   The evaporator is leaking and apparently is a known issue from ford and they didn't report this. The evaporator core is leaking and it blows hot air for a good amount. It draws a lot of power form the system and drops the rpm below idling. Forcing me to rev a cold engine so that it does not stall out.

   A plastic clip ("Brake Pedal Bumper") broke and fell out of place, causing the brake pedal to no longer reach the brake light switch.

This also caused the engine and transmission to go into "limp mode", the engine no longer revving over 2,000 RPM, the transmission not shifting, and hill-start assist and traction control no longer working, making the car unsafe to drive. The brake lights will…

    The little rubber pad that it attached to the brake pedal disintegrated. Without that pad the vehicle goes into limp mode and won’t drive over 40. Don’t know why the brake switch is connected to other electronics in the vehicle that would make it go into limp mode. Very unsafe while driving on the highway.
