I have a 2020 Insight and have a safety question. My sister's friends both passed away from carbon monoxide poisoning because they forgot to turn off their hybrid (not Honda) after putting it in the garage. After the battery finally died it went to gas mode. Questions: Does the Insight do the same thing - go to gas mode after the battery runs out? If so, is there way to program it so it will turn everything off after a certain amount of time? I could not find the answer in the user manual.
Welcome to the forum. Overall, once the car is
Powered On in drive-ready mode, it stays running (EV/gas/hybrid) even after the key fob is removed from the car's proximity. The car won't turn off unless the power button is pressed, and there isn't a programming feature that Honda shares on this. (And as semi-related FYI, if someone steals the car while it's in drive mode and the key fob is no longer in the car, the car stays running until it's powered down.)
When the driver's door is opened (and driver's seat belt is unfastened) while the car is still Powered On, the transmission will shift itself to Park and a warning tone and message will display. From OM19 pg 460:
If the driver progresses further to exit while the car is still running (i.e.
key fob is removed from operating range while the car is still Powered On
and all the doors are closed),
loud warning tones sound both inside and outside the car. From OM19 pg 192:
If the car is only in
Accessory mode (vs fully powered on and running) and left in Park for 30-60 minutes, the car automatically turns off to avoid draining the 12V battery. However, this mode is likely maintained by EV only (vs gas). From OM19 pg 151:
