Gross moldy odor emanating from the HVAC system caused by what appears to be a defect in the system which allows moisture to condense on the coils causing mold and bacteria to be dispersed throughout the vehicle. GM attempts to address this expansive issue by adding deodorant to the system and then hope consumers will go away.

I have a 2013 Cts Cadillac and the headlight assemblies fog up on the inside of the assembly. This happens when it rains or is wet dealer replaced the headlight assemblies but these are worst than the originals. Dealer now says this is normal thedealer refers to a bulletin 01-08-42-001J which states that lights might exhibit a fine mist or white fog on the inside of the lamp lens. The bulletin states that it requires 2 to 6 hours to clear the lamp and works better if vechicle in motion with headlights on..I've had the headlights on bright up to 2 hours and the assemblies still have some fog inside them. This decreases the effectiveness of the headlights and creates future electrical probelms because of the moisture within the headlight assembly. The fog shows up when you are driving the vechicle with the headlights on. Last date this happened was 1/15/2016. Car has a little more than 17000 miles on and was bought new. This had been a continuing problem that happens irregular.
