“On October 1, 2026 at approximately 5:45am, while driving my 2026 Acura MDX, I stopped at a red traffic light on a busy street. The vehicle's Auto Idle Stop system shut the engine off as designed. When the light turned green and I attempted to proceed, the engine failed to restart. The vehicle became disabled in an active traffic lane in the dark and I was unable to move it for several minutes. I attempted to restart the vehicle multiple times. It took several attempts to fully the shut the vehicle down and restart it before I was able to actually restart the car and resume driving. …”
