Query: short life

I bought it in end of April 2010 and used only by my mom who is petite and quite short to use over the range GE profile. In the past few months, I noticed that the leak (the wall on the right side of microwave was unsealed) and made loud noise. She did not complaint because we wave tight budget. But when I checked on-line for leak, it is very dangerous. So I have to buy a new one Panasonic NN-SN651W with double the price of this Sharp.
