Recall campaignsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Open investigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

TRAILER HITCHES:FIFTH WHEEL ASSEMBLY

Oct 23, 2007
950 units potentially affected
The 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.
The risk: 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.
The 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 MACK TRUCKS AT 1-800-528-6586.

FUEL SYSTEM, DIESEL

Sep 5, 2007
35,649 units potentially affected
The defect: ON CERTAIN TRUCKS EQUIPPED WITH ASET AC MODEL ENGINES, THE ENGINE AS CONFIGURED WITH AN EXTERNAL EXHAUST GAS RECIRCULATION SYSTEM MAKES SERVICING THE FUEL INJECTION LINES DIFFICULT WHEN USING TRADITIONAL TOOLS. THEREFORE, IT IS POSSIBLE FOR FUEL LEAKS TO DEVELOP WHEN REMOVING AND INSTALLING THE FUEL INJECTION LINES.
The risk: A LEAK IN THE FUEL INJECTION LINE MAY SPRAY FUEL ON THE HOT SURFACES OF THE EXHAUST GAS RECIRCULATION SYSTEM, WHICH COULD RESULT IN AN ENGINE FIRE.
The remedy: DEALERS WILL REPLACE THE FUEL INJECTION LINES FREE OF CHARGE. NOTE: THIS RECALL SUPERSEDES A PREVIOUS CAMPAIGN CONDUCTED IN 2006 (PLEASE SEE 06V392).

SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE

Aug 15, 2007
21,847 units potentially affected
The defect: ON CERTAIN TRUCKS EQUIPPED WITH PARKER SINGLE CHECK VALVES (SCV) PROVIDED BY BENDIX. THE DEFECT EXISTS IN THE PARKER SCV THAT CONNECTS WITH THE SUPPLY PORT OF THE SR-7 SPRING BRAKE MODULATING VALVE.

PIECES OF THE PARKER SCV CAN BECOME LODGED INSIDE THE SR-7 SPRING BRAKE MODULATING VALVE, POTENTIALLY CAUSING EITHER LEAKAGE OUT OF THE SR-7 VALVE OR PREVENTING AIR FROM PROPERLY EXHAUSTING FROM THE SR-7 VALVE.
The risk: THIS CONDITION CAN CAUSE A DELAY IN THE APPLICATION OF THE SPRING BRAKES TO PARK THE VEHICLE AFTER THE OPERATOR PULLS THE DASH VALVE BUTTON. THESE CONDITIONS CAN OCCUR WITHOUT WARNING, LEADING TO UNINTENDED VEHICLE ROLLAWAY, BRAKE DRAG, OR IN THE CASE OF LOSS OF PRIMARY CIRCUIT, INABILITY TO MODULATE THE SPRING BRAKES.

What a recall is

Safety recall
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
Safety investigation
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
