Carrier/rack problems of the 2009 Nissan Versa

Trying to find out if recall on 2009 Nissan Versa. Noticed car engine seemed louder than usual. Mechanic found 'muffler neck' (bracket where pipe from engine goes into muffler) was rusted with a hole, had to get new muffler and gasket etc. , $389. 26 for parts/labor/tax. Mechanic showed me the muffler system that he removed. Rest of muffler/pipe system was not rusted, so I'm suspecting a design problem where water is somehow accumulating in that one area to rust just that spot, but requiring the whole system then be replaced. At about 81,000 miles and car is garaged, this does not seem like normal wear. I've read other complaints posted online also about the muffler system rotting out too soon, and many seem to be about the same mileage as mine. Either a design and/or parts quality issue, it seems.

A brand new car bought early January 2009. It has 60885 miles when incident occurred. The muffler fall down and broke at flange connection point. Went to Nissan dealer to check out and exam the problem. They indicate that a corrosion from inside the muffler pipe has occurred and caused this cracks, so it fall down. It was clear a poor manufacturing, or default in manufacturing this part was the reason to cause this incident. Dealer offered to replace it with a new part with cost up to $ 600, where it supposed to be free of charge. I would to claim Nissan us corp. Responsibility for this incident. They did not made early recall to replace this part where they knew the problem. It was clear that they wait to happen at any time to make more profits. This it looks like as a fraud. Suppose controversy, this muffler fall down on high speed road, it may be cause, and could be, a deadly accident. Therefore, I am asking you please to investigate this problem with all Nissan vehicles, and do what is necessary to protect us from such accident, and to provide us with a suitable compensation. Thank you.
