2007 Honda Accord V6 6-speed stick, love it. When new, navigation system had a problem; dealer swapped out computer for a new one and it's mostly great. Except: occasionally trip computer zeroes out current mileage and MPG calculation, and loses history of previous tankful of gas (it's supposed to only zero when I buy gas, and then it should move current statistics to history). Dealer -- of course -- says "Duh, haven't seen that before". Minor but annoying problem, since I track the car's numbers.

 

Well, I'd bring it back to the dealer since their techs' hands were already into it...

 

I have, several times, for other matters, but mentioning this. No trouble found. So simply telling them about it AGAIN didn't seem worthwhile. On Car Talk forum someone suggested tell them to check voltage supply for ECU memory since it may have intermittent connection, so I will.
