Tire Blowout problems of the 2007 Toyota Camry

I was traveling on the highway yesterday when my left front tire blew out(or what I thought was a blow out). I was in heavy traffic and was, by the grace of god, able to keep the car in control. When I was able to pull over, I found that my tread had completely separated from the tire and when it peeled away , it took part of my bumper away. I get regular maintenance on this car. I just purchased it a year ago. There was no indication of a problem, no noise, no "light" nothing. Just boom.

My 2007 Toyota with only 14,000 miles on it is already out of alignment and wearing the inside of the tires. I thought that I had a defective tire because of the thumping noise and was told by the dealer that it was because I did not rotate the tires. I had rotated the tires 1 time during the 14,000 miles and the rear tire was "cupping" the same as the front tire. This proved that the alignment was bad probably from the factory. I talked with the salesman at the dealer and he said that I should probably have an alignment done every 6 months. I have never had to get an alignment done on a new car until I bought new tires. They did not offer me anything even though the car is still under warranty. I feel that this is a safety issue due to the fact that if I were someone who was not aware of what was going on with my tires due to improper alignment from the factory and the tire would wear on the inside (as mine are) where it is not noticeable there could be blowout of the tire resulting in a serious accident and even death. I would like to see Toyota issue a recall on all 2007 Camrys for front end alignment or else reimbursement for those who have had to get their vehicle aligned (as I am about to) due to the fact the dealers are unwilling to warrant this work. I have read consumer web sights and there are a lot of these cars with the same problem. Please, in the interest of safety, make Toyota accountable for this failure of design.
