Automatic Transmission Torque Converter problems of the 2011 Acura MDX

While leaving a parking lot and coming to a stop prior to entering traffic, the car lurched forward while braking. This has occurred 3 additional times since that initial episode. Concurrently, the transmission began to shift roughly. I experienced "micro lurches" while accelerating and decelerating; under 40mph. These lurches while shifting are not present when speeds exceed 55 mph. The Acura dealer initially indicated there were no problems as no computer anomalies were detected. After multiple complaints, Acura sent a technician to investigate. He experienced the "micro-lurches" on a test drive with me and after consultation with Acura, agreed to replace the torque converter. However, they maintain that there is no computer data to explain the unanticipated accelerations I experienced and therefore Acura does not acknowledge that there is a problem. I believe that these intermittent episodes of unanticipated accelerations represent a safety problem. During my last conversation with Acura (800382-2238 x 115185), I was informed that there was nothing further they plan to do. I indicated that I would be filing a complaint with the NHTSA.
