Service bulletin A18-044

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
