2011 Mazda MAZDA6 Problems

What owners report

Owners of the 2011 Mazda6 most often report rust and corrosion of the front and rear subframes, which in many cases was found at inspection, state safety inspection, or when steering or handling suddenly changed. Beyond that, complaints describe repeated low-beam headlight bulb failures, a sticky or melting dashboard on the passenger side, and air bag warning lights or air bag performance concerns after recall work. Most reports arrive well past 60,000 miles, though the lighting, dashboard and some air bag complaints appear much earlier.

1. 1
   Suspension

   Rusted-out front/rear subframe (crossmember)

   • 58 complaints (43%)
   • median 108,000 mi at 9.8 yrs old (23 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2018–2026

   Complaints describe the front crossmember or rear subframe rusting through, sometimes leaving visible holes near the spring mounts. Owners report the steering pulling or wandering, loud metal noises when turning, the lower control arm breaking away, and in some cases the rear wheel or crossmember collapsing while driving. Many say the front crossmember was replaced under a recall but the rear was not covered, and dealers or independent shops told them the part needed replacement and that the vehicle was not safe to drive. Typically reported between roughly 85,000 and 200,000 miles, often on vehicles that had already had the front crossmember replaced under recall.

   Recall 19V323000

   What to check: Have the subframe and crossmember inspected from underneath, front and rear, especially on cars from salt-belt states, and ask whether the front crossmember recall work (19V323000) was performed and whether the rear was checked at the same time.

   “Recently while driving down a straight road about 35 MPH my steering started to fail in order to keep the car going straight the wheel has to be turned to the left and held in place. The indicator lights came on that my brake assist system is off/failing. The car slightly jerks to the right when trying to stay going straight. There was noise coming from under the car when turning and going in reverse. …”

   “While driving on the highway at about 55 MPH I heard a loud noice and the car suddenly started to swerve, the steering became difficult. I was able to slow down and pull off the highway and to a parking lot. During the ride at a much slower speed around 20-25 very loud noises came from the right front of the car especially,when the the wheel was turned. The vehicle is not drivable and had to be towed. The sub frame rusted out and the lower control arm pushed the right front tire into the back of the wheel well.”

   Exterior lighting

   Low-beam headlights failing repeatedly

   • 13 complaints (10%)
   • median 55,000 mi at 4.5 yrs old (9 state mileage, few)
   • filed 2013–2022

   Owners report low-beam bulbs burning out within months, sometimes with both sides going dark while driving. Several note that rapping on the headlight housing makes the lamp come back on temporarily, and one report mentions melted or burned wiring that a simple bulb change would not fix. Dealers were described as treating it as normal or suggesting tapping the housing. Reported from about 12,000 up to 76,000 miles, with several owners saying replacements were needed yearly or more often.

   What to check: Check both low beams and inspect the lamp housings and connectors for discoloration or melting; ask the seller how often bulbs have been replaced.

   “I purchased this car in may 2016 with 68k miles on it. First month replaced both headlights because the drivers side went out. Figured ok no problem normal situation, replaced both due to good practice you don't just replace one. Fast forward 3 months later, think it was almost thanksgiving. It was getting dark, and I figured ok it seems way darker than it should. I pulled over to realize, I had no headlights. …”

   NHTSA complaint #11245130, filed 2019-08, 76,000 miles

   “The passenger headlight will go out on my 2011 Mazda 6 even though the bulb and fuses are still intact and working properly. It worked when I parked my car and turned them off manually and then did not come back on the next time I started my car and turned the lights on. It is definitely a flaw from Mazda as numerous people have had this same problem. It is not only the 2011 models, search for Mazda headlight issue and a variety of the Mazda 6's are having this same issue.”

   “Had an head on car accident on the street my tire blow out and hit a light pole. The passenger air bag did not come out, also the driver airbag came out but it was deflated no air was in it or what ever makes an air bag blow up. In which cost me to hit my head on the steering wheel.”

   NHTSA complaint #11326689, filed 2020-05, 187,000 miles

   “I am having various issues with my Mazda 6. First, I have had the car 4 years and have replaced the headlights 4 times. I was told by the dealer it was normal. My major issue is the air bag light. Had a problem back in july with the light flashing. Dealer determined it was the pad sensor and I had it replaced. Now the air bag light is flashing again and dealer now thinks it is the srs control module. The pad sensor was $200.00 and this sensor is over $500.00. I am not sure why air bag components would need to be replaced after 4 years. …”

   “Sometime around the beginning of june I thought my children had spilled something on the passenger dash by the windshield. It turns out it is not a spill, the dash is sticky, shiny, and it is soft and melting. I can stick my nail into the dashboard; it is like hot black asphalt where you walk with heels and the heel goes into the black asphalt. Since I realized this, the area that is soft, sticky/melting is progressing farther down the dash toward the glove box. My car has 46,000 miles and is out of warranty with Mazda. …”

   “The AC compressor clutch locked up and caused the belt to make loud screeching noises. Also, something burning could be smelled inside the engine and burnt rubber was flung around the engine compartment. Another issue: read about this a lot because I am experiencing it, the passenger-side dash is melting. Seems they used a cheap material and when it gets above 80 degrees outside the dash begins to melt. It is sticky, leaves a residue on your fingers, and produces an extreme glare. The AC went out while I was in the drive-through ordering food. …”

   • 8 complaints (6%)
   • median 64,298 mi at 2.6 yrs old (7 state mileage, few)
   • filed 2012–2021

   Complaints describe door latches that do not fully engage, doors that unlock when the outside handle is pulled, and the alarm going off on its own while parked, mostly in warm weather. Some also report key fob batteries draining quickly and difficulty powering the car off. Owners describe dealer responses as limited or unable to resolve the behavior. Reported between roughly 50,000 and 147,000 miles, with alarm and fob issues appearing more in warmer conditions.

   Recall 13V425000

   What to check: Lock and unlock each door several times and check that the latches hold firmly; ask whether the door latch recall (13V425000) was completed and whether the alarm has triggered on its own.

   “I had to replace the batteriess on both remotes that open the doors at least 4 times a year since I owned the car. I feel this is a safety hazard since I can not get in my car unless I use the key. I also have no access to the emergency button on the remote with a dead battery.”

   “When you put the vehicle in park and press the engine button the car does not turn off, you have to move the shifter back and forth several time to get the car to power down.”

Buying note. A pre-purchase inspection on a lift is the single most useful step for this model year, with attention to front and rear subframe corrosion and which recalls have been completed. Budget for cosmetics like headlights and the dashboard, and ask for recall service records on the passenger air bag inflator.
