What the National Highway Traffic Safety Administration knows about this vehicle: every recall, every consumer complaint, every defect investigation, every NCAP crash test. Sourced directly from NHTSA data feeds.
VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE AIR SUSPENSION CONTROL VALVE SUPPLY LINE WAS NOT PLUMBED THROUGH AN AIR PRESSURE PROTECTION VALVE. IN THE EVENT OF A FAILURE, THERE WOULD BE LOSS OF AIR PRESSURE IN THE 'B' SYSTEM AIR RESERVOIR THAT SUPPLIES AIR PRESSURE FOR THE FRONT STEER AXLE BRAKES.
RiskTHIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.
FixDEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.
THE TRACTION SOLENOID EXHAUST CAN BE OBSTRUCTED DUE TO INADEQUATE DRAINAGE AND A BUILD-UP OF ROAD CONTAMINATION BETWEEN THE MOUNTING BRACKET AND THE SOLENOID HOUSING. THE OBSTRUCTED EXHAUST PREVENTS THE RELAY VALVE CONTROL AIR PRESSURE FROM VENTING AFTER A DIFFERENTIAL BRAKING TRACTION EVENT.
RiskTHIS CONDITION WOULD KEEP THE REAR AXLE SERVICE BRAKES APPLIED WITHOUT ANY BRAKE PEDAL MOVEMENT BY THE DRIVER INCREASING THE RISK OF A VEHICLE ACCIDENT.
FixDEALERS WILL REMOVE THE SUSPECT VALVE AND INSTALL A NEW VALVE THAT HAS A MODIFIED SOLENOID HOUSING WHICH WILL ALLOW FOR SUFFICIENT DRAINAGE AND A NEW VALVE MOUNTING BRACKET WITH INCREASED HEIGHT TO REDUCE ENTRY OF CONTAMINATION.
AIR SYSTEM BLOCKAGE IN THE AIR DRYER OCCURS DEGRADING THE MOISTURE REMOVING CAPABILITIES OF THE DRYER WHEN THE VEHICLE IS OPERATED IN A COLD ENVIRONMENT AND MOISTURE ACCUMULATES AND FREEZES IN THE AIR DRYER OR IN THE LINE BETWEEN THE DRYER AND THE AIR SYSTEM RESERVOIR. THE AIR DRYER CAN BECOME OVERPRESSURIZED CAUSING THE AIR DRYER CARTRIDGE TO SEPARATE FROM THE MOUNTING BASE.
RiskIF THE AIR DRYER SEPARATES FROM THE BASE, THE CARTRIDGECAN SEPARATE SUFFICIENTLY ENOUGH TO CAUSE PERSONAL INJURY OR PROPERTY DAMAGE.
FixDEALERS WILL EQUIP AIR SYSTEMS WITH A PRESSURE RELIEF VALVE TO BE LOCATED BETWEEN THE COMPRESSOR AND THE AIR DRYER. THIS PRESSURE RELIEF VALVE IS INTENDED TO VENT IF EXCESSIVE PRESSURE DEVELOPS IN THE AIR DRYER.
THE BRACKETS THAT ATTACH THE STEERING COLUMN ASSEMBLY TO THE CAB STRUCTURE CRACKS AT THE "V" NOTCH IN THE BRACKET.
RiskFAILURE OF THE BRACKET MAY CAUSE THE STEERING COLUMN ASSEMBLY TO FALL, WHICH MAY RESULT IN LOSS OF STEERING CONTROL AND AN ACCIDENT.
FixVOLVO GM WILL REPLACE THE SUSPECT BRACKETS WITH A NEWLY DESIGNED BRACKET.
