speedometer accuracy

Finally found a free android gps app that does trip distance and everything else: GPS Essentials. I was using another one that did mph but no trip. Fully configurable page too. On to more calibrating!

If you have an iphone, well, you have my sympathy.

At least the speedo is better than the 6th gen Honda Civics. Never saw one less than 3 mph high. Mine was 4.5 mph high, ugh that was a lot of math when going through different speed limits.

 

actually i have a 7/100 toyota Bumper to bumper warranty, regardless, i have 32k on my truck and its 2 yrs old, and if my motor goes at 102k, it would actually been at 99k...and covered
but im not worried about the motor/trans, as much as the rear axle and the traction control stuff...but its more about not getting what you pay for...yeah im cheap

 

I think we used a travelled route that we measured with two vehicles or something to figure out if mileage was affected too. You're right, 3% is not bad, my 7-8% is worse, but I would bet a paycheck that the manufacturer would be fixing this issue pretty quickly if the speedometer was running 8% too slow! That way you could easily get another 8000miles free.
Also consider leases. They love to penalize people on excess mileage.
Our Liberty was a former daily rental. Although most places offer unlimited mileage with rental, some dont. And they will quickly charge you accordingly.
