Brakes Failed problems of the 2011 Nissan Leaf

My Nissan Leaf has never been in an accident of any sort, and has never even been driven over a curb. It is less than 18 months, and less than 15,000 miles. Front the day I got it, I felt that at times when I pressed the brakes on it, that they would slip, or not grab for a 1/2 second, but thought this might have been me. The car failed completely 10 days ago, and will not start, telling me that my foot was not on the brake! (a condition for starting). Combined with the fact that it cannot see the brakes being heavily depressed (for starting) and its computer controlled brakes slipping for 1/2 second, it makes me think that the computer has some reason for not seeing the brakes working. The Nissan dealership, and Nissan USA have been unable to figure out what the problem is, and after 10 days Nissan USA has not gotten any closer to a resolution. Is this a computer/braking defect? is it common? it certainly affects the safety of those riding in a car, as brake failure is certainly as important as an accelerator sticking. Has a recall been ordered for this, and how many cars are involved in it?.
