One problem related to brake light on has been reported for the 2015 Jeep Renegade. The most recently reported issues are listed below.
Sept. 27, the brakes locked up while I was driving about 40 mph! I was traveling west on old us12, just leaving chelsea, gaining speed. There were no cars around me, nothing in front, beside, or turning near me. There were no animals in the road. There was no reason for the brakes to lock up. I was driving a friend home, all she noticed was the the brake light came on. I very carefully and slowly drove my friend home and took the car to the dealership, I told them I was not driving the car until they figured out why this happened. It is not safe!.
