Has anyone noticed their speedo being off? Checked with GPS and noticed it's off by about 4mph at 70. Car reads 70mph and gps reads 66mph, which means my actual mileage is off as well as my mpg readings. To make sure the GPS wasn't off, checked with my other cars they read more accurately. I don't plan on selling the car, but if I ever do, it means the car has less actual miles than it's reading decreasing the value of the car! Anyone ever get their speedo calibrated? Seriously want to consider doing it if possible.
 
I've gone and asked about it and was told there are no recalls on my car. Do we have a TSB or some other number that we can reference?
 
I think it was only for vehicles with ICC, but I'm not sure as I wasn't denied so didn't have to ask. I went from 4-5mph high reading to 2 mph high reading.

edit: nvm looked on Infinitihelp and it looks like they added all vehicles a little over a year ago. It does sound like you need to have the dealer confirm you are eligible though.

Got this taken care of yesterday. They adjusted the speedo reading, adjusted down odometer reading about 3000, replaced ICC module to work with new speedo reading. Speedo used to read 4-5mph too fast, now its down to about 1-2mph. Get it done if you haven't already! I just called the dealer and gave them my VIN to see if my car qualified, then made an appointment. They took care of everything, plus washed and vacuumed my car! Gotta love quality service!
