'19 Trailhawk, 18mo. in service with 26.6k miles. Cold start in garage;engine immed shut off; engine immed fired up on restart; screen filled with the ESS fail text message. Drove about a week with warning light on but no drive ability issues. Had good service experience - 1pm service appointment; out the door about 2:30 with new aux batt installed. Not pleasing to hear service advisor commenting 'we go thru quite a few of these batteries'
