Owners of certain Mazda CX-90 SUVs are raising concerns over alleged problems with both braking performance and Lane-Keep Assist, according to a new class action lawsuit. The complaint claims the defects can lead to premature brake deterioration, persistent noise, and unexpected steering intervention that may make the vehicles more difficult to control.
What is the problem?
The lawsuit involves 2024-2026 Mazda CX-90 vehicles and alleges problems with two separate systems. The first concerns the braking system, which plaintiffs say can deteriorate far sooner than expected, with owners reportedly experiencing high-pitched brake squealing, vibration, and juddering during normal braking, with some allegedly needing replacement brake pads within their first 1,000 miles.
The complaint also takes aim at the CX-90’s Lane-Keep Assist feature. The system is intended to provide steering assistance when a vehicle begins to move out of its lane, but plaintiffs allege it can instead apply excessive steering corrections against the driver’s input. The lawsuit claims this can make the vehicle feel unpredictable and potentially cause erratic steering if the assistance suddenly stops.
The plaintiff further alleges that Mazda was aware of concerns surrounding the brake and steering systems through service information, dealership data, and customer complaints. The complaint also claims that some owners continued experiencing problems after previous repairs and recall work.
What owners should do
Owners of 2024-2026 Mazda CX-90 models who notice persistent brake squealing, vibration, unusual braking behavior, or unexpected steering assistance should arrange an inspection with a Mazda dealer.
It is also important to keep copies of repair invoices, dealership records and details of recurring problems. Owners should check their VIN through the NHTSA recall database for any relevant safety campaigns or updates.
How Mazda owners can take back control
A vehicle that repeatedly returns to the dealership for the same problem can become a major inconvenience, particularly when the concerns involve braking or steering. If repair attempts have failed to provide a lasting solution, owners may want to consider whether they have additional legal options.
