Problems with 2008 Audi A4 STRUCTURE

I recently purchased a 2008 audi a4 3.2l cabriolet. about 4 weeks ago, while driving, i noticed it sounded like one of my windows was open, as i could hear other vehicles driving by louder than normal. i tried rolling up the windows several times with no change in sound. all windows were up. once i arrived at home, i did a walk around inspection of my car, and saw that my rear window was detached from the convertible top. there was no damage to the window or convertible top, just the glue/sealant had worn off (after only 2 years!). there was very little adhesive left on the top-center of the window. it was hanging on by about a 2" strip of adhesive. this trip home was 26 miles on the highway at speeds of >55mph. had there been a little more wind or the need for evasive maneuvers, this window could have easily detached fully, and hit other vehicles. after doing research online, this is a common problem for this vehicle. the only audi dealership on island couldn't get me in for >2 weeks. due to not wanting rain damage, or the window to cause a mvc, i purchased some silicone adhesive/sealant and put it back on myself. i can no longer put my top down without the window separating again. *tr

I accidentally drove over the rumble strip on the side of the highway. the right rear tire blew and the car flipped over six times and changed direction. every side air bag inflated excepted for my side, the driver's side air bag. the front air bag did not deploy either. my a4 was completely destroyed except for where i was sitting. when the first responders came they did not expect for me to be alive and the accident was classified as a level 2 trauma. i hit my head on the driver's side window and suffered a major concussion with a hematoma. i also had major facial lacerations, a broken nose, broken ribs, and a severe bone bruise on my knee. audi sent an inspector to the car after the accident and his conclusion was there was not enough impact on the side of the car even though the car flipped six times at highway speeds to deploy my side air bag. every other side curtain airbag deployed. the only other passengers in the car were my two labradors. no other adults were in the car. the two labradors each weighed less than 65 pounds and i weigh 135 pounds. audi has given me a free maintenance package for my next audi. thank you for looking into this matter. a dvd of pictures was made of the car along with a report of the condition of the car after the accident. *js

Driving on interstate, light traffic, 65mph, 5pm, good but wet conditions. sun roof exploded! very very loud. baseball sized hole in exact middle of sun roof with glass pushed outward (bowl shaped). no impact with rocks or anything else near by. no car in front but a car in next lane. dealer had not heard of such a problem. cost was about $800 for replacement which warranty apparently did not cover according to dealer. *tr
