Unknown component failure on 2019 Honda Passport. While operating the vehicle, the engine shut off and automatically placed the vehicle in neutral. The battery light appeared on the dashboard, and instructed, ‘To start engine: Brake + Push’. The vehicle would not allow me to press the start button unless placed in park, however, the vehicle would not allow me to select park while the engine was off. After a few minutes, I was able to place the vehicle in park, but the engine would not immediately start upon pressing the start button. I then had to manually reset the vehicle by pressing the start button three times before the engine would turn on again. This issue has occurred three times over a span of three months. Once while I was parked. Once while I was operating on the highway, thus posing a risk being rear-ended at a high speed. And once while I was operating through an intersection on the main road, again posing a risk of being rear-ended or T-boned. During these times, the vehicle was rendered inoperable until it was eventually restarted. There were no warning messages or other symptoms of the problem prior to the times of failure. It is noted the issue seems to present itself while the speed of the vehicle is decreasing. For instance, while slowing in traffic on the highway and on the main road. The issue was brought to the attention of the Honda Service Center on two separate occasions. Both times Honda was unable to replicate the issue or identify the component at fault. Honda stated that the vehicle diagnostics and computer system presented no codes or record of the malfunction. The issue remains unresolved.
