Ok... with a flashing odometer, you need what is called a proxy alignment. That's fancy for computer reset (kinda), and this needs to be done at a dealership... It can be done at home, but you need a few things including a rather complex program that requires knowledge to run. You also need a tool that plugs into the car's OBDII port, to be able to use the program. The majority of us will get the proxy alignment done at a dealership. The goal is to allow different key electronics of the Jeep to talk to each other again.Yes, it is! It was having a problem starting recently.
