2025 Mazda CX-50 Complaints

Mazda CX-50 at 22000 miles CV joint on passenger side making clicking sound under moderate acceleration. Scheduled service with dealer on 1/28 received appointment date of 3/2 for inspection and possible repair.

Driver side and passenger side axle-area damage, making loud clicking and popping sounds on turns indicating major damage to CV joint, at around 5000 miles. Primarily heard on sharply turned wheel acceleration, particularly on slightly uphill inclines.

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

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 degrada...

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.
