To the person directly above.

Go study physics. The direction the glass falls does not necessarily dictate the direction of a foreign object.

When a diver dives into a pool of water, does water splash down, in the direction of the diver? Of course not. The displacement of the diver makes the water splash in the opposite direction.

Also, with tempered safety glass, the shape of the glass will control the direction of the glass bits when broken. Due to the inherent stresses in tempered safety glass, if the glass has any bow, it will explode in the direction of that bow.

And pressure differences will effect the glass direction. Underway, most cars have a positive cabin pressure, that rises with speed. if the glass breaks at any considerable speed, the glass may blow completely out of the car!

In any case, shame on VW for letting its quality & customer service go down the toilet.

In any case; Just get the moonroof replaced and drive the car for a while longer. I just finished reading a slew of comments on how awful the new Acura TL is, which I don't believe, but it does prove that even the great Honda motor company is not perfect. Stuff just happens with new cars sometimes. Let us know how the Jetta is doing when you actually get some miles on it. I am glad that you weren't hurt. Thanks all!

That dealership or Volkswagen in your city is wrong, and they should have paid for that repair. There must be some sort of organization in your country or state or city that would enforce rules for the car company to be accountable for faulty products.


1) Contact the main Volkswagen office of your state/province.

2) Contact the Consumer Affairs or Better Business Bureau for help

3) Example -- In Canada there is a government type agency that enforces regulations for faulty motor vehicles... I learned about this agency from a non-profit car-consumer-advocate organization carhelpcanada.com. It is in Canada, but the people there also have info about US organizations. A close inspection of the car, by an independent and approved examiner, should prove that the sunroof was faulty.

The same thing happened with my 01 Jetta. I was driving on the freeway and I heard a loud bang. I thought someone shot at me too! anywho, I opened the sunroof and sure enough it was cracked. It looked like stress cracks, I thought maybe it was from the heat. now the dealership want $734.00 just for the glass and I can't seem to find anywhere that sells it cheaper.

My sunroof just exploded an hour ago. I was driving at 25-30 mph on a smooth road. I thought some huge rock had fallen on it. I made a cautious U-turn to check out the scene, and there was no evidence of anything hitting my roof. The glass is bowed outward, and has three obvious fracture lines. It is shattered completely, but held together by the tinting, I think. When I stopped the car to look at the damage, the glass was still making a crackling sound.

I was driving on the highway yesterday in my 2003 Jetta when I heard a loud explosive sound... my sunroof blew out as well... it sounded like a gun shot and scared the heck out of me. I was on my cell phone with a friend and screamed... The slide for the sunroof was open. I had pieces of glass in the car, on me and in my hair. It was really frightening! I intend to call the dealership tomorrow and now know what to expect with everyone else's experiences... I also thought something fell on the glass, but now know it's possible for this to happen as a cause of a defect. I don't expect the dealer to be much of a help... thank goodness for insurance.

I was driving my VW Jetta 2004 today morning on a freeway and suddenly I heard a loud explosive noise and I realized that it is the sunroof that broke. I later checked if anything external hit on it and I did not see any external object in the inside subroof plastic tray. I called VW America and they said that they are not aware of this problem and they couldn't do anything about this.
