I have been having battery issues for 2 years. Purchase 2014 qx80 brand new. I am going to try the reprogramming and hope it works.My brother wants to purchase the vehicle which I refuse to sell him if there are these known issues that cannot be resolved. Going for vehicle service tomorrowCheck the service bulletin linked above. The Nissan dealership service department here reprogrammed the ECM and I haven’t had any problems since. Been about six weeks.
