I had my passenger side headlight replaced because of this problem but dealership would not replace the driver side. They said that the light had to be collecting water in the bottom of light or GM would not replace or cover the cost of light. The passenger side did puddle ,collect water in the bottom and started to freeze in the winter. To this day my driver side stills fogs and condensation builds up but not as bad as the passenger side did before replacement. Over time the driver side will clear depending on the weather. Since they replaced the passenger side, the new headlight does not fog at all. Now you can see the differents from the new and old light, even when the driver side is not fogged with condensation. It looks as you see it, one looking old and the other looking new. I love my Malibu but GM really ticked me off, knowing that there is a current problem with these lights and refuse to replace both. So if your dealership replaces the lights and they are not collecting water on the bottom, the cost falls on that dealership not GM/Warranty. So I guess it's really depends on if the dealership wants to take that chance of absorbing the cost.
