I'm reading the links provided and the articles keep saying "speedometer can be high, odometer is probably accurate." I have my doubts.

Depending on which vehicle I take to work, the mileage is either 16.4, 16.6, or 16.9 miles over the exact same route, with the fairly-new tires inflated to exactly the maximum pressure printed on the sidewall. If Google Maps can be believed, 16.4 miles is the correct distance.

You are absolutely right. The odometer does not go by the GPS speed (not all models are even equipped with GPS). The only way the odometer "knows" the distance is by the number of wheel revolutions and presumed diameter of the tires. Since over the life of the tires their diameter only goes one way, decreases, it would be logical for the manufacturer to program the speedometer with an average presumed diameter of the tire, not the largest (new) or even more. Since all reported descrepancies seem to go only one way closer to allowed +10 percent, it raises a huge suspicion. Think of millions of dollars people overpay for excess mileage in the end of their leases, think of premature warranties' expirations, think of overstated battery distance capacities/ EPA mileages, etc. Do we have a case of possible programming fraud similar to VW "clean" diesel scandal here?
