Service bulletin C2046A

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

This Campaign is being issued to address turbo actuator corrosion / water intrusion resulting in an active fault code 1894 in certain chassis. This campaign authorizes certified locations to apply Loctite 290 and Permatex Silicone around the turbo actuator electrical connector and add insulation wrap to the OEM air conditioning line to prevent corrosion and water intrusion in the turbo actuator. This is an update to a previous communication.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
