My wife is a realtor and often has to travel to remote locations to show clients properties for sale. Because this problem has happened on multiple occasions, I don't feel that she's safe. It first happened when I was waiting for her to come out of a store and I was listening to a sports radio channel. The QX80 died after only 10 minutes of listening to the radio. We immediately took the vehicle to the dealer and had the battery checked. The mechanic said that there were so many electronic components to the vehicle, that it would automatically drain the battery.

I find this an unacceptable answer. A vehicle with so many features should be designed to handle something so simple.
