My 2019 QX80 continues to have some kind of battery drain. My son watched the factory DVD system for about 25 minutes, all of a sudden everything clicked off. A few minutes later I tried to start the car and it was dead. My dealer has already made an computer adjustment and replaced the battery once. I love Infiniti, as a matter of fact this is the 6th one that I have owned. I can’t believe that a $72,000.00 car will not start after playing the factory DVD system about 25 minutes. Something is not right. Is anyone else experiencing this??????
