Looking up by VIN? NHTSA publishes TSBs by model and year, not by VIN — find your
model below and open your year. Your VIN is the key for recalls, and for whether a service campaign or warranty extension covers
your specific vehicle: take the bulletin's document ID to a dealer and ask.
A technical service bulletin is the manufacturer telling its dealers how to diagnose and repair a pattern it has seen — a known noise, leak, software fault, or part that wears early. Manufacturers must file these communications with NHTSA, which publishes them.
Can I look up TSBs by VIN?
Not directly — NHTSA publishes TSBs by make, model, and model year, not by VIN. Look up your model year here, then match bulletins to your vehicle. The VIN matters for recalls (check it at nhtsa.gov/recalls) and for whether a service campaign or warranty extension covers your specific vehicle.
Are TSB repairs free?
Not automatically. You pay unless the vehicle is under warranty or the bulletin is a warranty extension or service campaign that covers your VIN. Recall repairs are always free.
What is the difference between a TSB and a recall?
A recall is a safety defect the manufacturer must fix for free on every affected vehicle. A TSB is repair guidance for a known pattern that has not been declared a safety defect — useful for diagnosis and negotiation, but it obligates nobody.
