I have a severe rattle coming from my sunroof and sunroof reflector and the sunroof does not operate to the open position but will vent open but when it is in the closed position it rattles and shakes looks like it is going to fly off and I am very worried this is going to happen. I also seem to have a "car-pool" every time it rains because it leaks badly even when its being washed or in a light shower. There is alot of water damage on the headliner and water stains as well. And my vehicle seems to end wet inside after a rain shower or storm. The leak itself is not a huge issue but the rattle is. The sunroof is going to eventually fly off, this is inevitable ! I have taken it to be checked & no one can figure the cause. I do not want to even think about what will happen if the glass flies off & do not want to be the cause of someone dying or becoming badly injured. This is a very big safety issue, please recall this problem! I also have several other safety issues associated with this vehicle which my wife & I have filed under separate complaints on this site. I am not a typical complainer and usually just takes things in stride but this has become ridiculous! please do something!

We purchased our 2003 Hummer H2 in March 2008 and as we test drove the Hummer (fully loaded) we checked all the specs everything was working well and 1 or 2 days later we went to try and open the sunroof and it would not open, and we have also noticed that when it is raining heavy or light that our headliner has water stains and is wet right after it rains. We are also having a problem with the sunroof (fully closed) will shake & rattle and it feels like at any moment that it could completely fly off and cause a serious accident or even a fatal one due to the weight of the sunroof glass. I have done a lot of research and there are thousands of complaints on auto forums online, with this exact same issues that we are having. I think this should be considered a very serious issue but to the fact that if it flies off and it doesn't cause an accident, that it could go through the vehicle's windshield directly behind us. I think that this should be a top priority recall due to it being a manufacture faulty install and the other 2003 Hummer H2 owners complaints say that when they took their Hummer to the dealership, they were told it was a manufacture faulty install and were still charge large sums of money to fix a manufacture problem. I think that the Hummer/GM manufacture should be held liable, and pay for all costs & damage to the headliner & the faulty sunroof rattle. And we have to pay high prices for these vehicles alone, we do have a right to have these problems corrected & fixed, and we should not have to pay for any of it, since it was a manufacture problem. Thank you very much.

Any time it rains the vehicle fills up with water. The dealer has replaced the sun roof, the gasket in the drivers door, and the cargo hatch. The electric drivers seat moves up automatically when the vehicle is turned off causing the driver to be crushed against the dash board. The consumer feels that the hood is too heavy and that there is no support bar to hold it up. The vehicle has been to the dealer seven times since the consumer purchased it.
