There is some concern about torque converters in older MDX vehicles, but now this goes forward to the 2010 model. At about 35,000 miles, my vehciles began to hesitate and shudder when it was necessary for the transmission to change gears. I read some Twitter reports which gave me reason to take my car to the dealer. They road tested the car and agreed the torque converter needed to be replaced, covered by the warrenty. They also told me they had replaced converters on four other 2010 MDX vehicles. The job takes about two days as the transmission must be lowered to replace the part. There is noticable difference now. My dealer was excellent in how they handled the matter.
Acura loves gadgets, but they might ask what consumers want. Their lack of response to this is now amusing.
