That would surprise me, as the odometer is used to determine if your warranty has expired or not, so there is a reason for regulation to protect the consumer from manufacturer having an odometer read with that much inaccuracy. When I got an new engine block from Jeep under warranty, yeah, that was not cheap and it was near the expiration of their warranty. My odometer was very close to matching my GPS for distance traveled on everything I have owned since I bought my first GPS in 2001.
Speedometer, it is common knowledge that manufacturers usually show a faster speed than actual, I am not questioning that instrument.
