Service bulletins for the 2026 Mazda CX-90

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

143 on file from NHTSA, as of 2026-10-19.

02-001-262026-05-03. Service bulletin. SUSPENSION. Some customers may complain that an abnormal noise is heard from the front suspension when driving on rough road surfaces or when passing over speed bumps. This is caused by insufficient heat resistance of the bushing material under specific operating conditions, resulting in cracking and fluid leakage in the front lower arm bushing. To eliminate this concern: The bushing material has been changed to a heat-resistant material. The bushing shape has been modified to reduce deformation. The damping characteristics of the front lower arm bushing have been modified. REPAIR PROCEDURE If noise is detected, replace the front lower arm (rear side) according to the instructions in MGSS.
SA-057-252026-01-03. Service bulletin. SUSPENSION; UNKNOWN OR OTHER; SERVICE BRAKES. A technician may report that DTC U0415:68 - VCM (Vehicle Control Module) cannot be cleared after replacing the DSC (Dynamic Stability Control) module.
SA-051-252025-12-05. Service bulletin. STEERING; SUSPENSION; POWER TRAIN; WHEELS. Noise, Vibration, and Harshness (NVH) Diagnostic Guidelines Diagnostic Guidelines When diagnosing NVH concerns, it is essential to first classify the issue into one of three primary categories: Noise, Vibration, or Harshness. Many customer complaints may involve overlapping symptoms, such as both noise and vibration, so identifying the dominant characteristic is critical. Once the primary symptom is determined, follow the appropriate diagnostic path. For example, if a concern includes both noise and vibration but is related to vehicle speed, the vibration diagnostic path should be followed. When considering component replacement during the diagnostic process, it is best practice to start with the lowest cost or most accessible part unless diagnostic evidence clearly identifies a more expensive or complex component as the root cause. This approach helps minimize repair costs and avoids unnecessary part replacements. For example, a growling or bearing whine noise may be mistakenly attributed to internal components in the differential, transfer unit, or transmission, when the actual source is a wheel bearing. Misdiagnosis like this can lead to unnecessary repairs, added time and cost. To help prevent this, always follow the guidelines in the repair procedure.
