What owners report
“The rear differential makes a grinding, clicking noise when traveling at low speeds and especially when turning. After a fluid change the on the differential, a large amount of metal fragments were visible in the oil. Also causes rear wheel hop on sharp turns. This is a known issue amongst CX50 owners but Mazda refused to acknowledge an issue. The issue started for me around 40k miles. Just outside the warranty period.”

“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 …”

“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 m…”

“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 note…”

“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 co…”

“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 p…”

“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, suggest…”
