It was a rainy day, she had our kids in the car on the way to a soccer game. I called off work with an emergency, drove an hour to where she was and scanned the car.

    The auto-stop feature on my 2019 Acura RDX has resulted in my car abruptly shutting down twice now -- today it happened when I slowed to a stop at an intersection. Basically, rather than just shutting the engine off while idling, it shuts of the electrical (dashboard and infotainment -- all systems) and engine and then immediately restarts with the car in Park. There was no warning sound or light prior to the car turning off and restarting. Obviously, it is very dangerous…
