Official summary
Some vehicles may exhibit a lack of engine power / intake air leak noise from the engine compartment. Hose clamps A and/or B for the air hose (C) for the turbocharger air outlet pipe (D) may be loose due to insufficient tightening. The tightening torque of the hose clamps has been increased to eliminate this concern.
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.
