NHTSA Complaint #11710529 — 2012 MAZDA MAZDA6

The rear subframe and suspension parts are rusted so bad that the car is not safe to drive. Looked up recalls and found out the front subframe had a recall and was taken care of before I bought the car. Also found recall for my model of car that were registered in state that use salt on there roads which is one of the state i live in. Was told my Mazda corporation the only certain 2012 mazda vehicle's vehicle's were covered for rusting issues with the rear . If the front of the car is recalled and the same problem happens with the rear of the car shouldn't it be covered for something? I have an appointment coming up on the 21 of January which is ridiculous that I have to wait 3 weeks to have it looked at. . Thank you for your time. The only reason I found the problem with the car was a stick got stuck in the rusted out parts and when I took it out a bunch of rust fell on the ground.
