Quick answer

Four parts are involved because they correspond to blue and red caps, which will no longer be available due to the supplier discontinuing their production. We will be transitioning to black caps over time and will retain the same part number, resulting in a mixed inventory. The new black caps are fully compatible with all existing products and will not impact on the performance or functionality of your equipment.

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.

What is NHTSA service bulletin 11023934?

Four parts are involved because they correspond to blue and red caps, which will no longer be available due to the supplier discontinuing their production.

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.
