Engine And Engine Cooling › Cooling System › Fan Vehicle Recalls

General Motors LLC (GM) is recalling certain model year 2010-2014 Chevrolet Tahoe Police Pursuit vehicles manufactured August 24, 2009, to December 1, 2013. The affected vehicles, equipped with special equipment options for police or government service, may experience corrosion of the under-hood cooling fan assembly due to fluid intrusion, which may result in an electrical short circuit.

This recall involves aftermarket parts sold by Valeo. Valeo is recalling certain engine cooling fans, part numbers 696121, 696273, and 696275, used as service replacement parts for model year 2008-2011 BMW 1-Series, 2006-2011 BMW 3-Series, 2000-2009 BMW 5-Series, 2004-2005 BMW 6-Series, and 2006-2007 BMW 7-Series vehicles. A metal-oxide semiconductor may overheat due to insufficient screwing of the semiconductor on the aluminum heat sink. This primary failure could cause adjacent components on the fan assembly motor circuit board to overheat and short.

VOLVO IS RECALLING 17,614 MY 2008-2009 S80, V70, AND XC70 VEHICLES. THE ENGINE COOLING FAN MAY STOP WORKING DUE TO A SOFTWARE PROGRAMMING ERROR IN THE FAN CONTROL MODULE (FCM). DEPENDING ON DRIVING CONDITIONS, THE CUSTOMER MAY EXPERIENCE REDUCED AIR CONDITIONING PERFORMANCE, AND/OR RAPID INCREASE IN ENGINE COOLANT TEMPERATURE.

ON CERTAIN VEHICLES, THE HEAT GENERATED BY THE ENGINE CAUSES REPEATED BENDING DEFORMATION OF THE POLYPROPYLENE COOLING FAN INCLUDING ITS RETAINING RING, WHICH STRESSES THE POLYPROPYLENE THEREBY INITIATING CRACKING OF THE BLADES. THE CENTRIFUGAL FORCES GENERATED BY THE ROTATION OF THE BLADES CAN CAUSE THE CRACKS TO PROPAGATE UNTIL COMPLETE SEPARATION OCCURS.

ON CERTAIN SPORT UTILITY VEHICLES, THE PLASTIC BLADES OF THE ELECTRIC MOTOR DRIVEN COOLING FAN MAY SEPARATE AND PENETRATE THE SHROUD.

ON CERTAIN PASSENGER AND SPORT UTILITY VEHICLES, UNDER CERTAIN OPERATING CONDITIONS, SOME ELECTRIC COOLING FANS MAY OVERHEAT POTENTIALLY CAUSING HEAT DAMAGE AND, IN RARE INSTANCES, A FIRE IN THE ENGINE COMPARTMENT.

ON CERTAIN PASSENGER VEHICLES, THE ENGINE AUXILIARY/COOLING FAN OPERATION, INCLUDING VARIABLE SPEED, IS ELECTRONICALLY CONTROLLED. FAILURE OF THE FAN MOTOR CAN CAUSE THE ELECTRICAL CIRCUITRY OF THE FAN CONTROL UNIT TO OVERLOAD AND FAIL, CAUSING THE FAN TO STOP OPERATING.

VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE ENGINE AUXILIARY/COOLING FAN OPERATION, INCLUDING VARIABLE SPEED, IS ELECTRONICALLY CONTROLLED. FAILURE OF THE FAN MOTOR CAN CAUSE THE ELECTRICAL CIRCUITRY OF THE FAN CONTROL UNIT TO OVERLOAD AND FAIL, CAUSING THE FAN TO STOP OPERATING.
