Adaptive Equipment problems of the 2009 Ford Escape

When driving the traction control light, brake light, and abs light came on. These light will not go out. Taking it to a mechanic, they tell me it is the abs module. The test cost $100. To replace the module will cost $1395. Should this not be a warranted item for safety? the shop told me that the abs and traction control will not work until the module is replaced.

P2111, throttle actuator control system stuck open, I had to drive to an auto zone to get this code while the car was in this condition. Otherwise these was no error code recorded. The engine run at an idle and will not accelerate when accelerator is depressed.

First occurance was while at idle the wheel wouldn't turn without extreme pressure. Now, 1/24/2013 the power assist goes in and out with no warning. The vehicle steering comes close to locking up but doesn't actually get there.
