We just bought our new to us 2010 xc70. So we decided to take a day trip to check it out. After a few miles I noticed we were being passed with too much regularity, and some pretty big trucks too. I finally realized after a few measured miles and then a check with the g.p.s. unit, we were traveling 4 mph less than the speed on the speedometer. My question is, Is this a fixable issue by computer adjustment or will the head have to be pulled and adjusted? I am planning to fuss enough about it as a "certified car" purchase that they will take care of it.
AND
I have been offered the extended warranty package for 2700$, covers everything, on a 2010 with 67000 mi on the clock, should I? After browsing through this forum I have noticed a large number of posts about transmission issues, it makes me wonder if maybe I should. The warranty will carry me another 48000 miles.
On the up side, it rides great, looks good, and wife is happy.
thanks for your input in advance.
