NHTSA Complaint #11621400 — 2020 ACURA MDX

I came to a stop at a stop sign. The start/stop feature activated and the engine shut off. When I lifted my foot off the brake, the engine did not restart (as it's supposed to), and then vehicle automatically shifted itself into neutral (without any of my doing). I put the emergency flashers on to alert other motorists, hoping to avoid a rear-end collision as I was stopped in the middle of an intersection in rush hour traffic. At this time, the battery light illuminated. The engine light illluminated as well. I had to forcefully and unusually push the brakew pedal towards the floor as the vehicle was drifting backwards. At this time, the vehicle would not shift into park. Then "PARK" illuminated, so I attempted to reapply the brake hoping that when I let up from the brake the car would start again (like the usual procedure). The vehicle then shifted into park, but the engine had not restarted. I pressed the on/off red button to follow normal procedures for turning the vehicle off. With my foot remaining on the brake, I pressed the off/on red button to start the engine as usual and the engine finally restarted. Afraid for the safety for myself and other motorists, I put the vehicle into drive and I pushed the button to stop the stop/start system from engaging. No codes generated during this. This is a safety issue for several reasons. First, I was stuck in the middle of a busy intersection where a large volume of cars travel through each day. It was rush hour, so the roads couldn't be more filled. Someone coming around the corner who might not have been prepared to stop could have hit me. Likewise, I could have been hit while in the intersection. Secondly, once the vehicle failed to turn back on, the Washington Grove (Montgomery County Fire and Rescue Services - MCFRS) was responding to a vehicular file nearby on I-270 and had I not have been able to move in time, some of their vehicles likely wouldn't have made it through because my vehicle was blocking the lane.
