general problems of the 2005 Mercury Mountaineer

Back rear windshield keeps exploding on its own I’m not the only person to complain about this.

The plastic that hold the visor arm on place crumbles. Both sides were affected. The outer shield plates seem ok it's only the piece that I can only guess, 'stabalizes' the visor when you move it from front to side of the car. It looks like they're about $30-$80 each to replace. This is a 3rd hand vehicle however the mileage is fairly low for this year at 127,408. These are not plastic pieces that are in the sun a lot, they aren't at all but crumble like plastic can because of sun exposure. There is glue in the photo that I put on as a temporary fix but it peels off easily.
