Service bulletin 15344

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

15344 - SERVICE UPDATE. THE PURPOSE OF THIS SERVICE UPDATE IS TO PROVIDE THE CUSTOMER WITH A GOODWILL GIFT TO OFFSET OWNER INCONVENIENCE, RESTORE CONFIDENCE, AND MAINTAIN LOYALTY TO GM. THE VEHICLES INVOLVED IN THIS SERVICE UPDATE WERE ORIGINALLY INVOLVED IN RECALL 14471. WHEN THE VEHICLE WAS REPROGRAMMED FOR RECALL 14471, THE VEHICLES RECEIVED AN INCORRECT CALIBRATION. THE VEHICLES WERE RECALLED AGAIN UNDER RECALL 15100. APPROXIMATELY ONE WEEK AFTER LAUNCHING RECALL 15100, THE SOFTWARE FILES WERE ERRONEOUSLY CHANGED FROM THE REVISED SOFTWARE TO THE ORIGINAL INCORRECT SOFTWARE VERSION. VEHICLES THAT WERE SERVICED BETWEEN FEBRUARY 8, 2015, AND MARCH 10, 2015, RECEIVED THE ORIGINAL INCORRECT SOFTWARE. THESE CUSTOMERS ARE NOW BEING ASKED TO BRING THEIR VEHICLE BACK FOR THE CORRECT CALIBRATION UNDER RECALL 15259. FOR THEIR INCONVENIENCE, DEALERS ARE TO OFFER THE CUSTOMER A SELECTION OF ONE OF THE AVAILABLE GOODWILL OPTIONS LISTED IN THIS BULLETIN. BECAUSE EACH CUSTOMER HAS UNIQUE PREFERENCES, PLEASE OFFER BOTH OF THE OPTIONS FOUND IN THIS BULLETIN TO THE CUSTOMER AND ALLOW THEM TO SELECT THE ONE THAT BEST SUITS THEIR SITUATION.
