2011 Ford Edge drivetrain & axles problems

I had been having on-going issues with engine surging, stalling and gear "skipping" since I first purchased the vehicle in december 2010, which I had reported to the dealership and about which I was in the midst of lemon law proceedings under ga lemon law. They are best described as similar in nature to those reported in the NHTSA investigation here: [link removed] at times, the engine would cut out at high speeds and I'd be stuck in "limp mode".

While traveling at approximately 30 miles per hour, the car suddenly stalled, although it would move at a very slow speed at a rough idle, maybe 1 mile per hour, no matter how hard the accelerator was depressed. Simultaneously, a yellow wrench warning light appeared. I pulled into a parking lot and let the engine run, it remained running rough at a very slow speed. I continued for about a minute, then shut the engine off. After restart, the car ran normally with no warning indicators.
