Sun roof drain clogs!!! no direction in manual for cleaning nor warning that it can happen. I found nearly three inches of water in the floor and water all over the interior fuse block. My concern is fire related. Corrosion can lead to high impedence connections and after water intrusion I have no idea how safe my electrical system is. This is the second or third incident and I finally found out what was causing the problem by doing research on the internet. Many others have experienced this problem and it appears that the design of the outlet nipple is the issue.
On Feb. 14, 2006, I was driving 65 mph on freeway, experienced loud explosion-type noise - after coming to reality and out of shock realized sunroof was blown out - and I was covered in glass - first reaction was to believe that I had been shot with gun or that something was thrown from overpass - after police investigation, photographs by dealership and dozens of eyewitnesses viewing the remaining out glass of the sunroof (that was still attached but shattered) was pointed in an upward position towards sky - not into vehicle as if it imploded from the interior to exterior - everyone determined that it had not been struck by anything but rather just blew out. This was very frightening and dangerous - I could have been injured by the glass or been involved in an accident from the incident. Everyone sent photos and spoke to Volkswagen of America - they do not care - and refuse to cover under warranty or even question me about incident even though - I have informed that I am fearful to even drive vehicle now - everyone that saw the car in person - is in awe and thinks this is weird - however, vw America the only party who did not see the vehicle in person - is still sticking by their answer that it was caused by something striking the car - there are other people with other types of cars on the internet with this same experience and they also know that they were not struck - I had a police report and photos with proof that the glass blew from the interior out - vw is showing negligence towards me and other drivers. This is the 10th odd incident that I have had with vw - and the second safety hazard - I am trying to get out of the lease because I am too scared to drive the car now. They need to be held responsible - and I am appalled that they were not even concerned with my safety or if I had injuries.
