I purchased my 2015 Buick in may of 2015. At about December of 2017 the drivers hid head light was breached and moisture crept in creating an inner fog and eventually a puddle of water. In the falloff 2018 the same thing happened on the passengers side. I've removed both head assemblies and tried to fix the problem with very little success. Now I am looking at replacing both lamp assemblies at a cost of $2200 not counting labor.
Drivers side headlight has condensation in it & stopped working. Vehicle hasn’t been involved in any accidents or incidents that would have caused this. Dealer advised of the problem while performing oil change.
