Mazda technical service bulletin 04-003-26 for 2024-2026 Mazda CX-90 and 2024-2026 Mazda CX-90 Plug-In Hybrid.

Bulletin number
04-003-26
Component
Service brakes
Summary
Some vehicles may exhibit a squeaking noise from the rear brake during deceleration, and the noise is particularly noticeable during braking when the brakes are cold. This is caused by the brake pad(s) having difficulty contacting evenly with the rotor surface during light braking due to wear and/or deformation of the brake pad(s). To eliminate this concern, the shape of the rear brake pads will be modified. Replace both sides of the rear brake pads with the modified ones according to the instructions in MGSS (REAR BRAKE DISC PAD REMOVAL/INSTALLATION).

Owners of these vehicles have filed 28 complaints in the brakes category.
