1996 Volvo WCA

CERTAIN HEAVY DUTY CLASS 8 TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT." THE TWO TAIL LAMPS, BACK-UP LAMP,AND LICENSE TAG LAMP WERE MOUNTED ON INSUFFICIENTLY RIGID MOUNTS.

RiskIT MAY NOT ALLOW THE DRIVER OF A REARWARD APPROACHING VEHICLE TO HAVE FULL VIEW OF THE LAMPS.

FixDEALERS WILL ATTACH THE TWO TAIL LAMPS, BACK-UP LAMP, AND THE LICENSE TAP LAMP ON STIFFER BRACKETS. OWNER NOTIFICATION BEGAN OCTOBER 31, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT VOLVO TRUCKS AT 1-800-528-6586.

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.

WARNING LABELS IDENTIFYING THE CLIMBING SEQUENCE AND PROCESS WERE OMITTED.

RiskPERSONS NOT USING THE SEQUENCE AND PROCESS DURING CAB ENTRY OR EXIT OR WHEN USING THE OPTIONAL BACK OF CAB ACCESS MAY SLIP AND/OR FALL CAUSING PERSONAL INJURY.

FixVOLVO HEAVY TRUCK WILL BE PROVIDING WARNING LABELS TO BE INSTALLED BY OWNERS ON THEIR TRUCKS.

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.

VEHICLE DESCRIPTION: HEAVY DUTY CLASS 8 VEHICLES BUILT WITH A VOLVO 5.7 (12,500 LBS) FRONT STEERING AXLE. DUE TO HYDROGEN EMBRITTLEMENT, THE FRONT STEERING AXLE KING PINS COULD HAVE BROKEN DURING ASSEMBLY. CONTINUED OPERATION OF A VEHICLE WITH A BROKEN KING PIN COULD ALLOW THE PIN TO WORK LOOSE.

RiskTHIS CONDITION CAN CAUSE ERRATIC STEERING RESULTING IN LOSS OF STEERING CONTROL INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.

FixDEALERS WILL INSPECT THE VEHICLES FOR A BROKEN KING PIN AND REPLACE THE KING PINS IF BROKEN.
