Mustang Convertibles: Rear Window Glass Comes Loose

The adhesive holding the glass convertible window gives out and the window delaminates from the outer convertible shell. I used 3M VHB 2-sided adhesive tape (the same type that is used to hold glass panels to the outside of skyscrapers) to hold the window back in. It worked great, but long term effectiveness is still unknown.

Gas Pedal May Stick and Cause Unexpected Acceleration

On some Mustang Cobra models, the unique rear surface of the accelerator pedal may catch the cutout in the floor carpeting and not allow the engine to return to idle. This could cause longer stopping distances and/or unexpected, continued acceleration, which may lead to a crash. Dealers will install a shield over the cutout in the carpet behind the accelerator pedal. The recall began April 26, 2006. The Ford recall number is 06S43.
