2016 Trailhawk here. I had not started my Renegade for about 10 days. When I got into start, pressed on the brake then hit start button, the brake pedal was very hard to push down. I really had to push down to get the brake pedal to move down enough to start the engine. Is this normal, something I need to worry about. Does this happen when the vehicle is not started for 10 plus days.?
