Automatic Transmission Control Module problems of the 2017 Acura MDX

On [xxx], while driving from orlando, FL to atlanta, GA, I experienced one of the most terrifying moments of my life. I was traveling on the freeway at approximately 80 mph, in lane 3 or 4, when my vehicle suddenly began to hesitate and lose power without any warning. In that moment, fear and panic took over. Cars were flying past me, and I could feel my truck rapidly decelerating. I immediately turned on my hazard lights and began honking to alert other drivers, praying they would give me space to move over. Thankfully, I was able to carefully navigate across lanes and reach the far-left shoulder. Once I got into the acceleration/deceleration lane, the vehicle suddenly lurched forward and began accelerating again—completely on its own. I knew I couldn't risk staying on the road, so I exited at the next ramp and pulled into a gas station, still shaken. After refueling, I attempted to restart the truck, but it would no longer shift into drive or neutral. The truck was stuck in park and completely inoperable. A roadside mechanic responded to my call for help and made several attempts to restore mobility, but nothing worked. I spent the evening stranded and alone, unsure of what to do next. The following day, [xxx], I had the vehicle towed to Honda south near atlanta, GA. After inspection, I was informed that the issue was a complete transmission failure. In addition to needing a new transmission, the vehicle also required replacement of critical sub-assembly components, including the transmission control module (tcm). This situation was not just a mechanical failure—it was a serious safety event that put my life and the lives of others at risk. I’m still shaken by what happened and deeply concerned about how such a failure could occur so suddenly and without warning.

Driving east on interstate 20/59 10 miles east of meridian, ms November 17, 2021 around 2:00 pm. A lot of trucks on the road. Had speed control set at 69 mph. Came up behind a semi doing about 65, pulled over to the left lane to go around him. When I got about half way all of a sudden all hell breaks loose. Vehicle goes in into emergency stop with lights flashing all over the dash. Vehicle brakes to around 30 mph within a couple of hundred feet with semi's and cars beside and behind me. Finally got the vehicle over to the side of the rode without and accident. (a miracle inself). Code dtc p0716. After about an hour of shutdown, started engine and all messages were gone. Took it to the Acura dealer and they, evidently, updated the tcm software. I had not been notified that it needed and update which is negligence on Acura. This incidence could have been a catastrophe with possible deaths. Now my wife is really afraid to drive this vehicle.
