Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2006-2009 model year Buick Lucerne; Cadillac DTS;
HUMMER H2; 2008-2009 model year Buick Enclave; Cadillac CTS; 2007-2009 model year Cadillac Escalade, Escalade ESV, Escalade EXT;
Chevrolet Avalanche, Silverado, Suburban, Tahoe; GMC Acadia, Sierra, Yukon, Yukon XL; Saturn OUTLOOK; and 2009 model year Chevrolet
Traverse vehicles equipped with a heated washer fluid system (RPO XA7/CHW). A recall was implemented on some vehicles in 2008 to add a fuse to
the HWFS control circuit harness to address the potential consequences of a printed circuit board 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. Their significance varies from minor distortion to considerable melting of the plastic around the HWFS fluid chamber. In
some circumstances, it is possible for the heated washer module to cause a fire.
Correction
Dealers/retailers are to permanently disable and remove the heated washer fluid system and compensate the customer for the loss of the feature.
