In a move that could have significant implications for automakers, the owner of a 2024 Mazda CX-90 has taken legal action against Mazda, alleging the company failed to properly address an ongoing brake noise issue. At the center of the case isn’t a complex mechanical failure but a high-pitched brake squeal—loud enough, according to the complaint, to cause public embarrassment and raise serious safety concerns.
The plaintiff claims the shrill sound produced when applying the brakes is sudden, jarring, and disruptive, particularly during emergency stops. He argues that it not only undermines confidence in the vehicle but also creates potentially dangerous driving conditions.
Early Complaints, Limited Solutions
The issue first emerged when the vehicle had covered fewer than 840 miles (1,352 km). Upon visiting the dealership, the owner discovered that the service team was already familiar with the complaint. They initially lubricated the brake pads and calipers, which reduced the noise temporarily.
However, the relief didn’t last. On subsequent visits, technicians tried further remedies—polishing the rotors and pads, and applying materials meant to dampen sound and vibration. Yet the squealing persisted. Despite multiple repair attempts, the noise kept returning, prompting repeated trips to the dealership.
During one of these visits, a technician revealed an internal Mazda technical bulletin from 2024 that acknowledged the problem. But there was no permanent fix—nor an official recall.
Legal Action on Grounds of Negligence
Frustrated, the owner filed a lawsuit in California, accusing Mazda of negligence and breach of its responsibilities to customers. He contends that Mazda sold a car with a known, unresolved flaw, and that the temporary fixes offered were insufficient. According to the complaint, he spent over $1,500 (5,625 SAR) trying to resolve the issue, with no lasting success.
The legal filing claims that Mazda failed to inform customers about the defect and failed to develop or communicate a definitive solution—leading to an ownership experience described as both stressful and unsafe.
A Widespread Complaint?
Reports from other CX-90 owners suggest this case may not be isolated. Discussions on forums and social media show several drivers have noticed similar brake noise, often likened to “metal scraping metal.” Some owners say Mazda attributed the sound to typical brake behavior in certain environments or as part of the normal break-in process for new vehicles.
Still, critics argue that such explanations fall short, especially when the noise is so loud that it disrupts concentration and contributes to a feeling of instability while driving.
From a Service Issue to a Trust Crisis
While Brake Noise might seem like a minor annoyance, this case illustrates how seemingly small flaws can damage a brand’s credibility. For the affected owner—and many others—what began as a service request has turned into a symbol of frustration, costly repairs, and corporate silence.
If Mazda fails to respond with a transparent and lasting resolution, it may face increasing legal pressure, and possibly, a broader recall. What’s at stake isn’t just noise—it’s consumer trust.
