'99 power window problems

Back in 2001 my passenger window died, bad regulator. It was still under warranty and no problem. July 2005, rear passenger window dies, 1 week later rear driver window dies. $678 to fix through dealer. August 2005 Driver window is now dead. 3 regulators/motors die within a month of each other, that just seems weird to me.

Are other owners experiencing the same thing? Every one of my windows went bad(regulator/motor). Is this a common thing with power windows? This was my first new vehicle and only one with power windows.

Not sure how common this is on the Elantra. I have heard of several problems like this on the '03 Tiburon, but that was the first year of the new style and a few problems were discovered. I have a '99 Elantra, but it has manual windows, so I can't compare there.
