Does anyone else's speedometer seem to be way off? In comparison to my GPS (which is assume is accurate?) my speedometer is off by about 10%. If I show 70, the GPS shows only 63. What really bothers me is that I'm chewing up warranty 10% faster than I should. Does anyone know how to fix or is this a dealer thing?
Thanks!
Speedometer accuracy?
My speedo is off but not as much as yours. An indicated 70mph is really 68 mph.
The funny thing is that the average speed reading is spot on. So the question is what info goes to the odometer.

Mine was more like Sluggo's, low by a couple of mph. Put bigger tires on it and it's VERY close to right now. What size tires do you have on yours, LPSISRL?

I've noticed this as well. My speed is higher on the cluster than the GPS.
Yes, I think GPS is accurate. It has always matched the speedo in my other cars.LPSISRL wrote:My SLS has the stock tire size. I've never checked it by mile markers and holding it on 60 MPH or any other method. Just the GPS. But isn't the GPs pretty darn accurate?
