I bought my Subaru Impreza new in February 2008. For the first 2 months or so I had to constantly clean a haze film off the glass (got so bad I needed to keep a rag with me for occasional cleaning while driving).
I understand that the plastic in modern cars is usually the culprit due to outgassing. But, here’s the weird part.
Warm weather arrived and it seemed to become less frequent, or got to be so intermittent as not noticed between normal cleanings.
Flash forward to this past December when a rock strikes the windshield, necessitating replacement…
New windshield, and again that oh so frequent hazing! And again, it’s winter and cold out.
I thought outgassing was worse in hot weather?
BUT, how can it be outgassing if the problem went away nearly 2 years, only to return thanks to a new windshield?
A few facts: I do not smoke. Ventilation always set to windshield and feet, which I believe automatically activates the a/c for defogging (not the reason I set it that way… cold feet and better ventilation is all).
