One problem related to horn assembly has been reported for the 2009 Jeep Patriot. The most recently reported issues are listed below.
Little by little the electrical to my car has been going. Im the first owner and first the front power windows, then the horn and then the lights stopped working. Then my car started stalling out of no where when I would accelerate. They say its the pcm but I never abused and always took care of my car.
