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 won’t shift gears or the abs system activates by itself or the speedometer doesn’t work. This has been going on for almost a year now because there is no parts aviable to fix it. The dealer keeps saying it’s in engineering review but they been saying that for almost a year now. That’s how long mine has been acting up. My wife won’t even drive it with the kids in the car because she doesn’t know when it is going to act up. Luckly I only work 5 miles from my house so I’ve been driving it. If they know there’s 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.
