I know this has been discussed before, but I would like to post this anyway. I have had my TSX for about 7 months now. I just took it in for a 6th month service. After the service I noticed that there was moisture inside the Headlight on the drivers's side only. The moisture was mostly concentrated by the High beam area, but sometimes got to the low beam area.

So I called the dealer. They knew about this problem and had to order a new part. But because they don't keep these things in stock, they had to order it and it takes 7 to 10 days to arrive.

So please if you find moisture inside the Headlight, please call your dealter to have it replaced under warrenty.

 

I had the same problem. The condensation caused the low beam on the driver side to short out in mine. It sucked pretty bad driving a $30,000 brand new car with one working headlight for a week. It was fixed under warranty though

 

My driver's side low beam just went out yesterday, moisture is inside the headlight assembly so I assume it shorted out. Calling dealer today.

 

Sorry to hear.
