After getting the recall information about the front crossmember rusting out due to corrosion, I decided to check the rear crossmember on my car. WOW, the rear crossmember is SO much worse than the front one and I've read hundreds of similar stories about the exact same thing happening to other Mazda 6 sedans around these model years (2009-2013). The rear crossmember on my car, which supports the entire rear suspension is completely rusted thru in several spots and the lower end links aren't even attached anymore because the brackets literally fell off and so now both back tires are leaning in at the top. It is very noticeable! Very unsafe to drive! I decided to park this car until a solution is reached with Mazda or the NHTSA on how to deal with this. I don't know why the front crossmember was recalled but not the rear? …
The rear cross member/subframe is completely rusted in two and the rear lower forward control arm is detached from cross member/subframe on both sides. There is currently an active recall for the front cross member due to accelerated corrosion from road salt but I'm not aware of any inclusion of the rear frame or suspension components tied in with this recall. It definitely needs added to it as this is VERY dangerous, possibly even more so than the front. Rest of the actual car body is fine, except for a little bit of surface rust. Please add this to the current corrosion recall! Car is registered in WV and is available for inspection anytime and I will be attaching pictures and I also have a video but it won't let me post it on here.
The front and back cross members underneath my Mazda6 have completely rusted out. There are numerous complaints about Mazda's "Safety Recall 2818I Expansion" not covering the back support member and also not considering Nebraska to be a Salt Belt state despite the state, and specifically Omaha using salt to treat their roads in the winter. On [redacted], my front cross member completely failed due to rust, causing my vehicle to lose control. I've taken my car to the mechanic and they confirmed the front and back cross members are completely rusted and need replacement costing $7,000.
I purchased a used vehicle in NH from a private seller "as is", repaired tires and brakes, passed MA state inspection and dropped the car off to address the recall, which I had researched via a VIN number search. The dealership informed me that the body had corroded beyond repair, and they cannot perform the required repair for the recall. While the dealership has been helpful, this looks like a major underlying manufacturing flaw for a vehicle at 115K built in 2011.
