Had our Jeep for about 1 month now, we have had the center dash that shows speed go black twice while driving and probably about every 5 times the radio seems to cut in and out almost seems tied to accelerating at times. Also last 2 days now when starting in the morning I noticed the brake pedal is very stiff and requires a lot of force to get it to start. Ive read many places about the ESS battery possibly being the issue but anyone else had these issues
