I own a 2020 Honda and I wish this was true. I have left the car on for 8+ hours before while being miles away. I’m in shock this wasn’t addressed and it’s my biggest gripe in the car.
For remote start, my 2018 Civic shut off after ~10 minutes. According to the sibling comment, their 2021 was similar. Did you have an aftermarket remote start, or was it started using the actual ignition switch in the car in your case?
I own a 2021 Honda and it definitely shuts off after 10 mins for me.
