2009 MAZDA MAZDA6 Complaints

Purchased the 2009 mazda6 for our daughter. Brought it to our mechanic for an electrical issue. We were told that the rear subframe was completely rusted and that the vehicle was unsafe to drive.

the front crossmember rusted out and broke while driving down the road (per owner), all bolts needed replaced along with the rear engine torque strut mount. Confirmed and replaced by an independent shop 01/20/2024. upon inspection the rear crossmember, lower control arms, bolts, and other parts are all rusted and ready to break at anytime. front crossmember is at the shop for inspection. Car can easily be at shop on a lift for inspection. No warnings.

Both my back and front chassis are completely rusted through and it’s a complete screwed car. Looking online there is a recall on something like this but not for my model? All I see online is people talking about how they had to scrap their cars because of this issue. The salt and snow has ruined this car and so many people have complained to no avail.

The contact owns a 2009 Mazda Mazda6. The contact stated the vehicle was taken to an independent mechanic for the replacement of the headlights, and the mechanic discovered that the rear suspension was rusted and corroded while the vehicle was on the lift. Additionally, the passenger’s side rear spring was detached. The mechanic advised the contact that the vehicle was unsafe to drive. The rear suspension needed to be replaced; however, the vehicle was not repaired. The manufacturer was notified of the failure and stated that the vehicle was not included in a rear suspension recall for corrosion and a case was not opened with the manufacturer. The approximate failure mileage was 138,000.

I brought my 2009 Mazda 6 to the dealership to inspect the suspension after the car began pulling to the right when braking. I was informed the front and rear subframes have failed on this car due to corrosion—even though the front subframe was serviced previously for the recall campaign with the addition of a support bracket. The front subframe will be replaced by Mazda due to the failed recall repair. However, Mazda will not cover the rear subframe at this time because it has not been recalled. The dealership recommends I do not drive the car until the rear subframe is replaced. However, the dealership quoted over $5,000 to replace it due to the high price of the subframe. There is a significant risk the lower control arms can separate from the vehicle due to corrosion, resulting in loss of vehicle control.

The REAR subframe has rusted out pretty much completely, but the total failure of the right rear spring mount has allowed the spring to punch through the frame, being stopped only by the top plate which has now turned sideways and is lodged between the spring and the floor pan. I understand this is a common problem with this and a few other model years, and has not been addressed by Mazda. I am hoping to help change this.

On October 13, almost lost control of my vehicle while driving at normal speeds in good weather. The car tried to pull off the road with every bump I hit. Drove it to tire dealership as I thought there might be problem with tire or suspension. Mechanic there told me the front engine frame ($595 part, approx $1100 labor) was completely rusted & he didn't know how I was able to drive it. I had it towed to my regular mechanic who said the frame has to be replace. Just in November 2022, I had to pay $290 (parts only) and approx $1100 labor for the rear frame to be replaced due to rust. I know this says the recall had been done but if so, the rear frame shouldn't need replacing again. I tried talking with Mazda for 30 minutes & they were no help. The web is filled with complaints about the front & rear subframes rusting out. It is extremely dangerous for Mazda to ignore this issue. I am attaching receipt from 2022 for the part & will have the receipt soon for the front engine subframe as soon as the mechanic is finished with the work.

Airbag light indicator continuously flashes. Air bags have been serviced previously under prior recalls.

* 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.
