Go to Autozone and they can scan it for free it's probably a bad wheel sensor mine did the exact same thing but have it checked out anyway

 

. Or I forgot the Jeep will actually tell you the code maybe somebody else can chime in but it was like turn the ignition on 3 or 4 times and push the brake pedal but I'm not too sure

 

I had an issue similar to this, ended up being the negative battery terminal. Cinched it down and the gremlins went away.

 

All good advice.

1. Make sure your battery connections are tight. There should not be any accessories attached to the nut that is closest to the battery terminal. This is a cam nut and tightens the connection. If something is on that nut the connection can be bad.

2. Make sure your steering wheel is straight when the wheels are straight. If not, use the drag link to adjust. It's a 10 minute job.

3. Check the connections to the wheel speed sensors. Make sure the connector is plugged all the way in and there are no broken wires. This is especially true if you flexed your Jeep recently or installed a coil lift.

4. Post up when it is fixed so other members can learn from it.
