Passenger side window of our 2004 Pontiac Vibe making popping noise when opening or closing. Sounds like it's off the track and snagging on something. We stopped using the window and contacted the Pontiac dealer. They want over $100 just to look at it. Newspaper article says other Vibe owners have experienced shattered windows which is what I fear is going to happen to ours. Pontiac should fix this design defect asap.

I had two events of failed front door windows on 2004 Pontiac Vibe one with broken glass all over drivers seat, received only minor cuts cleaning up as far as I can tell the windows came out of the track and with great force shattered. Into many pieces. The second time this happen it did not break only came off track. The local window company would not repair do to reputation of this happening. They told me to take it to a dealer, who repair it. Both times this happen when vehicle was stopped. I would hate to think what could have happened if the car was in motion. The 2nd time this happened and only came off track was recent and has not been repaired yet. I'll wait to see if I hear from you before its repaired.

When I briefly stopped on my way into work on 9/19/2007 in my 2004 Pontiac Vibe, I heard a loud noise in the drivers side door when I closed the window. There was no obvious damage and the window seemed to work okay. I then drove to work and entered our parking garage where I lowered the window to use a pass. When I raised the window, it stuck about 3 inches from the top. I decided to inspect it after I parked, but on my way up the parking ramp, the window exploded. Glass was blown throughout the interior. Fortunately, I didn't suffer any injuries although the loud noise and exploding glass was extremely frightening. My first thought was I had been shot at. I immediately put on the brakes and ducked down. Fortunately no one was immediately behind me. I parked and have made arrangements for repair. I read the complaints from customers in your NHTSA file. Several concern the same problem. A noise and then the window cracks, breaks or explodes. Why is there not an investigation?

I have been hearing a popping sound on the driver's side door window for a while, but I didn't know what it was. When I went to roll up the window it started sticking, then as it was going all the way up there was another popping sound and the window blew. I brought it to a place to be fixed. This popping sound also happend with the 2003 Vibe, but the window didn't break.
