Technical Service Bulletins, or TSBs, are recommended procedures for repairing vehicles. Not to be confused with recalls, a TSB is issued by a vehicle manufacturer when there are several occurrences of an unanticipated problem. Because certain problems may have more than one cause or there are sometimes more than one way to fix a problem, it’s somewhat common for there to be more than one TSB for the same problem.
Dealers are usually under no mandate to call in cars for which there are TSBs to do the related repairs. Nor is there an obligation to do the TSB repairs for free or at reduced charges to the owner.
