Understanding Service Bulletins vs. Recalls
While this issue is currently addressed through a Technical Service Bulletin (TSB), it's important to understand how this differs from a formal safety recall:
| Service Bulletin (TSB) | Safety Recall |
|---|---|
| Addresses known issues with repair procedures | Corrects safety-related defects |
| Performed under warranty coverage | Mandated by government agencies |
| Repairs only when symptoms appear or during service visits | All affected vehicles must be repaired |
