Technical Service Bulletins (TSBs) are recommended repair procedures issued by a manufacturer alerting dealers to potential non-safety related defects affecting a vehicle’s performance or life. They help repair technicians diagnose and repair a problem, specifying tools, techniques, and required parts. They can also alert dealers to issues, such as changes in tire pressure or lubricants, repair procedures, and maintenance requirements. TSBs are not recalls and do not entitle customers to free repairs, but some bulletins indicate when the manufacturer is extending warranty coverage for a specific problem. Knowing about TSBs issued for your vehicle can help you save money by alerting you of problems with a car you own or plan to buy. In some cases, they also can expose an early hint of a potential safety problem or the risk of an expensive future problem. Depending on the issue, some bulletins may be difficult to understand for anyone unfamiliar with car repair.
