TSB lookup
Technical service bulletins are the factory's own known-issues list — the fixes dealers get told about and owners usually don't. Searching them normally means a paid subscription. Here it's free.
What a TSB is — and isn't
When a manufacturer sees the same complaint often enough — a shudder, a leak, a warning light with a known cause — it writes a bulletin telling its dealers what the fix is. That's a TSB. It's not a recall: nothing is mandated, nobody notifies you, and the repair isn't automatically free. But walking in already knowing "there's a bulletin for exactly this" changes the conversation at the service counter.
What this search covers
This searches the manufacturer-communications index NHTSA maintains — more than 175,000 bulletins — which we host ourselves and keep refreshed. You get each bulletin's number, the affected system, its date, and the summary. The full documents live with NHTSA and your dealer; the number is what you bring to the counter.
An empty result means nothing is filed under that exact year, make, and model — it is not evidence the vehicle has no known issues. Try the base model name without trim words ("F-150", not "F-150 XLT").
Got a check-engine light too?
A bulletin tells you what's commonly wrong. Your car's own data tells you what's actually wrong. The Fixiom app reads codes, freeze frames, and live sensors free forever — and its AI folds these same bulletins into a diagnosis of your specific fault.
This tool lives inside the Fixiom app too
The scan tool is free forever — read and clear codes, live data, freeze frames, emissions checks, the battery test, and the trip computer. Credits only cover the AI reasoning on top. The adapter side needs a Bluetooth LE OBD2 adapter (about $20–30) — see the adapter guide.
