Ah interesting, our 2011 CX-9 GT had had no issues with the lights etc, but we had a big thunderstorm/heavy rainfall last week - I just noticed this weekend that the drivers side headlight was all fogged up. It's never been fogged up before.
(car used to be in the Bay Area CA until last Summer, then we moved to Austin TX where it gets warm and humid)
This morning my wife told me that the low beam is not working on the car, she noticed it in her parking garage.
She has the car at work, but i will check it out this evening. I'm hoping that the ballast is ok - i do have a spare D2S HID bulb so I will try that first. I'm also going to leave the caps off the headlight for a day to let it dry out first.
