I seemed to have come across something odd with my CL and the odometer. A few weeks ago I drove from Charlotte to DC in a Pontiac Grand Am - the trip tracked in at 395 miles door to door. I just did the same trip the other day in my CL and noticed the mileage was adding up faster than the Grand Am. I zero'd out the secondary trip odometer at mile mark 103 on I-95. I exited at 163, so it should have been 60 miles. But the trip odometer was at 61.5 miles.

The primary trip odometer came in at 412 miles - 17 miles higher than with the grand-am for the same trip.

Sooo...I haven't modded the car at all at this point. Stock rims - with replacement Yokohamas - but the same overall diameter - they are slightly worn at this point but i cant imagine the odometer would be adding 2.5% extra mileage. Has anyone else seen this?

One more note - my friend has done the same trip from DC to Charlotte in his 328is and his trip comes in at 395 as well.

Anyway after this rambling setup - with 50K miles on the car, i figure about 1500 miles are phantom - do i even bring this up to the dealer? if the odometer is messed up i dont want to have that tagged onto the title - it will kill the already depressed resale value of the car- although i have no intention of ever selling it.

 

well i wouldnt worry about that.. maby its from ur driving style: lettin the tires loose a little or a few passes here and there.

 

maybe acura has recalibrated the auto cars to rack up miles faster to get out of the extended warrenty on the auto transmission debacle. hehe

 

Maybe the Grand Am's odometer is off...

Try checking both against a measured mile on the highway... (1 mile @ 60 mph should take 60 seconds on a stopwatch).... or borrow someones GPS to check...

 

Thanks for the replies, but the Grand Am as well as the BMW showed the same mileage. Odd.
