Official summary
Some 2022 – 2024 model year Tundra Hybrid and 2023 – 2024 model year Sequoia Hybrid vehicles may exhibit a condition where the vehicle starts in second gear from a stop, and does not allow a manual shift to first gear (S1) without first switching to 4WD or driving over 15 mph. The Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM) logic has been modified to address these conditions.
Vehicles covered
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.
