The rear cross member / AKA (Rear Subframe) P/N GEG1-28-80X has completely rusted out. The car is no longer safe to drive per a Pennsylvania State inspection. If driven parts of the rear suspension will drop off the car creating a hazard to other motorists and the driver of the car can lose control / mobility causing a traffic accident. Picture the entire rear suspension suddenly collapsing, that is what is going to happen. The Front subframe was subject to a recall. That recall should have included the rear as it is the same material just a few feet away, subject to the same rusting issues. These subframes were not property designed to prevent rust or even withstand a little moisture, as my car has been very well maintained. When I read the online forms this is a flaw in ALL 2009- 2013 Mazda 6's and the sister car the Ford Fusion and Mercury Milan. I have opened a case with Mazda USA case #[XXX]. They are going to inspect to confirm my mechanic diagnosis. However they are currently under no obligation to repair and replace the rusted parts but they should be as this should have been replaced when the front subframe recall was performed.

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? There’s only 2 things that are rusted on my car, period…the front & rear crossmembers!

I'm filing a complaint as to substandard steel being used in the rear crossmember/rear subframe. Extensive corrosion has been confirmed upon a state inspection, which requires replacement at my personal cost. The front engine cradle was replaced in 2019, per a recall notice for the same extensive corrosion problem. A safety issue that needs to be addressed by Mazda.

The contact's daughter owns a 2011 Mazda Mazda6. The contact stated that while her daughter was driving at an undisclosed speed, the steering wheel inadvertently moved to the left at a 30–35-degree angle. Additionally, the rear end of the vehicle swayed while coming to a stop. The vehicle was taken to an independent mechanic, who determined that the crossmember was severely corroded and the front driver's side crossmember had cracked. The vehicle was then towed to the dealer, where it was diagnosed that the front sub frame, sub frame link, sway bar, sub frame nuts, and bolts needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The contact related the failure to NHTSA Campaign Number: 19V323000 (Structure, Suspension); however, the VIN was not included in the recall. The failure mileage was approximately 89,000.

Rear subframe rusted and cracked in half when my daughter was on a major highway!

My 2011 Mazda 6 rear suspension broke while my wife was driving our car on the highway. It could have killed my wife and son. The frame is rusted so bad that the lower control arm broke away from the frame, the rear wheel is barely hanging on it by one bolt on the front control arm. It is very much a safety issue and Mazda needs to take charge of the problem before someone dies in their vehicle. Our car has 106215 miles on it and we still owe alot of money on this thing.
