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.

    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.

    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.

    Transmission is junk. Do not buy any Acura/Honda vehicles mated to a v6 from 1998-2004. This includes but is not limited to Honda Odyssey, Honda Accord, Honda Pilot, Acura Mdx, Acura Cl, Acura TL and Im sure others with the same transmission. Honda Corp. has managed to cover up this flaw along with many other flaws in past years. They are being sued for 70 million by the US government as Im typing this paragraph. I vow to never purchase another vehicle from Honda/ Acura again and I urge anyone reading this to do the same. Good luck and God bless. - Richard
