Engine Stall problems of the 2011 Volkswagen Jetta

I purchased the Jetta used from carmax in nashville, TN in 2014. It began having safety issues on March 2014. Randomly, my car will just stop while driving down the road, or after accelerating from a stopped position when moving on from a stop sign or stop light. I can be driving anywhere from 15 mph to 50 mph, and all systems shut down. The battery light goes on, the steering locks, and the brakes lock. I always panic, put the car in neutral and have luckily managed to veer off to the side of a road and stop, shut the car off, and turn it back on again. Eurofix tried to manage the problem by replacing the crank sensor and cam shaft. But he problem came back, much worse. The second problem is now I cannot unlock my drivers side door with my magnetic key or by sticking the actual key in the lock. I see that another recall has been announced for the 2011 Jetta that is not pulling up via my VIN number, but I believe it might be my car's issue: online, ate that in March 29, 2011 (published by NHTSA) in which an issue with "an electrical wiring and fuse layout where the converter box is protected by the same fuse used by the signal horn and the anti-they alarm system. Should that fuse be blown,, the converter will be disconnected from the power supply which in turn will shut off applications such as the engine management system, lighting system, and wipers". . . . . . "should this happen while the vehicle is being driven, the engine could stall or the headlights or wipers could turn off unexpectedly, potentially leading to a crash without warning. " please help me!!!!!!! what do I do. What will remedy this situation so I don't get killed or kill others. I't gonna happen. . . . Then my family will file a lawsuit. I need guidance and for this car to be fixed/traded out.
