Important Warnings

This manufacturer communication, identified by NHTSA ID 10212526, is a technical service bulletin (TSB). Unlike a recall, which mandates a free repair for a safety defect, a TSB provides guidance to dealerships on how to diagnose and repair common issues. While safety-related, whether the repair is covered under warranty depends on your vehicle's warranty status and the specific nature of the fault. Always confirm coverage with your dealer before any work is performed.
