Three issues. all have occurred only twice or three times in two years. last time i took the car to dealer but they didn't do anything since no "codes" were stored in the system! 1. the infotainment display panel goes completely dark. radio stops and all other activity and control knobs become non-operational. just stopping and restarting the car does not fix the problem. but, both times, when i have restarted the car after 30-45 minutes (e.g., after shopping, or returning from airport), everything is back to normal. 2. sometimes (again infrequent) when using the navigation system, all colors go away, screen becomes darker, and everything displays in gray. but, when i change the display settings from auto to day, the color returns. all occurrences were during daytime driving. 3. again, sometimes, when listening to radio, the brightness on the display changes from evenly lit display of the dial, the two ends become darker - like gets dark and cloudy! *tr
