I was so excited to pick up my '11 black cts-v coupe tonight... but the headlamps got fogged up with condensation because of the rain and humidity on the way home... :-( I've read previous posts about this problem from last year. Has anybody had the problem recently? I absolutely LOVE the car but this issue really got me annoyed. I'm calling the dealer first thing in the morning...

I have it in both of my headlamps as well. In fact, I just got my rear spoiler brake light replaced under warranty because it had condensation inside which had caused 3 of the LEDs to go out.

There were at least a couple replaced back in '09, but GM has since quit replacing them under warranty. One of mine does it a tad also, and only upon occasion. However, only happening occasionally is probably because I don't take the car out much in wet weather.

Had it in one of my headlights. The dealer enlarged the vent hole and that fixed the problem.

If they remove them to clear/enlarge the drain hole, swishing rubbing alcohol inside them before reassembly will also help any remaining moisture evaporate.

I would take it in to the dealer and have it documented at least. They may replace them because the car is so new. I have a 2011 V Coupe and mine doesn't do it at all. If my car did that, I would be taking it to the dealer while it is still fogged up so they can see the condition.

I would be more upset about the front license plate drilled into the front bumper than the condensation.

I have a 2009 CTS-V and have had no moisture problems or condensation in the headlights.

HAHAHA ... that's really funny. I completely agree with you. But I live in NY and I got pulled over and ticketed for tints and LACK of front license plate on my Audi... (I had to buy a $750 new grill for it with a license plate holder since I couldnt drill into the plastic grill). So I'm not taking a chance again.

I dont know about this condensation thing. It was raining really hard and it was humid last night when it happened. I took the car to the carwash and hosed water on the lamps for about 7 minutes and no condensation. But I'm still taking it to the dealer on Saturday.

ANDDDD.... it occured again tonight. No rain. Has to do with humidity level and dew point. I'm definitely taking the car back to the dealership. And to add insult to injury, the "service suspension system" message showed up on the screen (it reset after I re-started the car)... Jeez. Two days in this car...

Ran a V at Monticello today. All three cars had condensation in the headlights.

In Oregon you only take the car out in wet weather. :nono:

Maybe it's time I move to Long Beach...

Mine is a 2012 and had the drivers side replaced. The ordered the part just by me sending them a pic. I have a great dealer.

Mine does it too after it rains and its humid out. I thought about taking it to the dealer but I very rarely drive my V in the rain so I'll just deal with it. I did notice that sometimes when I wash the car it fogs up , not completely but enough to notice and then it goes away.

Mine will fog a little at the bottom of the lens when it is humid or infrequently after washing. The fogging burns off pretty quickly so it isn't concerning to me. I think a small amount of fogging is actually normal depending on weather conditions.

Would you know where is the vent hole is located?
Picture would be nice.
Thanks.
