We actually disconnected the auxiliary battery in our Chrysler Pacifica because we were sick of stop-start. We recently rented a GM Terrain for a trip, and it had NO defeat for the stop-start system. Very annoying, and total BS about improving gas mileage. It’s carmakers attempting to scam the EPA.
It’s a totally worthless setting/option.
If you have an in-dash info-tainment screen, there should be a way to access ‘settings’, and get to the menu line item to disable it. I don’t know what yours would be listed under, but probably the ‘driving’ category. At least I’d think so... but one never knows.
