My question is since the a/c problem was a constant through these complaints and kept recurring, weren?t the final repairs, after April 2010 were due to pre-existing problems and that the warranty should have covered them, especially since this was a certified pre-owned purchase. By the way, this 2004 car had 2 previous owners before my 2007 purchase.
