Official summary
TT: Special Service Campaign 21TC05 applies to the following condition: The fuel gauge needle and the ?distance to empty? estimated in the vehicle display accurately indicate the approximate amount of remaining fuel in the fuel tank. However, some drivers are continuing to drive after the low fuel light illuminates, causing them to potentially run out of fuel and be inconvenienced. NOTE: Highlander HV fuel gauge issues, such as, fuel gauge not reading full or tank capacity does not meet expectations DO NOT apply to 21TC05.

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.
