Official summary
TSB: Some 2022 model year Tacoma vehicles may exhibit a coolant leak, coolant dripping onto the ground, or high engine coolant temperature. The coolant leak may occur from the rear of the engine and drip down the transmission bell housing. Upon further inspection, coolant may be leaking from the union between the Rear Water By-Pass Joint and the No.1 Water Outlet Pipe (see Figure 1). Follow the Repair Procedure in this bulletin to address this condition.

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.
