I was traveling at ~65mph on the freeway when the sunroof spontaneously exploded. It was louder than a gunshot—I nearly lost control of the vehicle. The explosion occurred in the outward direction. There was no evidence of impact of preexisting damage. Internet research suggests this is not an uncommon occurrence.
This issue has been happening since I got the car and is getting worse by the day. The car only has about 11,000 miles and I bought it when it had almost 10,000 miles. Something in the dashboard and behind the instrument panels (a/c controls and user screens) makes a lot of vibration noises/sounds as the car is slowly accelerated or as we drive over some uneven road. It seems like there is something loose. And this is getting worse by the day. When you pay a top price for a luxury car like Audi you expect that the care is built solid and not with cheap parts. . . It is very disappointing to see that a luxury car like Audi A6 will make these type of noises when the car is practically brand new.
