The auto shut turns the car off at a stop light and then the car will not restart. It usually needs a jump. The problem has been happening for three years in the winter. The battery has been replaced four times. I have traced to the issue to an overload of the electrical system. The alternator is not capable of pouring all of the devices in the car and thus the battery drains. If I run the heated seats and steering wheel, the battery will discharge within 30 minutes even if the car is driven at highway speeds. I have been stalled in the middle of intersections several times. The autostart feature needs to have the option to stay dis-engaged when the car is shut off. It is unsafe to have the car fails to start at stoplights or when trying to pull into traffic. The electrical system is designed improperly. Do the math. The load from the electrical accessories, two heated front seats, two rear heated seats, heated steering wheel, heated mirrors, heated rear windshield will easily overload the power of a standard alternator. The vehicle needs a larger alternator and a larger battery (maybe dual) with isolation so it can start at stoplights.
The contact owns a 2016 Honda Pilot. The contact stated that while driving at approximately 55 mph, the vehicle stalled. The vehicle failed to restart and was coasted to the side of the road.

The approximate failure mileage was 1,038.
