The driver side window appears to be off track, when rolled down I can move it back and forth by pushing it. When you roll it up you have to first push it back into place or it makes a cracking noise. The passenger side window gets stuck and sometimes doesn't roll down. On Mazda forums many, many people are complaining about the same thing.
