This vehicle has a feature where the door mirrors angle down when the car goes into reverse, and then comes back to normal viewing position when you change to any other gear (e.g. park, drive). intermittently, one mirror (driver or passenger) does not come back up. the driver will not likely notice the mirror not returning to it normal viewing position until he uses the mirror again, like when he changes lanes. i have had this happened almost a dozen times to me. i have almost side swiped other drivers on three occasions. i have been to the dealership nine times so far, but they have not fixed it. it is hard to diagnose because it doesn't happen often. many other hyundai genesis owners have seen this issue. http://www.genesisowners.com/hyundai-genesis-forum/showthread.php?t=10483. *tr
