One problem related to brakes failed has been reported for the 2015 Jeep Wrangler. The most recently reported issues are listed below.
While slowing to a stop from very low speed, on a paved city street, the brakes failed. Pedal was all the way to the floor, and seemed as if the Jeep accelerated slightly, and the abs was possibly activating and releasing? causing minor damage traffic collision with stopped car in front of me. I am a retired traffic accident investigator, and was not distracted, I could not recreate the same malfunction after the collision.
