Frequently Asked Questions - FAQ


What is a Technical Service Bulletin?

A Technical Service Bulletin (TSB) is a document that identifies an unanticipated vehicle or part issue and provides a solution. There can be more than one TSB for the same issue if different technicians or engineers have figured out different solutions. A TSB may be provided to dealerships, sent to auto repair shops, or sent out to vehicle owners, depending on the range and scope of the problem.


What is the difference between a Recall and a Technical Service Bulletin?

While a recall concerns a safety issue which must be fixed, a Technical Service Bulletin just identifies a common issue and documents a solution. The difference is that manufacturers are not required to make the repair at no cost for a problem documented in a TSB. However, the circulation of the bulletin amongst dealerships and manufacturers can help diagnose the issue and lead to faster and more efficient fixes.


Do I have to pay or will the manufacturer pay for the TSB related repairs?

Dealers and manufacturers are not required to pay for a repair indicated in a TSB since the issue is not identified as posing a safety concern. There may be repairs that a manufacturer agrees to pay for, however, particularly if the repair has the potential to cause a class-action lawsuit for the manufacturer, and these notifications evolve from a TSB into a "service campaign" or "service warranty".


How do I find out if a TSB has been issued for my vehicle or part of my vehicle?

The Technical Service Bulletin tool on this site can be used to determine if there are outstanding TSBs on your vehicle. Simply select by vehicle year, make, and model.
