Service bulletin Q255NAS3

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

"SITUATION: WHILE DRIVING IN WET WEATHER CONDITIONS, CONDENSATION MAY BUILD UP WITHIN THE ENGINE CHARGE AIR RADIATOR. FOLLOWING A RAPID INCREASE IN ENGINE SPEED, THIS CONDENSATION COULD BE DRAWN IN TO ONE OF THE ENGINE’S CYLINDERS, CAUSING THE ENGINE MANAGEMENT SYSTEM TO SENSE A MISFIRE. THE ENGINE IS PROGRAMMED TO REACT TO THIS MISFIRE BY INITIATING A RESTRICTED PERFORMANCE MODE TO PROTECT THE EXHAUST CATALYST. IN THIS MODE, THE DRIVER NOTICEABLY EXPERIENCES REDUCED POWER TO ACCELERATE UNTIL THE ENGINE IS SWITCHED OFF AND THEN RESTARTED. FURTHERMORE, AN ENGINE WARNING MESSAGE WILL DISPLAY IN THE INSTRUMENT CLUSTER MESSAGE CENTER AND THE ENGINE MALFUNCTION INDICATOR LAMP MAY ILLUMINATE."
