Official summary
Service bulletin - The MIL comes on with DTC P0035 (turbocharger bypass control solenoid valve circuit high) and the message REV Match System Problem / Emissions System Problem on the MID. Due to heat and the natural frequency of the harness, the coupler wire oscillates, causing an open circuit to the turbocharger bypass control solenoid valve.

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.
