Service bulletin SGI13-20
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
"DESCRIPTION A DESIGN ISSUE HAS BEEN IDENTIFIED ON 2012-2013 MODEL YEAR RANGE ROVER EVOQUE VEHICLES WITHIN THE LISTED VIN RANGE. WHILE DRIVING IN WET WEATHER CONDITIONS, CONDENSATION MAY BUILD UP WITHIN THE ENGINE CHARGE AIR COOLER. 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. NEW COMPONENTS HAVE BEEN DESIGNED TO LIMIT CONDENSATION FROM BUILDING IN THE ENGINE’S CHARGE AIR COOLER TO PREVENT THE RESTRICTED PERFORMANCE MODE FROM INITIATING. ADDITIONALLY, UPDATED ENGINE CONTROL MODULE (ECM) SOFTWARE HAS BEEN DEVELOPED WHICH CHANGES THE THRESHOLDS NECESSARY TO INITIATE THE RESTRICTED PERFORMANCE MODE FOR THIS ISSUE. SERVICE ACTION Q255 SUPERSEDES Q237 WITH IMMEDIATE EFFECT. VEHICLES UPDATED UNDER Q237 REQUIRE THE REWORK ACTION DETAILED IN Q255."
