Sorry If this is being posted in the wrong place. I just got my 2012 jku out of the shop due to an ongoing abs issue. I keep getting thrown into limp mode. Iíve tried everything I can think of for repairs. Dealership I just took it to said I need a new master harness. Any help with this is much appreciated. I just changed out both rear axle seals and bearings. Also did the passenger side rear wheel sensor. Itís also throwing the cylinder 2 misfire. It seems to me like the dealership didnít want to deal with me on the head issue. Out of ideas. Hopefully someone on here can help me out.
