Quick answer

Product Link models PL121/321s will stop sending data after April 6th, 2019. Date codes will appear as if coming from the past so the customer interface (UI) will not recognize those back dated messages and no data will appear in the UI.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.

Frequently asked questions

What is NHTSA service bulletin 10158770?

Product Link models PL121/321s will stop sending data after April 6th, 2019. Date codes will appear as if coming from the past so the customer interface (UI) will not recognize those back dated messages and no data will appear in the UI.

Is a service bulletin the same as a recall?

No. A recall is a safety campaign with a required remedy for affected VINs. A service bulletin or manufacturer communication usually describes diagnostic, repair, software, warranty or service information.

How should a used-car buyer use this bulletin?

Use it as a research signal. Compare it with recalls, owner complaints, service records, a VIN report and an independent inspection before buying.

Check the exact VIN before you buy

Model-level pages show public safety patterns. A full VIN report helps confirm the exact vehicle, decoded specs, recall applicability and buyer checks.
