Window Regulator Failed problems of the 1999 Buick Regal

The window regulator just failed yesterday on my 1999 Buick Regal- only 47k miles- we have replaced 3 other window regulators on pontiac grand am vehicles in the last 3 years. This is not a cheap repair- over $500 for each window! I see there are lots of people online complaining about the same thing. Buick and gm should be held accountable for faulty mechanisms and there should be some compensation for repeated failues such as these. I will not buy american made cars again with a history of failures like these.
