2020 Honda Passport ELECTRICAL SYSTEM,ENGINE

Car shuts down and does not restart. Also goes to neutral and does not allow car to be steered. Also seems to be related to auto restart.

When I attempted to accelerate as the light turned green, the engine failed to restart. The car was immobilized in the left-hand lane, hazards on, and shifted itself into Park. Multiple attempts to restart failed. After several minutes and repeated actions (cycling ignition, exiting and re-entering the vehicle), the car finally restarted. Safety Concern: The vehicle was disabled in active traffic, creating a hazardous situation for myself, my passenger, and surrounding drivers.

The Passport is equipped with an auto stop/start engine feature. In the last week, while stopped in traffic in the roadway the engine shut off, but did not turn back on causing the car to stall in traffic for several minutes before I was able to restart it. The vehicle shifted to neutral and wouldn't restart until the power was fully off and the door was opened and closed. Both times I was stuck in a travel lanes for approximately 3-5 minutes.

The contact owns a 2020 Honda Passport. The contact stated while attempting to stop at a red light, the vehicle lost motive power and stalled. The vehicle was restarted after the third attempt however, the failure persisted. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the starter needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 31,000.

With the Idle-Stop activated, the engine shut down while stopped at a red light. However, when I disengaged the brake and tried to push the gas pedal to start, the car did not restart. It went "dead." I had to attempt to restart the car, and it took multiple attempts to get it to restart. I ultimately had to put the vehicle in park and then re-start the engine manually once the 2020 Passport "re-set" itself. This was dangerous, as I was in a very active intersection at dusk/night and the Passport became hard to see as the electrical system + engine shut down and would not restart promptly with cars trying to go through the green light.
