So this is something i should have paid attention to 10k miles ago. Driving down the highway today had cruise set on 70 and i look over at the car next to me which is a new accord. the speed readout shows 65 and we are side by side. So i find another vehicle with a digital read out and theirs is 64. So a few miles up a lexus passes me and theirs is set on 70 and just goes right by. So apparently my leaf is off by 7-8%, so i assume my mileage is off as well which concerns me as this is a lease and i would be paying for miles that are not being used. Would the dealer be able to fix this issue or would they simply say all the other cars are off?
