I have a 2003 Ford Explorer and 2003 Mercury Mountaineer both with the same cracking problem. Dealer says there is no recall and other complaints that I have read indicate Ford will do nothing. Why did the design change back to glass hatchback only if this is not a design defect. I had (2) 2000 Ford Explorer and both had only the glass hatchback without the section of plastic below it. I now have a 2006 Explorer as a company vehicle with only the glass hatchback. So some time between 2000 and 2006 they change the design of this feature, realized it was a design flaw and returned to the original design and they feel they have no responsibility in this.
