I was driving on county road about 45 mph battery light came on then abs light then message service anti lock brake system, engine and brake light they stayed on till I got home there was also a very low humming noise when I turned off car it would not start again. In morning it started I turned it off and it will not start again. Battery and engine light on. 11/19/15 recalls for ignition switch,and reprogram final drive controller module were performed.
Vehicle displays esp (electronic stability program), bas (brake assist system), abs (antilock braking system) lights in cluster, as well as service 4wd system. While these lights are active, vehicle becomes unsafe and brakes while cornering under acceleration (without touching the brakes!) and has resulted in loss of control. Issue has been repeatedly reported to dealerships and manufacturer (10 visits for this issue spread across 2 dealerships, and 4 cases have been opened with Jeep directly). Issue continues to be diagnosed as a failed brake light switch, and switch is replaced. New switch works for 3-6 weeks before failing again, rendering vehicle unsafe. One example of this issue resulting in the vehicle loosing traction occured in November 2015 while going on a circular highway entrance ramp with the warning lights illuminated. Half way thru the turn, while gently accelerating, the rear brakes completely locked up causing the vehicle to skid onto the muddy shoulder. In January of 2016 a similar incident occured while going up a snowy hill (road curves while going uphill) resulting in the vehicle loosing traction and going into a snowbank.
