I have a 2015 JK Willys and I'm getting a weird warning on my dash. My jeep will give me a warning Bing, then all at once, my speedometer will drop or fluctuate (even though I am still going freeway speed), the traction control skid marks light will activate, the hill decent pictograph will also light up and the red brake indicator will light up. While all of this is going on, the jeep will Bing. The dealership replaced the brake switch, but no luck. Can anybody help me? I'm starting to loose faith in my dealership!
