About February 2004, two months after I bought my car the windshield seal poped up from the bottom of drivers side. Dealership placed a new windshield and sealed it back. A month later the seal came off again on the same side. I went back, this time they just resealed it. Then, my sunroof began to leak,through the ceiling lights, I went back again, they looked it up saying its nothing-vents needs to be cleared up. After that procedure my windshield began to leak!now after each time it rains, inside of my car accumulates water-my radio/cd buttons failed to work anymore, plus the interior starts to get ruined by water spots. Its a problem to me , not only because I'm leasing the car, but 'cause it takes away my millage going back and forth to fix it, plus my time. Ps. I have a slight problem, at the time of purchising the car, dealership told me it was leased to one owner (year before me), but I went to carfax. Com and found out it was not only leased to two other people, but it was used as a rental car at the very beginning. If I had known those facts as I was buying the car, I would have never signed papers for it. When I got back to the dealers with this information, they told me it wasnt a big deal and that nothing could be done about it. I personaly do not like to fix problems on this "new" car of mine, after other people might have been responsible for them. Thank you for your time, I hope to hear back from you soon.
