Automatic Transmission Control Module problems of the 2020 Honda HR-V

While stopped at a traffic signal, the vehicle failed to restart when the light turned green. On another occasion, the vehicle stalled during operation and would not start. The engine would crank but there was no ignition. This created a safety risk because the vehicle was disabled in traffic and unable to move out of the roadway, increasing the risk of a rear-end collision or other crash. The vehicle was towed to a dealership for inspection. The dealer diagnosed a failed powertrain control module (pcm). The diagnosis indicated no spark and that the ignition coils were not receiving signal, although the crank sensor signal was present. The pcm was replaced, and the vehicle started and operated normally after replacement. No additional wiring, fuse, or grounding issues were identified. There were no prior warning lights, dashboard messages, or drivability symptoms before the failure occurred. The failure happened unexpectedly at approximately 52,889 miles. The replaced pcm is available through the servicing dealership if inspection is requested.
