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.

    Shuttering at low speeds, off and on. Not continuous, nor consistent, but obvious.

    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.

    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.

    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.

    Mine started slightly about 2 years ago and now it's more often and my Maintenance Required light flashes when I start the car. I'm trying to find out how much it will cost.

    I have the same issue with our MDX with 62000 miles. The Acura technician said they couldn't replicate the issue for the 5 minutes they did a test drive. I mentioned it doesn't happen all the time but is very frequent. I refused to accept the fact there isn't an issue here and was very vocal about Acura spending more time with the vehicle to replicate the issue. I asked they keep the car for several days and provide a loaner vehicle (which they are doing). I know the warranty expires here at 70K miles so I'm not giving up on getting this repaired even though I was told to take the car home with me and monitor it over time.
