sorry to hear about the auto wipers and the crack ....No, but you have my deepest sympathy. I've learned there are many systems tied to the GLA windshield depending on your options...auto-rain-sensor for the wipers, lane keeping assist are two for sure. My auto wipers have not worked since delivery, and almost 8 months later the local dealer is still trying to resolve that. This experience has terrified me...what if I had a cracked windshield? Not a simple event. Wish you well, please keep us posted on how this progresses.
