2013 Dodge Charger Window Louvers

Recently received this product, loved the look and it fit well. I followed all the instructions, cleaned the rear window, mounted it properly, even had pressure on the mounting hardware all night to ensure a good adhesion. The next day on the way to work, as soon as i hit 45 mph, the louvers broke away from the mounting strips like a pilot ejecting. Part of it broke as it hit the road, but I was able to recover it without any other major issues. I am going to attempt to re attach it with commercial products and hope it fairs better.
