Defect description
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.
Safety risk
THIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.
Manufacturer remedy
DEALERS 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.
Safety risk
THIS CONDITION WOULD KEEP THE REAR AXLE SERVICE BRAKES APPLIED WITHOUT ANY BRAKE PEDAL MOVEMENT BY THE DRIVER INCREASING THE RISK OF A VEHICLE ACCIDENT.
Manufacturer remedy
DEALERS 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.
THE BRACKETS THAT ATTACH THE STEERING COLUMN ASSEMBLY TO THE CAB STRUCTURE CRACKS AT THE "V" NOTCH IN THE BRACKET.
Safety risk
FAILURE OF THE BRACKET MAY CAUSE THE STEERING COLUMN ASSEMBLY TO FALL, WHICH MAY RESULT IN LOSS OF STEERING CONTROL AND AN ACCIDENT.
Manufacturer remedy
VOLVO GM WILL REPLACE THE SUSPECT BRACKETS WITH A NEWLY DESIGNED BRACKET.
