Mazda dealer was performing a couple of recalls. They found that the subframe was severely rusted. Said that it needed replaced before it failed. Said that engine could drop out or problems with steering if the subframe failed. 9 year old car with 100,000 miles and no other rust problems is unsafe to drive because of problem with the subframe. I contacted Mazda but have not heard back from them.
