Drivetrain (motor, inverter, battery) should still be under the 8 year infinite mile warranty. Door handles are very common failures. The center 17" screen is known to get bubbles in it. The sunroof can also frequently have alignment issues, although they typical would have already been sorted by now. The tailgates frequently leaked, but that also would have been sorted by now, unless it was never an issue if the car came from a climate with no rain.
