware problems have continued from models 2000 & on. Manufacturing design responsibilities to inform, fix, report, then reimburse customers. Honda/Acura fined & lost several suits exceeding 200 million & rising. No remedy yet for me & others who had to pay for same problems repeatedly, when TSB's indicated real causes for customer problems & remedies never offered owners unless they find out on their own.
