I have noticed over the last few weeks that my speedometer is off by a few miles per hour. When I am going 75 the needle shows 80. Also the digital trip miles is working in conjuction with the incorrect needle readout. I know this because the aftermarket GPS shows my speed and the tenth value is a little off. Also when I go through the radar speed readout through the toolbooth shows I'm going slower than what my needle shows.

With this issues it will make it seem like I have more mileage than the X has really traveled.

Thanks all.
