I recently had my software upgrade which I was told would improve the calculation of the miles counter. Unfortunately, there was a power fluctuation during my upgrade and the car froze. Nissan had to replace the vcm board. They reinstalled the upgrade afterward. Now, I'm getting about 25% less mileage than I was getting before the upgrade. The dealer is trying to figure out what's going on. The initial response was it must be your driving. I told them to check Carwings and see how highly rated I am, especially in trees and regen braking. I am waiting to hear back from Nissan.
Has anyone else had this problem? Is it possible that some of the battery cells were damaged during the power fluctuation?
