Official summary
Region Letter: On certain vehicles equipped with a 2GR-FE (V6) engine, the rubber portion of the oil supply hose for the VVT-I actuator may degrade over time. This condition may cause oil to leak from the VVT-I oil hose producing abnormal engine noise and the oil pressure light to illuminate. The following vital information is provided to inform you and your staff of the dealer and owner notification phase of the campaign and your degree of involvement. Additional information may be found in the attached Lexus Q&A and customer notification letter.
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.
