This vehicle along with many others jeep wranglers have an issue with the abs control module. It has a code for internal processor fault. Some days the vehicle is fine and others it acts up and it wont shift gears or the abs system activates by itself or the speedometer dsnt work. This has been going on for almost a year now because there is no parts aviable to fix it. The dealer keeps saying its in engineering review but they been saying that for almost a year now. Thats how long mine has been acting up. My wife wont even drive it with the kids in the car because she dsnt know when it is going to act up. Luckly I only work 5 miles from my house so Ive been driving it. If they know theres an issue with these modules they should be doing something faster to fix it or there should be a recall. Something needs to be done.
