In owners’ own words

Power train mileage not reported 3.8 yr in service
While driving, in the middle of the high way, the car shuts off and stops and when restarted it wouldn’t go. Stopped, twice this month and three time total this year, on the Highway thank god no accident.
Power train mileage not reported 3.8 yr in service
Multiple times when I have come to a stop (traffic light, stop sign, etc.) my MDX has shifted itself into "Neutral" and it appears the engine has cut off by the battery power is still on, my MDX will not shift back into "Drive" or "Park"; I then have to press then "Engine On" button multiple times to get the battery power to shut off and then I can restart my MDX and then my MDX will shift into "Drive." I took it to my Acura Dealer and they said they checked it and there was nothing wrong and they also told me there had not been any recalls on my MDX.
Power train mileage not reported 4.5 yr in service
I was in RED light and Car went to Idle Stop. I got Green Light but the Car automatically went to Neutral mode and did not back to Drive mode when I changed. I put emergency light on but People do not have any patience and Horn me in the light.. I tried many times to put Drive mode and it did not work. After turn off/on the engine few times finally it worked. It was very scary if I would have struck in middle of the Highway with family it would be very bad. I called the Acura Service center they act like they did not aware of this issue. I have setup appointment this week for diagnosis.
