The X3 showed a warning that battery was discharging. Took it to dealer , They said because I did not drive it enough , it did not charge up the battery properly and is not covered under warranty . It is 2 years 3 months old with under 14,000 miles on it. I am retired and don't need to drive it a lot. I think it's crazy that I either have to keep a trickle charger on it or spend extra money on fuel to drive it more than I need to. I think they should cover it.
