Carrier/rack problems of the 2002 Mercury Mountaineer

The car would have a warning display that a door was ajar and we would check all the doors and re-close them all and the warning would still appear. Then we would check the lift gate window on the back and re-close it and the display would go away, but the lift gate was closed the whole time before. It constantly does this and now the lift gate has a crack in it.

Hit the remote control button to open the rear hatch for the 2002 Mercury Mountaineer. The rear hatch opened only halfway automatically, as it is suppose to open further I pushed it up, without unusual force and the entire rear window shattered, and the encasement that held it hit me in the head rather hard. It is now without a window. This is the second window replacement. The first rear window was replaced in 2004 when, during a cold snap here in NY it spidered into a crack but did not shatter. When my husband took it to the dealer as it was still under warranty they argued at first, but then the phone started to ring and they decided it was an ongoing problem and design "flaw".
