Today it rained all day in Michigan and when I got home I notice both headlights had condensation in them. I have never seen this on other cars with sealed housings.

So are they defective or is this normal?

 

In my opinion that is not normal. I have driven through to severe rain storms with this car (not by choice), and have had no issues as you have. That is moisture. Take it in and bring your pictures!

 

I had the same thing happen to my 2 day old brand new Turbo. And I showed the dealer they said it was normal. The back of the casing for the light is vented. They were right it went away after I turned the light on.

 

Just went to the dealer again today for my screwed up PCM - yes..this will be 4 PCM's in a week and I'm getting cranky.

They also said the headlights were vented and this was normal. well at least they're not broken.

 

On the headlights, that is good to know. Does it happen when you wash it?

GL on the PCM, just not right!

 

I have only noticed it after driving in rain and about 50 degrees out. I didn't notice it after going through the car wash.

 

I had that happen to my 07 Lexus GS. Dealer replaced headlamp unit.
