Frame Rust problems of the 2010 Mazda MAZDA6

My wife was driving on the interstate at 70 mph when all of the sudden the car veered to the right causing her to go into the right lane as she was in the left lane. Thankfully no one was beside her and she was able to keep the car under control. She stopped and called me as I was at work to explain what had happened. She was just a few miles away from the exit in which we live just off the interstate so she was able to limp the car home. Later that evening when I went to look at it I noticed immediately that the passenger tire was pointing outward a little bit. I jacked the car up looking to see if a tie rod or control arm had broke only to find that neither had broke. I looked at the frame and seen how badly it was rusted and noticed it actually had broken apart and was shifted. This area of the subframe is directly under the a/c unit which drips straight down onto the frame area that is rotted. Which is obviously the reason the the frame rusted and broke and shifted causing the tire to point outward. Called Mazda and they sent a tow truck to retrieve the car. Currently waiting on their inspection and a call from Mazda corp to see if they will be covering the repair. After reading everyone else's issues with this very same problem I'm assuming Mazda will tell me it's our problem. The car is only 8 years old and I've seen other's who's car are even newer and Mazda is telling everyone it's not defective. I strongly disagree with it not being a manufactured defect when clearing the water from the a/c dripping down is causing all these subframes to rust much faster than any other part of the frame. We'll see what they say but I'm not holding my breath. . . . Seems as though we the people need to band together in a class action against Mazda because this clearly is a problem for a lot of consumers. Pray no one ever gets killed do to loss of control when the frames do brk.
