Official summary
When diagnosing a customer concern of fuel gauge not reading full after fueling, start by checking for the presence of a cover over the fuel tank vent as shown in the picture below. Vent is located on filler neck and can be inspected by removing fuel door assembly. If cover is found over vent, inspect for damage to fuel tank and replace tank if needed. Ensure cover is not present on replacement fuel tank. If fuel tank is not damaged, remove cover over fuel tank vent and retest for customer concern. If cover is not present over vent, continue with normal diagnosis.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
