Service bulletin 02-002-26

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.

NHTSA's summary

Some vehicles may exhibit a creaking or squeaking noise from the lower control arm at the front suspension when traveling over a bump while turning at low-speed. A stick-slip phenomenon may occur between the stopper rubber (2) and the bracket (3) in the front lower arm (rear) (1). To eliminate this concern: Grease has been applied to the stopper rubber. Dust covers have been installed to the lower arm. The mounting hole size of the lower arm bracket has been modified.

02-001-262026-05-03. Service bulletin. 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-051-252025-12-05. Service bulletin. 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.
02-002-25a2025-10-03. Service bulletin. Some vehicles may experience a knocking noise from the front suspension when driving on a rough road or traveling over bumps. This noise is caused by a gap between the front strut bump stopper and the mounting rubber that is pushed up when roads are bumpy. To eliminate this concern, the outer diameter of the bump stopper has been modified to prevent the knocking sound during driving on a rough road or traveling over bumps.

Mazda vehicles sold in Canada and Mexico are also affected by MSP62 and must be repaired if presented to your dealership.MAZDA SALES AND SERVICE TEAMS - ACTION ITEM: There are approximately 20 vehicles in stock at U.S. Mazda dealers which must be repaired prior to delivery. All Mazda dealers must quarantine any affected new, used or CPO in-stock vehicles until the repair is completed. The affected dealer inventory list was provided to each District Service Manager with the notification of this dealer email. Once completed, the car can be delivered, and the Warranty claim can be submitted later without penalty since the car has been repaired. Outline of Concern: Some vehicles may exhibit a creaking or squeaking noise from the lower arm at the front suspension when traveling over a bump and while turning at low-speed. Causal factor: A stick-slip phenomenon may occur between the stopper rubber and the bracket in the front lower arm. There are 18,127 vehicles affected by this campaign in the U.S. and U.S. Territories.Important Note: Certain vehicles repaired under TSB# 02-002/24 are excluded from this MSP but others may be included. If the MSP62 is Open in eMDCS Warranty Inquiry, please perform the repair.
