Technical Service Bulletin

Technical service bulletins (TSBs) are issued by the manufacturer for problems that affect the normal operation of the vehicle. Sometimes called 'secret warranties,' TSBs cover known problems and provide repair instructions for service technicians and accordingly are distributed to all of the manufacturer's dealerships. Unlike recall-related repairs, which are performed on a no-questions-asked basis, TSB repairs are made only to resolve problems that can be verified by dealer service technicians. And generally these repairs will be free of charge only if the vehicle is still under warranty. For more about TSBs, check out How Can a Technical Service Bulletin Help Me? and The Secret Warranty. To find out about any TSBs that may apply to your vehicle, please use our Maintenance Guide.
