Car was about two weeks old when I went through a touchless car wash. Got warning light as soon as I got out of the wash. Checked the tail lights and it was completely non-functional - no brake lights, no directional lights - nothing. Saw water inside of the tail light housing and obvious that the thing wasn't sealed properly. Went back to dealer and service guy said it might have been a bulb that's a bit loose. Then I told him that they are LED lights - he then backed off and actually looked at the water residue. Entire tail light assembly needed to be ordered from Mexico. Two weeks later it arrived and the fix was completed in about an hour.
