The battery constantly goes dead in the car. i bought a new infinity battery in the car the same thing happened. you can reproduce this problem by sitting in the car listening to the radio for 30 minutes. i was sitting in the car listening radio and the car battery went dead and the car shut off. this is a huge issue, the qx56 is a 8 cylinder car. it does not charge very easily. i have to carry a battery charger in my car. i have been stranded several times in the last year. i have taken the car to infinity and they claim nothing is wrong with the car. since it is a big car the battery drain quickly.
