Engine light and no acceleration on highway on 2008 Ford Escape

On purchase - fan/blower in AC/Heating system made loud noise when dial turned up. Dealership replaced the fan blade, stated sometimes they get "stuck". Problem occurring again + engine light on and no acceleration past 45mph.

dealer needs to re check there work. sounds like the motor is defective.
they also need to pull the code for the light and determine the failure. it sounds like a cat converter issue.
