MAZDA Complaints

While coasting slowly through a parking lot at approximately 5-8mph I tapped the brake to slow further while making a tight turn and to safely pass a vehicle also turning towards me. This caused the car to lurch and accelerate as though my foot was on the gas pedal, but it wasn't. I had to step hard on the brake to bring it under control.

After starting the vehicle and driving it for a short distance, I forgot to disable the engine start/stop function. When the engine shut down, I pressed the button to disable it as I loathe this feature. The button would not respond, resulting in the engine repeatedly shutting down during coasting events and limiting the functionality of my AC. I tried multiple times during my 45-minute drive to disable it, but was unable to. I shut the vehicle off and restarted it when I was safely stopped. The system worked as intended after this action. I have never had a car with so many technology bugs and electronic safety system issues as this one.

While attempting to change lanes on I-75 southbound, one lane to the left of my current position, I was enforced and the steering wheel pulled back to the right. I was navigating a right-hand curve on the interstate and moving past slower traffic at 81 mph. My turn signal was activated, the lane departure system deactivated, and the signal was still flashing as the lane change was executed. The turn signal should suspend enforcement as well as the system being deactivated. Both interlocks failed to operate. No other vehicles in the area would've contributed to this event. The lane departure "off" warning light was on the dash, indicating that the system was not operational. I was not firmly holding the wheel and allowing it to glide effortlessly through the lane change to execute my plan when it jerked back to the right.

I was operating the motor vehicle at roughly 60 mph on a two-lane divided highway around 830AM. I was driving toward the sunrise to the east and passed under a highway overpass. As I cleared the overpass from the shade back into the sun, the vehicle flashed a collision warning on the windshield and immediately applied aggressive braking for no reason. No other cars were in the area around me at the time of the incident. Had someone been following me too closely, this would have likely resulted in a rear-end collision. Safety system malfunctions are frequent and unexpected. It is always something, and this isn't the only time it has happened. It has simply annoyed me enough to cause me to submit a report.

I recently purchased a 2023 Mazda CX9 with factory installed tires, Falken Ziex CT50 A/S p255/50R20 104V M+S. I was driving on the freeway on Tuesday [XXX] going around 65-70MPH. My tire pressure light came on all of a sudden, I started to slow down and make my way over to the right lane and then shoulder to check it out and all of a sudden the tire tread completely ripped away from the rest of the tire. Some of the sidewalls stayed intact, which ultimately protected my wheel from damage. But other than the tire pressure light coming on 30 seconds before the failure, there was no warning, no obvious defect or anything in the tire. Had it been one of my front tires it potentially could have been way worse of an outcome as I was driving on a bridge and next to a semi. The shop where I ended up replacing all 4 tires because I did not feel safe using this brand any longer said he has never seen the tread just rip right off of the sidewalls. I searched the tire make and model and there was an open recall on this specific brand and size tire, but my date stamp did not match. However, it was the same exact reason for the recall in the first place. So clearly this company has not changed their manufacturing methods and is putting people's lives in danger with these tires spontaneously detaching from the wheel.

To whom it may concern, I was on a back road late in the evening not far from home [XXX] and a small deer ran into the road. I needed to brake to avoid hitting the deer. After breaking, a Brake System Malfunction warning message and i-ACTIVESENSE System Malfunction warning illuminated on my dashboard. I brought the car to a Mazda dealership the next morning. The technician determined that the brake fluid level sensor became stuck, requiring replacement of the brake fluid reservoir and the brake fluid level sensor. What failed: The repairs include replacement of the Brake Fluid Reservoir and the Brake Fluid Level Sensor. This is the link to the dealer report [XXX] . No one other than the dealer has inspected these parts to my knowledge. There was no accident of any kind. I personally felt unsafe after these parts failing and reached out to Mazda Customer Care to request investigation of the issue. The case manager just called me back today to say they could not help me. Mazda has denied warranty coverage, claiming the parts are not covered. However, I really do feel this is a critical safety system component that failed after normal emergency use with no collision or impact. Why I feel this is a safety concern: - The brake warning system became unreliable after a single emergency stop. - My car only has 42k miles and is in excellent condition and is fully dealer serviced. - A driver could lose the ability to receive proper brake system warnings if this failure occurs again. - A critical brake sensor should not fail under normal driving conditions, and its failure could lead to delayed driver response in an actual brake fluid loss scenario. It makes me worry for the future. For your consideration: I believe this represents a safety-related defect that should be investigated, as it affects the reliability of the brake system warning indicators in the 2019 Mazda 3. I appreciate your time and consideration. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to formally report a serious safety issue with my 2016 Mazda 3 manual transmission, which experienced a sudden and complete clutch failure at less 60,000 miles — without any warning lights or diagnostic alerts. I am deeply concerned that: •There was no dashboard warning, even as the clutch system failed •The gear indicator was inaccurate in prior days, which may have been an early sign of failure •There was no protection mechanism to prevent complete drivetrain failure during normal use.

On multiple occasions I have had driver assistance system failures with the most recent occurring this past Saturday 8/2/25, which I have on dashcam. In this incident, I had adaptive cruise control set to short following distance. I had about 5 or 6 car lengths in front of me at highway speed and the lead car was far enough ahead that the car was not showing it on the interactive display. Another car changed lanes from the right to left in front of me right behind the lead vehicle. The car that changed lanes was not detected by the vehicle even though it was right in front of me. I was approaching the vehicle at a higher rate of speed and the car never attempted to slow eventually requiring me to depress the brake to cancel the cruise as the car was not responding to the fact that I was now right behind the car and had to brake to avoid a collision. On a separate incident a month or so ago, I was entering a center turn lane, waiting to turn into a gas station which required crossing of 2 lanes of traffic in the opposite direction. As I was entering the center lane with my signal on, the car detected the opposing traffic and slammed on the breaks nearly causing me to get rear-ended by the traffic behind me that expected me to enter the turn lane at the rate of speed I was going. Routinely, the car fails to detect vehicles in the blind spot. I can approach, pass, and clear a vehicle on the left (vehicle to my right) and the car will never detect that a car was there in the first place. Additionally, if a car is detected and then stays in the blind spot long enough, the car loses it and thinks the car is no longer in the blind spot.

My 2007 mazda5 power steering stopped worked abruptly while turning on a major highway. The sudden change in steering nearly caused an accident. I checked the ODB reader for codes but none were present. Then it happened again the next day in a similar situation, the power steering shut off but this time we were able to see the dash light for the power steering failure come on. It kicked back in a minute later. Again no codes in the scanner. Upon researching how to fix this issue my search revealed that 2007-2009 Mazda 5s have a recall for this exact critical failure. My next step was to call the local dealership to schedule a fix, however they told me that our specific vehicle (according to the VIN) was not under that recall, regardless of the vehicle doing precisely what was recalled. Please review the recall if you can, this is likely affecting more vehicles than Mazda is admitting to and is extremely dangerous.

I am receiving recall notifications and service alerts for a Mazda vehicle that I do not own or have never authorized. I am a victim of identity theft, and it appears a vehicle may have been fraudulently registered or associated with my personal information. I have no connection to the vehicle being recalled and have reported this identity theft to the FTC, local police, and the California DMV. I am submitting this report to request that my personal information be removed from any vehicle records associated with this recall. I’m attaching supporting documents, including my identity theft FTC reports, police report, DMV reports Please advise on next steps to ensure my information is not used in connection with any unauthorized vehicles.
