1. Driver door required more force to close. Later, I noticed the driver window would not raise more than half way. 2. The window regulator arm is bent, and the internal attachment point is broken. The window gets progressively worse over time, and the raised height becomes lower. 3. The dealer stated their must have been previous damage to the vehicle, and they were unable to resolve. Maaco said they were unable to resolve. More than a year later, took it back to the dealer, and the new service personnel were able to replace the regulator arm, and weld it to the door in March 2010. It's now June, and the window will no longer go past the half way point when attempting to close. Each time I've attempted to get a resolution, the dealer has insisted the internal door damage is a result of a previous accident (carfax is clear) or due to the previous owner replacing the door mounted audio speaker. Now, I read another complaint with very similar damage that makes me believe this is an inherent problem that the dealer should have fixed when the car was still under warranty.
