* Drivers side (worst) and passenger side rear lower control arm. Both are available for inspection upon request. * The drivers side rear lower control arm rusted through and cracked near the point where it connects to the rear subframe. The right lower control arm did not yet visibly crack (it's still on the vehicle), but it is also severely rusted. If driven and either completely separated, loss of control as well as flying debris on the road would have been nearly certain. * I cannot drive the car to a dealer or service center. The problem is visibly obvious and online owners forums anecdotally indicate the problem is widespread. * The component is available for inspection. I have shown my mechanic and intend to take to a dealer. Because there was no accident or injury, thankfully, I have no cause for engaging police or insurance. * There was no warning/indicator in the vehicle. The first symptom of trouble was severe wear on the inside of the left rear tire. The vehicle then had a four-wheel alignment and suspension components were noted to be tight and adjusted into spec at that point. Some weeks later, we heard disturbing noises from the rear as we went over even small bumps in the road. We noticed the suspicious sound during a local drive and drove gently and directly home, so cannot say how much the partial break may have affected control at that point. Upon inspection, the rusted & cracked steel of the driver's side control arm was readily visible. Other notes: The rear subframe itself shows significant flaking and rust in comparison to the rest of the vehicle's undercarriage, but at least there appears to be more substance left to the metal of the subframe. Photos & measurements available upon request.

The rear sub frame on this vehicle was not painted and/or coated to properly withstand the corrosion that is caused by the salt used to treat the roads in the winter. This can cause serious issues.

There was a recall on the front subframe due to rust. The rear subframe has the same safety issue but there is no recall for that and there should

The Rear Frame Suspension Cradle Subframe Crossmember has corroded and my mechanic at Jimmy's Tire and Auto in Granby Ct. says it is unsafe to drive. This corroded part is available for inspection while I wait for a used part to be delivered to complete the repair. No-one else has inspected the part. The condition was discovered when I had sent it in for general maintenance to replace the shocks and rear suspension linkages because there was noise in the rear when driving over bumps. The only warning I had was the odd noise when going over bumps in the road. I recall when buying the used vehicle many years ago that the dealer performed a recall on the front suspension #18V-631 and this shows closed.

Rear subframe corrosion/complete rot out, suspension complete rot out, and other components due to salt from the road and Mazda not correctly painting the components: 2009 Mazda 6I 2.5 Noticable drop in the back of the car. The tire wells are almost touching the rear tires. The rear tires are leaning inward, also putting inside ware on the new tires. The rear of the vehicle fishtails while driving. It takes bumps very hard. No suspension. When you hit a bump, the rest of the car is all over the road. Very dangerous driving conditions, as the fishtailing throws you into other lanes, possibly into other traffic. Took vehicle to Meinke on 3-15-23, was told and shown the damages to the rear suspension and rear subframe and other rear components. Vehicle is not safe to drive until fixed. Called Mazda dealer, was notified of recall on front subframe, but not the rear. Have appointment on 3-29-23 to drop off at Mazda dealer to get the front subframe serviced. My front subframe is not the issue, not that I know of yet anyways. My rear is the issue. Why was it not recalled with the front" Why are they allowed to risk the lives and safety of so many for not servicing the rear also" This needs to be recalled, and I am definitely going as far as I can into getting something done about this. I do not have the funds to pay out of pocket to get this fixed, or funds to go out and buy a new car. I am a mother of a toddler, and disabled. I'm hoping to get a class action lawsuit against Mazda for this, or at the VERY least, a recall to fix this issue also. I live in Indiana, we have some snowy winters, so salt is used on the roadways. I believe the car came from Ohio before I purchased it from Kentucky. I purchased the car on March 27, 2021. Have only had "normal" maintenance issues or water and tare before this, and actually love the vehicle! It has been a great vehicle, other then this issue.

The rear subframe of my car is severely corroded. Both dampers (not sure if I have that name right, the cylinder inside the rear suspension coil) have rusted off. The rear left lateral control arm has rusted off. It is higher in mileage so it might be expected, except, other owners have reported the same problem with way less miles. Also there was a recall for the front crossmember in salt states for the same issue but nothing issued for the rear. Driving on a rusted subframe could potentially cause major components of the rear end to rust and break off while driving causing an accident. If the front was poorly coated and had potential for severe premature corrosion, the back should also be addressed as well. Had there been something earlier many owners would not be facing the risk of a potential hazard.

We purchased this car last year for our teenage daughter. It is making a terrible banging noise in the rear. We took it to a mechanic who stated the entire rear subframe is completely corroded, the bolts are rusted, and all the components need to be replaced. This is thousands of dollars if we can even find the parts. As the car is unsafe to drive, I'm not letting my daughter use it until we can get it resolved. After looking at all the complaints, this is a well known problem that Mazda needs to address. There was a recall for the front subframe, but not the rear. Current mileage on the vehicle is only 70,000. The rear subframes and suspension links are severely rusted and deteriorating rapidly, making this car unsafe to drive unless most (or all) the components are replaced and the metal subframes rust treated. Mazda should be made to recall this vehicle and fix this problem before someone is severely injured or killed in an accident due to their negligence. I would be interested in entering into a class action lawsuit for this vehicle as well if someone pursues it.

The contact owns a 2009 Mazda Mazda6. The contact stated that while driving the vehicle at an undisclosed speed, there was an abnormal squealing sound coming from the front of the vehicle while turning, also while depressing the brake pedal. The vehicle was taken to an independent mechanic who discovered corrosion and a hole on the front passenger-€™s side suspension cross member. The vehicle was then towed to the local dealer who confirmed the diagnosis and informed the contact that the vehicle was previously repaired under NHTSA Campaign Number: 18V631000 (Suspension, Structure). The contact indicated that the vehicle had experienced the failure listed in the recall. The failure mileage was 85,600.

The entire rear subframe is completely corroded and rusted and caused the back right cross member to break. The entire rear subframe needs to be replaced including the control arms. This is unacceptable. Mazda had a recall for the front subframe, but not the rear which makes no sense as they were made with same materials. 2 separate mechanics have had the car in their possession and have both been unable to locate the parts in order to fix the problem. As a result, I am going to have to junk the car.

Original owner, purchased new, current mileage 35,700. The rear subframes and suspension links are severely rusted and deteriorating rapidly, making this car unsafe to drive unless most (or all) the components are replaced and the metal subframes rust treated. This is a well known problem among owners and the Mazda 6 has been recalled for rusted front subframes but not for the rear. The car spent 4 of its 13 years in upstate New York and the remainder in Alexandria VA and has shared parking space, car washes and normal maintenance with the family's 2000 BMW Z3, which has been driven 115,000 miles and shows no subframe/suspension rust damage. Mazda should be made to recall this and its other vehicles with this problem and either make the repairs or offer a substantial settlement for the inevitable scrappage of the car. I'm pursuing a class action lawsuit.

Component - Rear subframe/crossmember. Yes it is available for inspection. I was driving and suddenly heard a loud crack and the rear drivers side of my vehicle dropped to the ground. I was getting ready to pull into a parking lot so I was luckily driving slowly. If I were traveling at the normal speed limit, I could have wrecked and possibly caused injury to myself or others on the road. Upon inspection from the mechanic, the rear subframe is completely rusted out and broke as a result. After research, I found that the front subframe/crossmember was recalled in 2018 for rust issues. This car had the recalled repaired. But Mazda has no recall for the rear. There were no warnings that this was going to happen.

Hello, back a few years ago Mazda issued a recall for the front subframe of our Mazda 6 due to premature and extremely damaging rust that rendered the vehicle dangerous. We had this replaced and all was fine until not that long ago when we had to repair an exhaust leak and in the process realized how bad the rear subframe is rusted out as well... I've noticed the back wheels of our car have been cambered out by a few degrees for a few months and I'm pretty sure this is due to the rear suspension and rear subframe components collapsing on themselves due to the rust weakening the metal. I have some pictures which I will attach. Mazda currently does not have a recall for this part but we would, and many other Mazda owners out there on the forums would like a recall to be issued due to the extremely expensive nature of the subframe repair... I would really love to hear back from you all on this issue, I believe the car is fairly unsafe to drive at the moment... thanks in advance!

The car has only 31,000 original miles and I'm the original owner. The entire rear subframe and suspension assy is heavily rusted and suspension bushings are rotting.this is a common problem among owners in North eastern states and mid atlantic. Mazda recalled the front subframes but not the rear. This is a major safety defect and will result in the car having to be scrapped before it accumulates many more miles.

The contact owns a 2009 Mazda 6. the contact received a recall notice back in March of 2019 for NHTSA campaign number: 18V631000 (suspension, structure). The contact called garden city Mazda at 516-874-0385 and informed them that the parts to remedy the recall were unavailable. The contact was informed that when the parts arrived, the dealer would email her to have the vehicle serviced. The contact had yet to receive a notification to have the recall remedied. Also, while driving 40 mph, the vehicle began to jerk while depressing the accelerator pedal as well as when shifting gears. The contact stated the check engine warning indicator would illuminate intermittently both prior and after she experienced the failure. The contact took the vehicle to a local mechanic, but it was not diagnosed. The mechanic suspected that there had been an oil leak that affected the transmission. The manufacturer had not been notified of the failures. The vehicle was not repaired. The failure mileage was 94,000.

I brought my 2009 Mazda6 in for the recalled front cross member corrosion safety recall. After an inspection I was told it qualified for a replacement. I authorized the work and picked the car up a few days later. We did not receive the normal maintenance sheet. After driving the car the next few days the at (automatic transmission) light came on and transmission started to slip. We serviced the transmission fluid with 3 quarts and found damage and leak just above the cross member recall repair. We returned the car to the dealer and informed Mazda customer care. Walser Mazda of burnsville said the transmission line has rusted and repair costs would be around $400. I said the damage to the line was when the recall repair was done. The car was driven less than 250 miles since the repair and leaked out 3 quarts of fluid. I believe the sharp edge of the cross member damaged the transmission line when the recall repair was done. Damage should be the cost of the dealer. Document possible damage when this recall is preformed.
