2007 Jeep Liberty

Electrical problem
2007 Jeep Liberty 6 cyl Four Wheel Drive Automatic 60000 miles

My 2007 Jeep Liberty Sport has a problem where the speed that is being displayed is approximately 4 mph greater than what the vehicle is actually doing.

I've confirmed this by using my GPS, a chase vehicle, and those speed signs that you see occasionally. Each of these confirm that I'm approximately 4 mph off what my speedometer says.

Is this an easy fix by the dealer's car service center? Or should I just live with it since it might prevent me from getting a ticket?
