2007 Volvo Vnl problems

Defect

Volvo Trucks North America (Volvo) is recalling certain model year 2007-2014 VAH, VHD, VNL, VNM, and VT models. The affected vehicles were built without a redundant clutch disengagement switch. Without a redundant switch, a loss of signal from the brake air pressure switch can prevent the clutch from automatically disengaging when the brake is applied.

Consequence

Without a signal to disengage the clutch when the brakes are applied, the distance required to stop the truck may lengthen, increasing the risk of a crash.

Remedy

Volvo Trucks will notify owners and dealers will inspect and repair the vehicles if necessary. The recall began on August 26, 2013. Volvo's recall number is RVXX1303. Owners may contact Volvo at 1-336-393-2000.

Consequence

IF THIS HAPPENS A SHORT CIRCUIT MAY OCCUR, WHICH OVER TIME COULD POSSIBLY LEAD TO A VEHICLE FIRE.

Remedy

Defect

VOLVO TRUCKS IS RECALLING 366 MY 2006-2009 VNL TRUCKS EQUIPPED WITH SUPER SINGLE TIRES, BENDIX BRAKE CAM TUBES, AND VOLVO AIR SUSPENSION. THE VIBRATION FREQUENCY FROM THE SUSPENSION WITH SUPER SINGLE TIRES MAY RESULT IN A FATIGUE CRACK OF THE MOUNTING BRACKETS FOR THE BRAKE CAM TUBE.

Consequence

IF LEFT UNTREATED, THE CRACK CAN PROPAGATE AND CAUSE FAILURE OF THE BRAKE CAM TUBE SUPPORT BRACKET(S), WHICH CAN RESULT IN LOSS OF BRAKES AT THE CORRESPONDING WHEEL END INCREASING THE RISK OF A CRASH.

Remedy

Defect

ON CERTAIN HEAVY DUTY TRUCKS, THE CIRCUIT PROTECTION (I.E. AUTOMATIC CIRCUIT BREAKERS) USED TO PROTECT THE VEHICLE LIGHTING SYSTEM MAY NOT PROVIDE ADEQUATE PROTECTION.

Consequence

Remedy

DEALERS WILL REPLACE THE CIRCUIT BREAKERS WITH FUSES. THE RECALL BEGAN ON FEBRUARY 25, 2008. OWNERS MAY CONTACT VOLVO TRUCKS AT 1-800-528-6586.

Defect

ON CERTAIN TRUCKS EQUIPPED WITH A SAF HOLLAND SIMPLEX FIFTH WHEEL, THE LEVER ARM PIVOT BOLT MAY HAVE BEEN OVER TIGHTENED. AN OVER TIGHTENED PIVOT BOLT CAN DISTORT THE PIVOT BOLT SPACER SLEEVE, WHICH MAY PREVENT THE FIFTH WHEEL LATCH JAW FROM CLOSING AND LATCHING SECURELY AROUND THE TRAILER KING PIN.

Consequence

THERE IS A POSSIBILITY THAT THE PIVOT BOLT CAN BECOME LOOSE WITHOUT THE DRIVER'S KNOWLEDGE. WHEN THIS OCCURS, THE DRIVER COULD DRIVE AWAY AND THE TRAILER COULD BECOME DISENGAGED, INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL REPLACE THE PIVOT BOLT AND SLEEVE WITH A HEX HEAD SHOULDER BOLT AND WASHER FREE OF CHARGE. THE RECALL BEGAN ON JANUARY 28, 2008. OWNERS MAY CONTACT VOLVO TRUCKS AT 1-800-528-6586.

Defect

ON CERTAIN TRUCKS, AN UNPROTECTED LEAD IN THE THERMOSWITCH OF THE HEATER MAY MAKE CONTACT WITH ANOTHER POST POSSIBLY CREATING A SHORT CIRCUIT, WHICH CAN RESULT IN CONTINUOUS OPERATION OF THE HEATING ELEMENT.

Consequence

IF THE CONDITION EXISTS AND THE KEY IS LEFT ON WITHOUT FUEL IN THE FILTER, THE HEATING ELEMENT MAY HEAT TO A POINT WHERE A FLAME BECOMES PRESENT AT THE TIP OF THE ELEMENT WHICH COULD RESULT IN A VEHICLE FIRE.

Remedy

DEALERS WILL INSPECT THE THERMOSWITCH AND WILL REPLACE IT IF NECESSARY. THE RECALL BEGAN ON SEPTEMBER 10, 2007. OWNERS MAY CONTACT VOLVO TRUCKS AT 1-800-528-6586.

Defect

ON CERTAIN TRUCKS, THE NUT USED TO RETAIN THE STEERING SHAFT MAY OR MAY NOT BE A LOCK NUT THAT HAS THE LOCKING FEATURE. A LOCK NUT IS REQUIRED TO PROVIDE ADDITIONAL RESISTANCE TO ENSURE THAT THE NUT DOES NOT COME LOOSE.

Consequence

IF THE NUT WERE TO COME LOOSE, THE STEERING SHAFT COULD POTENTIALLY SEPARATE RESULTING IN LOSS OF STEERING CONTROL WHICH COULD CAUSE A CRASH.

Remedy

DEALERS WILL REPLACE THE STEERING SHAFT PINCH BOLTS AND LOCKNUTS FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 24, 2007. OWNERS MAY CONTACT VOLVO TRUCKS AT 1-800-528-6586.

Remedy

DEALERS WILL REPAIR AND INSPECT THE AXLES AND REPLACE THEM FREE OF CHARGE. THE RECALL BEGAN ON APRIL 9, 2007. OWNERS MAY CONTACT VOLVO TRUCKS AT 1-800-528-6586.

Defect

ON CERTAIN TRUCKS EQUIPPED WITH ARVINMERITOR RPL20 HIGH ANGLE INTERAXLE DRIVESHAFTS, AN IMPROPER SEATED OR MISSING SNAP RING CAN RESULT IN THE BEARING CUP TO SEPARATE FROM THE SLIP YOKE SUB-ASSEMBLY.
