Another 2004 MDX transmission issue.jutter occuring between the speeds of 25-45 mph.dealer claims this is not under warranty any longer(100,000 miles on car) and there have been very few complaints on this problem.after taking the issue of needing a new transmission to corporate, I was told they would cover only a portion of the cost. My portion would be $2500. This is absurd. Acura knows full well that a problem exists and should stand by their vehicles. They have certainly lost me as a three time buyer of their vehicles.

Shuddering in transmission between 35mph and 45mph and lack of power. Took it to the dealer and they said Honda has a service bulletin on it.

I have a 2004 Acura MDX. There are about 77,000 miles on it. Vsa, vtm-4, ABS, and airbag lights keep flashing. So I took it to my Acura dealership and they told me that after diagnostic that the rear differential failed. I believe there is something wrong with the wiring of all MDX in or around 2004. There has been numerous reporting of rear differential failures in 2003 and 2004 Mdxs. Acura should take a look into this and maybe do a recall. This is very dangerous because the transmission makes a loud noise and slows down when you are driving almost as if the transmission was about to go out.

After backing out of my driveway and shifting the car into D5 the transmission would not engage and was completely slipping. After shifting to a lower gear I was able to get the car to drive and then shifted back into D5. Upon slowing and then trying to accelerate again the transmission again completely failed to engage and hat to be shifted into the lowest gear to re-engage the transmission. Also, on several occasions while trying to pass other vehicles the transmission would again completely slip. Also at points where I would enter traffic from a side street or parking lot as I have tried to enter traffic at an opening the transmission would fail to engage which has created very dangerous situations where we have almost been in a very bad accident.

2004 Acura MDX torque converter issue. I can feel/hear the vibration/shudder/grinding between 20-50 mph while maintaining the steady speed with light load. The same issue happened once when the vehicle was at around 45000 miles. The dealer replaced the torque converter under warranty. However, the same issue came back at around 75000 miles until now at 93000 miles. It was only noticeable at around 30 mph, but now can be noticed between 20 and 50 mph.

I went to drug a store and was in a hurry when I parked the vehicle. I left the car in "drive" as I was in a hurry and didn't notice. I was able to turn off the ignition and remove the key, which didn't register to me as a problem at the time. When I came out of the store, I found the vehicle had rolled backwards and struck another parked vehicle, causing approximately $2200 in damage to the other vehicle. Minimal to no damage to my vehicle. When I got home I was able to duplicate this situation.
