Own a 2003–2005 Aviator? Chances are your lift-gate is cracked. Complaints about cracked rear panels in that generation of Ford SUV’s including the Aviator, Ford Explorer, and Mercury Mountaineer is one of the most commonly issues reported on CarComplaints.com.
A Manufacturing Problem?
The crack is caused by the buildup of water and air behind the window panel over time. It’s more than cosmetic as some owners have said as the crack grows it allows water to enter the vehicle and soak the trunk floor. There are even some reports of sensors getting fried from all the moisture. The rear panel lawsuit wants Ford to cover the cost of repairs — which can be hundreds of dollars — saying the company knew about the problem during manufacturing, but kept pumping out the panels anyway.

Ford redesigned their SUVs in 2002 and started using a polymer called ABS (acrylonitrile butadiene styrene) for their rear panels. ABS is supposed to be resistant to heat and tough impacts, which makes sense and points to a possible manufacturing defect causing the cracking.
The automaker switched to a blend of plastics known as Xenoy in 2003 which, interestingly enough, has experienced cracking problems in other applications.

Not Just Cosmetic
The cracks allow moisture to build up and corrode components that were supposed to be protected by the panels. Eventually, the cracks will allow the rear panel to break off while driving.
