The difference between the odometer and real speed is 7 to 10 km. Higher speed, higher difference.I used GPS and road check devices to verify the discrepancy. Mentioned it one time to my dealer but the problem had not fixed.

My speedometer is about 8-9% off. Aside from being able to tell from 20+ years of driving, my Garmin GPS says 92kph when the speedometer says 100kph. A salesman at Mitsubishi suggested it may be related to the tire size, as the Outlander will take 16", 17" or 18" tires. The service department told me that since I wasn't using a Mitsubishi testing device, they did not care what I thought and suggested "customer trust Mitsubishi installed speedometer".

When riding the truck @ 100 Km/H then I noticed that everyone were passing me on the highway. I installed my Garmin GPS and I was in fact running 92 Km/H. On another occasion my wife was following me with my second car, she noticed that I was running slow, again 8 - 10 bellow limit. I asked the dealership to reprogram the cluster but they said that we need to make complaints like this one to have it fixed.
