I would venture to say that as long as you drive the vehicle as intended to maintain the battery you should have no problems. Maintaining an AGM battery in a vehicle isn't all that tough. It just takes a little driving time really. Short little 1 or 2 mile trips don't give the vehicle time to charge up the battery. I'm 6 days short of 3 years into the OEM battery on my 2020 Touring and the SOC is 12.6 after a charge and 8 hour rest before testing.You know I think you're right guys....I should at least drive the new Pilot around for a week or so when I get it without turning off auto start and make sure it is really such a big deal to me. Maybe it isnt as you said
If you don't like the Auto Idle Stop feature, there is alway the option to turn it off with your free idle stopper device.
