- #11728337March 31, 2026FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was pulling into a parking spot and the emergency braking system applied the brakes very forcefully as if a collision was imminent. I backed up and saw nothing in the parking spot and then proceeded to pull back into the same spot with no issue. There was a loud and rhythmic thumping sound that I perceived as the abs system engaging. This is a rental car so I am returning it to the company, National rental car, and swapping out for a new vehicle. I contacted Mazda about this and was given a case # 00434431.

I am reporting a potential safety-related defect in my 2025 Mazda CX-50 Preferred, which is approximately four months old. On one occasion, the vehicle moved backward while in Drive mode. This occurred twice on the same day under similar conditions on a slight incline. After starting the vehicle, I shifted into Drive and applied acceleration; however, the vehicle moved backward instead of forward. The rearward motion continued despite active acceleration input. This behavior is not consistent with normal rollback on an incline. The continued backward movement under acceleration indicates a possible issue with transmission engagement, gear recognition, or electronic control systems. I reported the issue to an authorized Mazda dealer. I was informed that shifting the gear too quickly may cause a delay in system response, resulting in the vehicle behaving as though still in Reverse. I consider this explanation unacceptable for a modern automatic vehicle and indicative of a potential defect. This condition presents a safety risk. Unintended rearward movement while in Drive could lead to collisions, especially in situations involving other vehicles, pedestrians, or objects behind the vehicle. Although the issue has not reoccurred since that day, the intermittent nature raises concern about reliability and the potential for recurrence without warning. I request that this issue be investigated as a potential safety defect.

After about six months of ownership, a knocking noise started happening from the front of the vehicle when turning the wheel all of the way to the right. A month or so later I brought it to a Mazda dealership in Green Brook, NJ. I was told by the service advisor that she had the same vehicle and was advised that this was normal. She explained everything exactly as I had experienced it. She told me I could wait in the dealership for 3/4 hours, but the technicians would most likely just tell me the same. Over time, the suspension deteriorated. Bumps felt more and more noticeable and a lot of noise inside the cabin. Specifically, a lot of vibrating on the right side of the vehicle: windows, front passenger seat, and the trunk window. Looking over the internet, it seems like this problem is apparent in multiple vehicle years, but never properly addressed via a recall: [XXX] . The vehicle is currently in Sansone Mazda in [XXX] . They replaced the right CV and the problem did not go away. I was told they would have to contact Mazda corporate. They did and I was then advised that they would need to replace the left CV axel, as well. Not surprisingly based on the frequency of this issue, that part was unavailable and on back order. I don't know how long I'll be without my car at this point. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

- #11727435March 27, 2026AIR BAGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I am reporting a potential airbag system/emergency brake failure in my 2023 Mazda CX-50. I was involved in a rear-end motor vehicle accident at approximately 60 mph while my vehicle was completely stopped. I then hit the person in front of me. At the time of the impact, the airbags did not deploy, and I received a dashboard message indicating an airbag system malfunction. Since then, the emergency brake turns on and off on it's own at any time. Due to the severity of the crash, I am concerned that the airbags should have deployed, and their failure raises a serious safety concern. I sustained injuries (multiple fractures) as a result of the collision. I am requesting a formal investigation into possible defect or malfunction in the airbag system and emergency brake system.

There is a recall for earlier models regarding "break clunk." The parking break, when sitting overnight in cold or wet environments, makes a loud bang noise when going into motion for the first time. The parking break seems to be sticking to something.

On 02/27/2026, a 2024 Mazda CX-50 (20700 miles) exhibited a severe burning smell following a 3-hour highway drive and a subsequent steep, 2-mile mountain climb to a restaurant in Jasper, TN. The smell was strongly observed by multiple occupants upon exiting the vehicle. On 03/02/2026, a technician at Mazda of Knoxville confirmed via video a 'flat grease ring' slung onto the undercarriage, indicative of a centrifugal lubricant leak from the driveshaft/CV assembly. The proximity of this flammable grease to the hot exhaust system during high-torque operation (mountain climbing) presents a critical fire hazard. Despite visual confirmation of the slinging grease, the dealership issued a blank service invoice, omitting the defect from the official record and returning the vehicle in an unsafe condition. This represents a documented safety defect being suppressed by the manufacturer, posing an unreasonable risk of vehicle fire or catastrophic driveline failure.

- #11723051March 9, 2026TIRES
The tire on the front driver's side was bad. I had it assessed at Ogeen K auto and he said they put a used tire on the vehicle. The other three were brand new. The noise I was hearing was coming from the tire. And was causing the vehicle to pull. My safety was put at risk because Iwouldd need a longer stopping distance. Sliding, the vehicle pulling to one side, and the spare tire was missing. They covered the hole with a piece of cardboard. I spoke to the employee at Hertz and told him the day he gave me the vehicle. There were no lights or warning lamps on.

Driver side and passenger side axle-area, making loud clicking and popping sounds on turns indicating major damage to CV joint, at around 10,000 miles. Primarily heard on sharply turned wheel acceleration. Two dealerships said they "couldn't reproduce the issue" even though I showed them the issue on recorded video. I demand that this be taken seriously as a recall.

The driver's door is not opening from the inside. To open the driver's door while I am in the vehicle, I have to roll down the window and use the exterior door handle to exit the vehicle. This is a huge safety concern, as the window cannot be rolled down manually. If the car did not have power, I would have to break open the window. The potential for being trapped in the car with this defect is high.

At only about 6,100 miles and during my vehicle’s first service, the technician found grease leaking from the left front CV boot. The dealer stated this was caused by an external puncture, but they were unable to provide clear evidence, detailed photos, or a written diagnosis proving that the damage was external. The mark they referenced was extremely small and not consistent with a clear impact. A CV boot should not fail at such low mileage, which raises concerns about a potential early-life component failure or material defect. A torn CV boot can lead to CV joint wear, loss of power, or loss of vehicle control if it progresses. Because the root cause is uncertain and the failure occurred unusually early in the vehicle’s life, I am reporting this to NHTSA in case this represents a broader quality or safety issue affecting other vehicles of the same model.

Vehicle: 2025 Mazda CX-50 Hybrid Mileage at first failure: ~6,000 miles Component: Front CV boot / axle assembly — loss of grease Safety Concern: Early-life component failure with unresolved uncertainty in root cause Description: At approximately 6,000 miles, the left front CV boot of my vehicle was found leaking grease. The dealership initially stated the failure was due to “external impact,” but no conclusive evidence was presented to support this determination. The photos and inspection notes did not identify a clear puncture or specific point of impact. Mazda Corporate later informed me that their engineering team concluded the issue was not related to a material or manufacturing defect, and offered a goodwill repair. However, the underlying root cause remains uncertain due to the lack of definitive evidence. Safety relevance: A CV boot failure at such low mileage is extremely unusual for a modern vehicle, and premature loss of grease from the CV joint can lead to: joint degradation, reduced steering stability, potential loss of vehicle control. If similar early-life failures occur on additional Mazda vehicles, this may indicate a broader design, material, or assembly concern. Requested Action: I am submitting this report for documentation purposes in case a pattern emerges or if the issue recurs on my vehicle or others.

I brought my vehicle to Modern Mazda of Thomaston, CT on Friday January 30, 2026 due to a front-end passenger clunking noise that occurs during left turns. The master tech test-drove the vehicle to duplicate the noise and video of the damage. I was informed that the front passenger axle was leaking grease in video and recommend to replace the front axle. I was told the necessary parts are on back order 6-8 weeks. I was told Mazda is aware of the manufacturer workmanship defect in the CV axle parts. The service manager did provide written documentation ordering the parts. I did file a complaint with Mazda Corporate, documenting the issue and the dealership's findings as well as I was informed the fact Mazda is seeking a new supplier of CV parts. A Mazda corporate case number was assigned. I believe this is a safety issue and a recall should be issued.

On December 3, 2025, the front seat of our 2025 Mazda CX-50 Hybrid caught fire while the vehicle was being used under normal conditions. The fire originated inside the seat, causing visible burning, charring, and damage to the seat material. This incident occurred approximately 6–8 weeks after purchase. The vehicle was brand new at the time of purchase and had not been modified, misused, or repaired prior to the incident. The fire occurred inside the passenger compartment, creating a serious and immediate safety hazard. Had the fire spread, it could have resulted in severe injury or death. The incident caused fear for occupant safety and required immediate action to prevent further damage. ehicle Use and Conditions The vehicle was being operated normally No collision or external fire occurred No smoking or open flames were present No aftermarket modifications were made The vehicle had low mileage consistent with recent purchase Repairs and Manufacturer Response The vehicle was taken to the dealership. The dealership has stated they will replace the damaged seat and return the vehicle. However: The exact cause of the fire has not been clearly explained It is unclear whether the fire was caused by: Seat heater malfunction Electrical wiring defect Short circuit Hybrid electrical system component Replacing the seat alone does not address whether there is an underlying electrical or manufacturing defect that could cause a recurrence. Safety Concern A fire occurring inside a brand-new hybrid vehicle’s seat presents an unreasonable risk to occupants. This defect substantially impairs the safety of the vehicle. There is ongoing concern that the issue could happen again, potentially with more severe consequences. We are submitting this complaint so the issue is documented, investigated, and reviewed for potential safety defects affecting other vehicles. I
