2017 WK2, 3.6L, 36k miles and have had on and off issues with the ESS warning messages and lights for a long time. I say on and off because it will happen for awhile, and then go away for a few months, and come back, and go away etc etc. It's been gone for several months, but now it's back, along with a "Stop Safely Vehicle Will Shut Off Soon" warning. My battery voltage on the dash gage is usually all over the place from 13.9 down to 12.7 and everywhere in between... constantly. Rarely... Stop Safely Vehicle Will Shut Off Soon
