I have a 2014 QX80 (Love it!!) however, over the past several months I have been having issues with the battery. I have noticed when I try to start it, it lags a bit first then it starts. Had the battery changed 3 times - I have NEVER, since I purchased the vehicle new had any problems with it, only general maintenance. And all of a sudden dead batteries. So I googled and found this forum. Why do I have a battery issue all of a sudden after 6 years? I understand there is no official recall, but the dealership is aware of the problem. Winter is coming and I don't want to get stranded.
