At 8 months and 3400 miles (aprox) car would fail to start at random. Lights would flicker, engine check light would come on and doors would not work. Battery was charged but that only helped for a few days. Dealer replaced battery under warranty but problem reoccurred after about a week. Car stayed at dealer a week and was told it was another defective battery. Forward 5 months, car failed to start again. Road side asst jumper started. Car was taken to dealer and is still there as they are unable to to diagnose problem.
