Service bulletin 04-003-26a

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

This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 04-003/26 05/29/26 DESCRIPTION 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. REPAIR PROCEDURE 1. Verify the customer concern. 2. Replace both sides of the rear brake pads with the modified ones according to the instructions in MGSS (REAR BRAKE DISC PAD REMOVAL/INSTALLATION).
