Auto Stop/Start Quit Working
2017 HSE Dynamic with 8,500 miles
The Auto Stop/Start function quit working a few weeks ago. I recharged the battery (disconnected everything from the battery posts first, then used a slow 5 amp charge) which fixed the problem. A week later it quit again so I recharged again but that didn’t fix it.
Very little electrical load this time of year — AC off, HVAC fan speed at 3, headlamps off, HVAC and electric defrosts off, seat HVAC off, recirculation set to auto, stereo usually on, and no accessories plugged in.
No other triggers are active; Not in Dynamic mode, not in Sport mode, in 2WD, paddle shifters not being used, seatbelts fastened, ambient temp 45-65F, all fuses good, drivetrain at normal operating temp, etc.
ASS (an appropriate acronym I'm starting to think) has a significant impact on my gas mileage. My average is 27.1 with it, 25.2 without so I'd like to get it functioning again. Any ideas?
