In September 2017 while driving on a city street at approximately 30 mph there was a sudden and significant loss of steering control following a loud knock originating from the front end of the vehicle. Upon inspection the front crossmember/sub-frame was completely corroded to the point of breaking. The steering rack became totally separated from its mounts on the passenger side resulting in the steering loss. The failure occurred at 85,583 miles. Since the failure I have attempted to get this fixed. However, even after trying to get a replacement sub-frame from 4 different dealerships, I have been unable to get one for the last 7 months. They are back ordered and every time the date comes around, the date is pushed back further again, again, and again. I have reached out to Mazda's North american customer service (service request number 1-1245266941) and in the last month have gotten no more than we'll look into when a replacement will be available. In researching this problem, it is apparent that this is far from an isolated incident as many others with this model car report failures of this exact nature. The employees of the local Mazda parts departments are well aware of the complaints as well and have stated to me they are surprised that Mazda has not initiated a recall or tsb regarding this issue. These failures have the potential to create a significant risk of injury and it is my belief that Mazda is not treating this situation with the seriousness and promptness that it warrants. It is my understanding that this same part is was installed on not only the 2009 models, but all model years through 2013. If there is not corrective action taken, it is reasonable to expect this problem to persist for years to come as the other later models age.

Front sub frame is completely rusted out to the point of braking and immediately not safe to drive, rest of the undercarriage is completely clean of rust. Mazda Corp. Has denied claim to repair the damage under warranty. Please advise.

While driving at highway speed (55-65mph) the steering wheel began progressively rotating counter-clockwise with the vehicle remaining straight. The dynamic stability control turned off as if the vehicle was out of control and the vehicle acted as if it were on icy/slick surfaces no longer providing support to the driver. The braking system began to struggle nearly causing an accident on the off ramp of the expressway causing a fishtail with the ABS attempting to engage. At this point the steering wheel was registering straight' with the steering wheel turned approximately 30 degrees left. Somehow at speeds less than 15 mph the vehicle was driven to the local Mazda dealership where it has a service history for an emergency service inspection. A test drive with a service representative supported the owner's complaints of a severe safety concern with right turns causing a significant 'grinding'/metallic dragging sound as if the vehicle's right under-side was contacting the ground. After inspecting the vehicle in the lift the mechanic determined there was front passenger frame metal corrosion which was breaking off in chunks. The dealership voiced awareness of another 2009 Mazda6 with similar miles (approximately 15,000 fewer) having nearly the same issue last fall/winter. The vehicle in this report has approximately 189,000 primarily highway miles and is otherwise in excellent condition for its year/make/model. The aforementioned frame failure should never happen and is believed to be a manufacturer defect which should not be the responsibility of the owner. Fortunately in this case there was not an automobile accident/collision, injury, or death though this could have easily happened. I do believe there is an extremely serious problem here and needs to be investigated as human lives are at stake.

Steering safety issue urgent. Vehicle was being driven on a highway when suddenly lost steering, front end of vehicle elevated upon turning steering wheel when it was stopped and stationary. Subframe of vehicle rotted prematurely allowing steering linkage attached to subframe to become detached. Vehicle unsafe and required tow to dealership. Dealership inspected vehicle and reported subframe needed replacement in order to fix safety issue - car not able to be driven until repair complete. Vehicle had been serviced at same dealership for years and issue never reported with subframe. This is an extremely unsafe condition for these vehicles. Technician verbally reported that premature rust/rot could be due to location of ac condenser drain line. Subframe replaced with new Mazda oem subframe. Friend with same make/model/year recently reported same issue with subframe.

The contact owns a 2009 Mazda 6. while the vehicle was at an independent mechanic, it was diagnosed that the engine cradle was defective due to severe corrosion and needed to be replaced. The vehicle was not repaired. The vehicle was taken to the dealer for the repair; however, the parts were unavailable for the repair. The contact was informed by a Mazda representative that this was a known failure with that particular model vehicle. The manufacturer was made aware of the issue. The failure mileage was approximately 220,000. The VIN was not provided.

The sub frame on my 2009 Mazda 6 broke while my husband was coming to a stop, which nearly caused an accident. He was able to drive it at a very low speed to a nearby service station. They were able to get it on a lift to survey the damage - it had a severely rusted sub frame that broke and had to be replaced. He was on vacation and had to have the car towed 300 miles to our local Mazda dealer. The local dealer said "they had never seen this", we also have contacted Mazda, several times they have blatantly ignored us. The car has been well maintained, I am the original owner, the body of the car has no rust !
