Mazda MAZDA6 grinding brakes problems

Filed Apr 1, 2026 · Transmission · IL

System Failure: The Power Train (6-speed Automatic Transmission) suffered a major malfunction, documented by diagnostic codes P0731 (Gear 1 Incorrect Ratio) and P0780 (Shift Error). The vehicle is available for inspection. Safety Risk: The failure caused a sudden loss of propulsion while attempting to accelerate. This created an immediate risk of a rear-end collision and left the vehicle unresponsive in the path of oncoming traffic. The transmission's unpredictable shifting makes the vehicle unsafe to operate. Confirmation: The failure and the P0731 code were officially confirmed by Castle Mazda on March 2, 2026. The manufacturer (Mazda) has been notified but has denied a remedy, despite TSB MC-10160555-0001 addressing this specific internal defect. Warning Symptoms: There was no Check Engine Light or dashboard warning prior to or during the failure. The only warning was an extreme, abnormal mechanical grinding/clunking noise from the transmission. The lack of a malfunction indicator light (MIL) meant I had no electronic warning of a looming mechanical failure while in motion.

1) UNKNOWN. My guess: The front seats or guard rails. 2) Very seat when braking, and coming to and from a stop. Poses as a safety risk. 3) Yes, no remedy/solution was yielded. Others on forums who visited dealership stated that the dealership said it was “normal”. Despite the other side not having the issue at all. 4) No 5) No Full assessment: The issue of this complaint lies within the front seat of the vehicle. My educated guess is that there is a defect within the seat rails of the vehicle as no remedy seems to be found upon extensive research on google and various forums. Specifically, in my vehicle and may others that I have found, have issues with the driver seat feeling loose when braking or hitting the gas from a stop. Many individuals (including my close friend) have raised this to dealerships and were told that this is “normal” despite the passenger seat (or vice versa) does not have the same issue whatsoever with no remedy. I personally have tightened all possible nuts and bolts for the seat AND brought it to multiple shops and dealerships, which yielded no remedy as all bolts were in fact tightened. I strongly believe that this issue should be further investigated and mitigated as it poses as a risk of serious injury - whether involved in an accident or the seat coming loose, or off entirely. The best way to describe the amount of play is sitting on a chair that is placed on an uneven floor, with one corner rocking toward itself. Or a table that is placed on an unleveled floor and is rocking towards one end (which that remedy consists of folding an napkin enough times to stick it under one of the legs). Please note that I have had this car for a couple of years and this one thing that grinds my gears.. aside from the plastic rattle of the driver side window switch module when listening to music.

Please can someone put in a recall for this my transmission is having problems again and this is my second madza 6... This doesn't make any sense we spend money of vehicles that suppose to run well... So why are there so many people having problems with these madza's and know one is doing anything about it.... I was on the highway with my kids when the car just cut off and wouldn't move and when it did it was started grinding when I put it in gear.... That was a scary thing... The same happened to me in my first madza 6 with only 89000 miles on it... Something needs to be done....

2-3 months ago I noticed that emergency hand brake was not holding the car again after recall has been completed back in sep 2017. Now I always leave my car parked on the 1st gear (manual transmission). My mechanic said that calipers have never been replaced and they look original also he showed me that brake pads are not being released and get stuck really hard on the rear axis. I found the invoice and everything that has been replaced is "parking brake lever per recall order". Also mazda declined fixing/replacing brake pads that have been worn out withing 1 year after I replaced them. They said that this can't be covered since the job has not been done by mazda service and the parts were aftermarket. I had to change pads on the read axis 2 times in almost 1 year and now I have to do it again. Also I hear squeaking noise when I'm driving. I can hear that the pads are not completely released and touching brake disks. Almost a year before the recall my car rolled down the slope and blocked fairly busy road in washington dc. Luckily it didn't hit any car or person.

My vehicle has had strange grunting, squeaking, popping noises coming from the frontend, particularly the drivers side. It has had this issue since I bought the car in june 2017. The noise seems to be worse when driving over small bumps. It's very noticeable when I back out of my driveway. I have addressed this issue with the dealership I purchased my car from. They can't duplicate. I have researched this exact issue and found there is a tsb for the suspension issue I'm describing. I'm just getting worried about my safety. I'm afraid something will fail and I feel it's the manufacturers responsibility to correct this unsafe issue with the suspension that affecting many other mazda 6 vehicles.

I braked quickly for a traffic light. The car skidded and veered violently to the right. When I accelerated from the light, I had to hold onto the wheel tightly to keep the car on the road. If I let go of the wheel, the car would immediately swerve to the right. In addition, the front passenger side wheel was squealing. I got it to my mechanic who told me that the subframe has rusted through and broke. I was shocked as the body has no rust. I have always keep the car very clean and maintained. In fact, I had the under body rust proofed when I purchased in 2009. I had to remove the car from the road as it was undrivable. If I had been on the highway doing 55, I would have been involved in fatal accident.

Was driving vehicle at 45 mile per hour. Suddenly noticed steering wheel was off center. I did not hit a pothole or any other obstructions on the road. Steering became very loose and vehicle hard to steer. When braking the vehicle started to make squealing sound and pulled to one side. Suspension became very harsh even on good surface road.. This is a catastrophic failure with no warning. Fortunately was able to get vehicle to auto repair center without getting into accident. Auto repair facility examined vehicle and showed me that engine cradle - subframe had rusted thought and broke. This caused the engine to go off center which caused the braking, steering, and suspension issues. Auto repair facility told me the vehicle was not safe to drive and made me sign a waiver to release the vehicle.
