* 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.

Car suddenly veered right on the highway and scraped both fenders and the mirror against a cement barricade. Steering has been unpredictable. While elevated on jack stands with both front wheels hanging, crouched facing the right passenger side tire, the tire can be gripped with the left hand on the rear facing tread and right hand on the front facing tire tread, then moved in and out with large amounts of play, wobble, and clunking noises. There is also a large amount of noise and clunking coming from the area where the streering " linkage" ( term?) connects to the hydraulic rack when the front of the car is on jackstands and the steering wheel is moved to both extremities. The hydraulic steering rack appears to flex left and right when the car is on the ground in the normal driving position and the steering wheel is moved to both extremities. The left drivers side wheel bearing is in need of replacement. While assessing that is when the extreme rusting of the front subframe was noticed, along with a huge rust hole on the right passenger side as described by others. Very close to the attachment of the lower A-arm of the same side. Car was purchased new from dealership with 1500 miles by an in household family member and has had all/nearly all of its scheduled dealership maintenance at the place or purchase up untill the beginning/middle 2017. Afterwhich I recieved the vehicle. This was all noticed on or aprox July 1st 2018 and the car hasnt been driven since.

This car was bought used. After suspension inspection I found out that the front subframe is extremely rusty and immediate replacement is necessary. According to the body condition there were no any incidents which may affected the subframe condition. Further driving with this is dangerous.

In August 6th, 2018, I was driving back from work with my 4Y old son in quebec city at 50 km/H. when I want to stop at the red-light I sensed a significant loss of steering control to the right and I was completely shocked because I was just about to hit a cyclist. And my son was frustrated too. Luckily nothing bad happened. But from there I wasn't able to drive correctly, I held the steering wheel to 60 degrees to the left while going at 25 km/H to be able to drive straight and get back to my home. The following day I drove my car to the nearest garage, and to my surprise, the guy told me that the subframe at the right near to the wheel is completely corroded and the steering rack was separated from its mounts causing the steering loss. The garage owner told that he called Mazda to ask for a new subframe for me, but they told him that they don't have it in stock and they have already 5 more people with the same problem waiting for that. Knowing that I do rust check and treatment before every winter. I am very thankful to god that nothing bad happened while I was traveling with my family during our holidays. Mazda should recognize this as a serious and very dangerous defect since it is happening for a lot of people.

I bought a used car with 2 dashboard light tmps & engine the dealer give me extra warranty but never been repair furthermore I find out by myself a recall for the outer door handles after the door open while I driving in the express way this happened to my youngest daughter; and in other 2 incidents the car do not respond with the appropriate speed causing me a big chance of accident afterwards it is happened again so due to other several mechanic problems and for security I have to decided to return the car now I have no money no car and a big problem I am having hardly time tried to summit my concerns because I think the dealers are responsible for sale security cars before the sale but apparently the laws are in the dealers side as a consumer I hope maybe some one can see how this irresponsible dealers play with the consumers safety. I pay over $3,000 in repairs by my self and I have been around 90 days with out car and all this problems in a period of time of 26 months plus my payments to the dealer that was $460,00 a month this issue start on 12-6-13 to 02-26-16 after the car need a new repair at cost of $3,000 so in the reality this company was negligent when they fail to properly repair the car since the beginning they just pretend to fixed but wasn't. I want to thank you for your time.

2 valve stems from the TPMS sensors are leaking air. That provoked an instant loss of total air pressure in the tires !!!! this is extremely dangerous if it happens on the interstate at high speeds. It seems Mazda has a service bulletin sb-02-001-12 but not a recall at this time (March 4 2015) from 4 TPMS sensors on the 2009 Mazda 6, two (2) of them failed one day after another. Both sensors failed at the valve stem. Had to replace all 4 sensors due to being afraid this sudden loss of air pressure could happened at 60 miles/H on the interstate. The manufacturer of the TPMS sensors is Continental and they already have a different part # for the sensor (Continental vdi redi-sensor se10001hp-AZ). Also Mazda has a different part # for the new sensors: Bbm2-37-140B. I was surprised how Mazda didn't issue a recall by now. I've seen plenty of other people complaining about this on online forums or websites specialized in car issues.

During normal use, valve stem broke halfway down the stem which required replacement of the valve stem and tire pressure sensor on that one wheel.

Driving on I-94 West, near ann arbor, mi. Felt vibration, then left rear tire blew. Managed to pull to the shoulder and changed tire. Inspected damaged tire and noticed valve stem and sensor were missing. The next day checked the other tires for proper inflation and when I tried to remove the valve cap from the right rear tire, it blew off with the core stem and the tire went flat. Had both tires repaired, new sensors and tire. I had new tires installed on 1-11-14 and two sensors were changed at that time. So three out of the four sensors failed with one blown tire.

I understand that the car isn't under warranty anymore; however, how was I supposed to know that my rim would crack as I'm driving. Like I said a million times to so many people, I did not hit a curb, or a bump for the rim to crack. I have one rim issue and all the others are just fine. This is my rim story from the beginning to the end... in the week of August 15th-21st, 2010, the tire pressure warning light came on all of a sudden. I got nervous and I noticed my front-right tire was somewhat low. I went to pep boys to have air put into the tire. A few days later, the light appeared again and I went to another pep boys to have air put into the tire. The warning light disappeared after it was worked on. Then the warning light appeared again after a couple of days and I went back to pep boys to have the front-right tire checked again. The young man said to me, "miss, there is a crack inside of your front-right rim." I made an appointment to another dealer who repairs rims and repair my rim. Everything was fine after the rim was repaired. Then I received a letter from Mazda corporation about recalls. I had those done and the dealer said, "I need to get my tires checked again." I left the dealer and went to Firestone and they repaired the cracked rim (2nd time). On January 11, 2014, my aunt and I returned from food shopping around 3pm. I parked the car at my aunt's house to unpack the food from the trunk. My aunt, cousin and I were getting some of the food out of the car, when all three of us heard air (whoooooosh) being blown out of a tire for about 20 seconds. We all stood still and looked to see which car the air was coming from. Then my cousin look at my car said, "[xxx], do you know you have a flat?" I just could not believe this was happening again! when I saw the tire flat as a pancake and the rim touching the ground, I was shocked and upset.

For the second time in a year the air valve on one of the tire pressure sensors on our Mazda corroded and snapped off as I was putting air in the tire. I'm very grateful this happened while the car was in our driveway and not while my wife or daughter was driving the car.

Tire pressure sensor failed while traveling down highway, when finally able to pull over tire was completely flat and ruined, valve stem fell apart in hand while trying to remove valve stem cap, this is the 3rd occurrence while owning this vehicle, very lucky this time that it was a back tire and not a front. Each time that I have complained to dealership, I am told that the tire shops that are replacing my tires don't know what they are doing of which I disagree. I have seen many forums regarding this issue with Mazda 3's and 6's, each time being told the tire shops don't know what they are doing. Mazda needs to step up and acknowledge a poor design, come up with a better one and recall these bad tire sensor valves before someone is seriously injured or killed.

When I went to go remove the valve stem cap to check the air pressure, the valve stem broke off with the valve cap revealing the valve core. The tire was deflated within seconds. Further inspection of the valve stem showed that it was corroded. The valve stem broke off exactly at the point where the cap was screwed to. The dealership did not cover the cost for repairs as my car is not under warranty anymore. The cost for repairs came from my pocket.

While driving at 55 mph, the low pressure warning light came on. I attempted to get to a safe place to check my tire but the tire went flat too quickly. I had to change the tire on the road. The tire pressure monitoring device had failed and fallen inside the tire resulting in a rapid pressure drop. Corrosion had caused the nut to break apart and fall off. Within 6 months the same thing happened on a different tire. Driving at 55 mph, the warning light came on and I immediately pulled over to watch my tire rapidly going flat - all within about 20 seconds. I changed my tire on a very busy highway. I was lucky that this did not happen on a multi-lane thruway. This is a very serious safety hazard - the mandated safety device is the cause of the hazard.

Valve stem cracked then completely broke off under the plastic cap. The tire pressure warning light had been coming on 2-3 days prior to incident. Each morning when cold during first start up light would come on, after a few minutes of driving after vehicle warmed light would turn off. On way home from work traveling 70mph light came back on. Took the next exit and stopped at gas station to fill up tires, removed valve stem cap and installed air hose. Air hose could not fill up tire, air just came out of the side of stem, reinstalled valve cap. At that time we didn't know the stem was cracked so I drove the car very slowly approx 3 miles to my parents house so my dad could help. He tried to remove the valve cap, at this time the stem completely broke off at the threads and stayed with the cap. The stem internal parts sprang out so it was necessary to remove the tire and install the spare. We took the tire to nearest belle tire so they could replace the stem but since it was a dealer only part all they could was replace it with a standard rubber stem with no sensor. They mentioned it was a common problem they had seen before, to which I was very surprised. These sensors were created to combat low air pressure after the "tread act" and ironically are causing a low air pressure. The original cause of the pressure light was due to a slightly bent rim on the inside. This had a slow leak after belle tire replaced the stem. We took the tire to brighton Mazda the following day to replace the sensor, they too said they had seen cracked stems in the past. Please look into this and determine if this is a safety issue. I think its very ironic this is happening when the free rubber stems almost never fail and $70 sensors are breaking on a 3 year old car.

The contact owns a 2009 Mazda Mazda6. The contact stated that the passenger side rear tire valve stem was corroded and causing the tire to go flat. The vehicle was taken to the dealer who advised that there were no recalls on the tires or the valve stem. The failure was experienced twice. The dealer first repaired the vehicle at the dealers expense but denied assistance with repairing the vehicle a second time. The manufacturer was not made aware of the failure. The failure mileage was 26,000 and the current mileage was 37,000.
