What is a TSB? (Technical Service Bulletins)
July 16, 2018
If your vehicle had something in its design or production that the manufacturer had figured out had an unanticipated problem, you'd want to know about it. And you'd want it fixed. There is something that can help drivers with just such a scenario. It's called a Technical Service Bulletin, or TSB.
Here's what a TSB is. Vehicle design and manufacturing is a very complex process. Aftrer every vehicle is introduced, the more units there are on the road, the more likely weaknesses in parts or design will start to show up.
Automakers gather data on the issues and how best to fix them. Then they send out TSBs (usually in the first year of the new model) so technicians will know to look for those problems and what to do about them. There may be more than one cause of a problem with a vehicle so there may be more than one TSB for an issue.
A TSB can be issued for anything from failing water pumps to strange noises to smelly headliners. A TSB and a recall aren't the same thing. A recall is issued if there's a problem that could cause harm to people or if it creates illegal emissions. The manufacturer pays for a safety defect to be fixed, and the repair is usually performed at a dealership.
But when a Technical Service Bulletin is issued, it's because there's a pattern of some system not working the way it should. If a vehicle is under warranty and the problem can be diagnosed in a specific vehicle, the manufacturer will probably pay for the repair. But there may be limits. Take one case with certain models of a minivan. Some wheel bearings were failing prematurely, so the manufacturer extended the warranty on them to 5 years or 90,000 miles/145,000 km. After that, the owner bore the cost. In some cases, a manufacturer will reimburse owners for a repair already done at an independent service facility.
You may have a vehicle that is no longer covered by a warranty but a TSB has been issued for a certain problem. In that case, any service facility can perform the service. At Charlie's Fast Lube Anna, your service advisor will have access to TSBs that have been issued for your vehicle's year and model. They will help the technician diagnose it if your vehicle has the issue. The TSB will also have advice for the best repair procedure to get your vehicle working the way it should.
