Technical Service Bulletin (TSB)
A technical service bulletin is a manufacturer document that tells workshops how to fix a known problem.
What is Technical Service Bulletin (TSB)?
TSBs are not recalls and repairs are not automatically free. They cover noises, software updates and procedures. Workshops check TSBs before diagnosis. TSBs often describe updated parts, revised software or a new repair method, and list affected model years and VIN ranges. In the US, NHTSA publishes many manufacturer communications.
How it works
The manufacturer publishes the bulletin to dealers and sometimes regulators.
Why it matters for your car
A matching TSB can save diagnostic time. Some TSB repairs may be covered under warranty.
