I picked up my new Jeep Renegade Limited 4x4 Sept 18th with a build date of July 2015. (ordered it in March 2015) The front collision warning system is not working. I have changed it from near, medium, and far still not getting any warning. Off to take it in to the dealer to have it looked at. Any idea's? Is it a software thing? I love my Renegade, but want all the safety features to work.
