Car Will Not Start problems of the 2010 Ford Fusion Hybrid

The car stalls at varied speeds which is a huge safety issue. I owned a 2010 Ford fusion previously with my company fleet vehicle program, and had the same problem. I brought the car to the dealership and it was fixed without question. At that time I was unaware of this being part of a bigger problem. In the fall of 2011, I purchased a different 2010 Ford fusion from our fleet as it was being turned in, and this is the vehicle that I am discussing in this forum. It only has 30000 miles on it, but is 6 months out of the 36 month bumper to bumper warranty. The car stalled once, a month ago, and the problem seemed to rectify itself. Then yesterday, 6/19/2013, it stalled 6 times. My 17 year old daughter drives the car and was stuck in the middle of a very busy intersection. For almost one minute, the car would not restart, but finally did, and she was able to get out of the intersection. As I read the forums, it is obvious to me that this is a nationwide problem, looking back, I've had 2 cars with the identical problem. The service men at the dealership know that the problem is specific to the throttlebody, which is defective, and there is over a week backlog on the parts as more and more cars are having the same issue. This is a dangerous problem, to lose power to a vehicle in motion and Ford is aware of this issue, yet they are taking no steps in addressing the issue. It is going to cost me $600 to have the part replaced, as it is outside the 3 year warrant, yet Ford knows that this was a model wide issue with a defective car part. I am disappointed and angry that a glaring problem such as this is not being addressed due to Ford attempting to let the problem hopefully just fade away and not be taken to task over this issue. I pray that the NHTSA will step in, right a wrong, and in the process prevent a tragic accident before it becomes a reality.
