2025 MAZDA CX-5 Complaints

Breaks and gas pedal simultaneously stopped working while driving and steering wheel locked up

Vehicle CV joints failed at 6000 miles, dealership took over 3 weeks to replace them. They claimed multiple CX50 hybrid vehicles are impacted and lots of them already returning under the same problem

The system that failed was the acceleration. This how it happened the first time, because after that it has happened at least two more in one year. I was leaving my office parking area, and I was waiting for the cars in front of me to continue moving. Then I was ready to start moving and put my foot on the accelerator and just went to a high acceleration. Which I immediately slammed the brakes because otherwise I would have smashed the rear part of the vehicle in front of me. My safety was in jeopardy because if I would have hit the car in front of me and my airbags would have deployed. And the speed of the acceleration was so, that the driver in front of me would have definitely felt it in his neck and God forbids what else!!! Yes, I reported to my dealer, and they said that nothing showed in their computer system, and mentioned something of a throttler not been wrong, (which I don't know what that is). There were no warning lamps or messages in the dashboard prior to the failure. This happened to me again in random occasions where I was just getting my car out of my parking in my condominium, also lucky, it was early in the morning and no cars around. AND the other instance also in my condominium parking area, but this time arriving, and also, lucky no cars near!!!! Your website describes a similar complaint for the same make and model of my car, thus implying that there is a problem with the system.

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.

I get an error that rear side radar obsured, I activsense temporarily disabled almost everytime I drive at freeway speeds. It disables the blind spot monitoring making the vehicle less safe. It disables for long periods of time in all conditions. Took to Mazda and they indicated it’s an issue, but no solution.

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

I am reporting a potential safety-related defect involving premature axle failure on Mazda CX-50 vehicles. The axle appears to be prone to early failure under normal driving conditions, sometimes at relatively low mileage. There are multiple reports from other Mazda CX-50 owners describing similar axle or CV axle failures, including clicking noises, vibration, loss of power to the wheels, and complete axle failure. These reports are publicly documented on online owner forums and Reddit, suggesting a pattern rather than isolated incidents. Axle failure can result in sudden loss of propulsion and may increase the risk of a crash, especially at highway speeds or during turns. This appears to be a design or durability issue rather than normal wear and tear. I am concerned this defect affects multiple vehicles and warrants investigation and a potential recall before more failures occur.

I brought my vehicle to Safford Mazda of Fredericksburg on Monday, December 15, 2025 due to a front-end clunking that occurs during left or right turns. A service representative test-drove the vehicle with me and was able to hear and duplicate the noise. Shortly afterward, I was informed that the front axle has internal damage and that the vehicle would need to be retained by the dealership for repair. I was told the necessary parts would not be available until sometime in February 2026. The dealership retained possession of the vehicle and arranged a loaner vehicle for my use. The service manager declined to provide written documentation stating that the car was unsafe to drive or describing potential consequences of continued operation. However, the vehicle was not released back to me pending the axle replacement. I have filed a complaint with Mazda Corporate, documenting the issue and the dealership's findings. A Mazda corporate case number is available if needed.
