Critical riskHealth Canada

An official Health Canada notice concerns Buick - General motors. On certain vehicles equipped with a Heated Washer Fluid System (HWFS), a short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. A repair was implemented in a recall in 2008, however, there have been new reports of thermal incidents on heated washer fluid system modules after this improvement was installed. This situation may cause some minor distortion, but also could lead to melting of the plastic around the heated washer fluid system, or cause a fire. Correction: Dealers will permanently disable and remove the heated washer fluid module. An updated page will be provided and inserted in the Owner Manual to document the removal of the feature.
