-Crappy tires from factory
-Trans shifts hard in 1-2 or 2-1...requires PCM ref lash from Ford. Only really effects 07/08 models
-Paint bubbling on hood/rear hatch. Aluminum sucks. Covered under warranty though
Overall they are great vehicles. The 09+ 5.4 motor has different heads and plugs. No more sticking issues. I wouldn't hesitate to buy another one
