N192278200 - Service Update. Certain vehicles may have DTC P0607 intermittently set due to an engine control module (ECM) software and calibration error. With the DTC set, the check engine light will illuminate, and the transmission will default to 3rd gear on the next key cycle. Reverse, neutral, and park remain available. The engine may rev higher as not all 10 gears will be available in forward motion. Dealers will replace the winter grill cover.
