Transmission failed despite the car having the factory recommended service for the transmission being performed at 60k and 89k. The transmission dropped into 2nd while on the highway at 65mph. Upon investigating it was found the car was part of a Class action due to transmission failure, but I was not eligible since the car was out of the extended warranty period.
Transmission failed at 60,000 miles. After hearing that there had been a recall of my vehicle for transmission problems, I called Acura. They told me that the recall did not affect my vehicle (according to the VIN #). They agreed to check to see whether it would be covered under the recall but the process they suggested would take several weeks to determine whether or not they would cover the problem. I had my vehicle repaired at my expense. I now see the VIN #'s that were affected and it looks like my vehicle should have been part of the recall.
