November 16, 2023, Porsche was informed about optically impaired windows in the field.
First analysis revealed that residues of salt bath in the primer area may have prevented proper adhesion to the glass. Inadequate cleaning after chemical treatment in potassium salt bath was identified as the possible cause. Further field analysis did not reveal any accidents or injuries, but 15 warranty claims concerning cloudy surfaces or other optical deficiencies. A lack of adhesion of the windshield to the body was never observed by a customer. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 24V-155
