Exclamation Recall # WQC39 - ECM Reprogramming for Coolant Thermostat

I just logged into my.subaru and happened to see the following recall listed for my BRZ. Has anyone taken their car in for this update?


Service Program WQC-39
Engine Control Module Reprogramming
Vehicles Registered in the States of
CA, CT, MA, MD, ME, NJ, NY, OR, PA, RI, VT, WA

Dear Subaru Owner:

We would like to thank you for your selection of a Subaru vehicle. At Subaru, we take pride in our products and are committed to your continued satisfaction.

Subaru has developed a modification to the Engine Control Module software logic to improve the monitoring parameters within the On-Board Diagnostic (OBDll) system for the engine coolant thermostat. This correction ensures that should there be an abnormal condition (i.e., the engine coolant does not reach or maintain the proper operating temperature), the “check engine light” will illuminate. The proper illumination of the “check engine light” is needed to alert you that corrective action may be required.

This software change has no effect on fuel economy or vehicle performance
