GM IS RECALLING CERTAIN MODEL YEAR 2006-2009 BUICK, LUCERNE; CADILLAC DTS; HUMMER H2; MODEL YEAR 2008-2009 BUICK ENCLAVE; CADILLAC CTS; MODEL YEAR 2007-2009 CADILLAC ESCALADE, ESCALADE ESV, ESCALADE EXT; CHEVROLET AVALANCHE, SILVERADO, SUBURBAN, TAHOE; GMC ACADIA, SIERRA, YUKON, YUKON XL; SATURN OUTLOOK; AND MODEL YEAR 2009 CHEVROLET TRAVERSE VEHICLES EQUIPPED WITH A HEATED WASHER FLUID SYSTEM (HWFS). A RECALL WAS IMPLEMENTED IN 2008 TO ADD A FUSE TO THE CONTROL CIRCUIT HARNESS TO ADDRESS THE POTENTIAL CONSEQUENCES OF A PRINTED CIRCUIT BOARD (PCB) ELECTRICAL SHORT. HOWEVER, THERE HAVE BEEN NEW REPORTS OF THERMAL INCIDENTS ON HWFS MODULES AFTER THIS IMPROVEMENT WAS INSTALLED. THESE INCIDENTS RESULTED FROM A NEW FAILURE MODE ATTRIBUTED TO THE DEVICE'S THERMAL PROTECTION FEATURE. THE SIGNIFICANCE VARIES FROM MINOR DISTORTION TO CONSIDERABLE MELTING OF THE PLASTIC AROUND THE HWFS FLUID CHAMBER.
