Mazda is facing a proposed class action lawsuit over allegations that certain CX-90 SUVs are equipped with defective braking components and lane-keep assist systems that may operate unpredictably, potentially affecting vehicle control and driver safety.
What is the problem?
The lawsuit concerns 2024-2026 Mazda CX-90 vehicles, with plaintiffs claiming that the braking system in these SUVs may experience premature and excessive wear, leading to persistent brake noise, including loud squealing and grinding sounds during normal driving conditions.
Alongside the brake concerns, the complaint also targets the CX-90’s lane-keep assist technology. According to the allegations, the system can apply steering corrections that are overly aggressive or inconsistent with the driver’s input, in some cases causing the vehicle to subtly resist intended steering movements.
The lawsuit claims these defects create a broader safety concern, particularly if braking performance is degraded or steering assistance behaves unexpectedly during routine driving situations such as highway travel or lane changes. The plaintiffs further allege that Mazda was aware of these issues through pre-release testing data, dealership reports, and consumer complaints, but did not fully disclose the nature or extent of the defects at the point of sale. The complaint argues that buyers were led to expect a higher level of refinement and safety from a premium SUV platform than what was delivered in real-world use.
What owners should do
Owners who experience unusual brake noise, vibration during braking, or inconsistent steering assistance should arrange an inspection with an authorized Mazda dealership as soon as possible. It is also advisable to retain records of all repair visits, diagnostics, and communications with the manufacturer, particularly if issues persist after servicing.
Owners can check for any related recalls or technical service bulletins by searching their Vehicle Identification Number (VIN) through the National Highway Traffic Safety Administration (NHTSA) database.
How Mazda owners can take back control
When core safety systems like braking and steering assistance become unreliable, it can quickly turn everyday driving into a source of concern. Even intermittent issues may leave drivers uncertain about how their vehicle will respond in critical moments.
