2003 Ford Escape drivetrain & axles problems

Cable on vehicle accelerator pedal broke and car accelerator unchecked. I needed to"stand" hard on my brakes to get any contol of the speed. I was on the freeway and transitioning to another freeway when this occurred. The only way I could stop the car was to turn off the motor once I got near the shoulder and use the brakes and the emergency brakes to come to a stop.

I purchased a 2003 ford escape with 24,000 miles on it. I should have known better, as vehicle stalled when I test drove it, but was assured the PCM just needed to be reflashed. 3 days after purchasing the car it stalled out on me when turning a corner, foot not on the accelerator. Was only able to get the car restarted after really revving engine hard. Took it back, assured me it was my "anti-theft device" two days after getting vehicle back, stalled yet again when pulling into my driveway.
