general problems of the 2007 Mazda MAZDA6

Mazda 2007 Mazda 6 with severe corrosion to engine subframe posing a very serious safety concern if breaks while driving. Current Mazda 6 in question had less than 100k miles and was spotted by an oil change technician. I've asked a couple mechanics and was informed the car would be a possible death trap to myself or others if not fixed quickly. All parties are amazed at amount of corrosion, internet searches suggest this is a very common problem and already a recall in place for other year Mazda 6's.
