I had condensation in one of my headlights, and the driving light went out, you cannot change the bulb in these headlights only the ballast, you do have to take the whole bumper off to get to the ballast. If the ballast doesn't get it to work, you will need to buy a complete new headlight $$$$. Or find a used one somewhere.

 

I think there's a TSB on this, your dealer should replace it free of charge. Anyone wanna chime in?

 

TSB yes...condensation due to crack in housing.
Covered under the basic warranty. If out of warranty, argue that it's known issue and you're only just out of warranty...they should cover all if not most.

 

Do you have LED or HID headlamp

​​​​​If you have LED, it's not serviceable. Get them replaced under warranty like mentioned above with TSB issued

 

Good stuff to know ahead of time.
