Mazda CX-90 owners filed a class action lawsuit against the automaker due to severe brake wear

Car owners claim that dealers cannot fix problems even after repeated calls, Autoblog reports.

One of the plaintiffs, James R. Burnell, claims that cars from 2024 to 2026 suffer from constant brake squealing and incorrect operation of the Lane-Keep Assist system. At the same time, Mazda dealers, according to him, were unable to diagnose or fix the problems.

The plaintiff’s story began with the purchase of a 2024 CX-90, which he returned to the dealer due to problems with the lane keeping system. The second car of the same year also began to cause inconvenience – this time there was squealing brakes.

Over the course of two years, the owner repeatedly contacted dealers, but the technicians either considered the car’s behavior normal or could not identify the cause. After the car was subject to a recall campaign, the dealer diagnosed “scratched brake discs and pads.” In September 2024, the technician replaced the entire brake system. However, the noise returned almost immediately.

The lawsuit emphasizes that such repeated failures indicate a design or manufacturing defect rather than normal wear and tear. In addition, it is alleged that Mazda knew about similar problems on other models but did not fix them.

The second serious complaint concerns the operation of Lane-Keep Assist. According to the plaintiff, the system, instead of gently correcting the car’s course, can abruptly return the car to the lane. Some such commands are contrary to the driver’s intentions.
