Acura MDX Shudder or Vibration While Driving at Speeds Between 35 and 40 MPH
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. - Visitor
A shudder happen when it's speed reach 50-55mph. - Visitor
Shuttering at low speeds, off and on. Not continuous, nor consistent, but obvious. - Ron T
shutter, grinding noise @ 35-45 mph... i bought the car used with a 87024 miles... i'm prettty upset - Visitor
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. - Visitor
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. - Visitor
Occasional vibration on country roads normally- havent noticed it on the freeways/highways - Visitor
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. - Visitor

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. - Visitor
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. - Visitor
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. - Visitor
Periodically for the last 4-6 months my engine
Would vibrate for 10-20 seconds when driving
Between 30-50 mph. Worried it's going to transmission - Visitor
first show me p/t temp sign and it can not go forward, it go for 100 feet and it makes a noise, and the I park it for a while and try again it go for 1 mile and I park it do exercise for 3 hours and I drove it 100 feet and the can not go forward. - Visitor
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. - Visitor
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. - Visitor
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 - Visitor
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. - Visitor
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. - miksco72
