One problem related to alternator/generator/regulator has been reported for the 2015 Jeep Patriot. The most recently reported issues are listed below.
When driving the car there was a periodic jerk and than it began to loose acceleration. No matter how much I pressed on gas it wouldn't go and than it just died. They thought it was battery so we replaced battery and alternator. Still having issues with the periodic jerk and the battery light now comes on and off. This needs to be looked at.
