Exterior lighting: switch

08V68800034,269 vehicles affected

The problem
Mack is recalling 34,269 my 1999-2005 cx and my 2004-2008 cxn trucks. The headlight switch may prematurely fail resulting in inoperative or intermittent headlights.
The risk
The head lights may not operate properly which could result in intermittent or no headlight function. This could impair a driver's visibility, increasing the risk of a crash.
The fix
Dealers will replace the headlight switch. The recall began on february 27, 2009. Owners may contact mack at 1-800-528-6586.

Fuel system

07V40100035,649 vehicles affected

The problem
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 fix
Dealers will replace the fuel injection lines free of charge. Note: this recall supersedes a previous campaign conducted in 2006 (please see 06v392). The recall began on september 11, 2007, with subsequent mailings every six weeks until april 2008. Owners may contact mack at 800-528-6586.

Fuel system

06V39200040,204 vehicles affected

The problem
On certain trucks, a leak in the aset ac fuel injection line may spray fuel on the exhaust gas recirculation pipes that carry hot exhaust gases .
The risk
THIS COULD POTENTIALLY RESULT IN AN ENGINE FIRE.
The fix
Mack has issued a stop work on this campaign under further notice (2-22-2007). The remedy does not adequately address the issue on all vehicles. Mack will re-release the recall in the near future. (Please see nhtsa no. 07V159/mack recall no. Sco323 for vehicles that have had this repair already performed.) This recall has been superseded (please see 07v401/sc0324).

Service brakes

05V21300056 vehicles affected

The problem
On certain heavy duty class 8 trucks, there is a slack on the brake assembly's adjuster and it is interfering with the axle housing.
The risk
This interference leads to a reduction in braking capabilities on the right side of the vehicle as the brake "shoes" become worn, increasing the risk of a crash.
The fix
The rear brake assemblies were replaced. All vehicles have been repaired.

Fuel system: hoses, lines / piping, and fittings

05V01500013,173 vehicles affected

The problem
On certain heavy duty class 8 diesel trucks equipped with aset ac engines, the location of the fuel inlet hose may result in overheating or abrasion of the hose, which may lead to a premature failure.
The risk
If the hose fails, fuel can be sprayed on the exhaust manifold, which could potentially lead to an engine compartment fire.
The fix
Dealers will repair and replace the fuel inlet hose free of charge. The recall began on february 14, 2005. Due to some quality and supply issues with parts to support this safety recall, owners may have been informed during april 2005,that the safety recall was on hold. These issues have now been resolved. For owners who have not had their vehicle(s) repaired, contact a mack parts and service center immediately to schedule an appointment to have your vehicle(s) repaired. Owners may contact mack trucks at 610-709-2131.

Steering

04V4560004,959 vehicles affected

The problem
On certain truck chassis, the steering gear mounting bolts were made of inconsistent bolt material, which has led to bolt failures. This inconsistent bolt material condition could result in a failure of a steering gear mounting bolts. The steering gear is mounted to the vehicle's frame with three bolts.
The risk
Failure of two of the three bolts could result in the loss of steering, which could result in loss of vehicle control and crash without warning.
The fix
Dealers will inspect vehicles. New steering gear mounting bolts will be installed. The recall began october 2004. Owners should contact mack at 1-610-709-3337.

Steering: arm

03V522000148 vehicles affected

The problem
On certain chassis equipped with dana steering axle assemblies. These axles are built with an integral knuckle and steering arm. The steering arm could have longitudinal cracks.
The risk
The ball stud could become loose, causing loss of steering control which could result in a crash.
The fix
Dealers will inspect the integral knuckle and steer arm and replace if necessary. Owner notification began on january 16, 2004. 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 mack at 1-610-709-3337.

Service brakes: check valve

03V2530001,232 vehicles affected

The problem
Certain heavy duty vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 121, "Air brake systems." Improper seating of the check valve retainer in the brass fitting housing has occurred. It is possible for the air brake system pressure to push the check valve internal parts into the primary system reservoir and a vehicle operator would not know that this has happened.
The risk
In this condition, the vehicle would not meet the emergency requirements of the standard.
The fix
Dealers will replace the check valve. Owner notification began november 26, 2003. Owners should contact mack at 1-610-709-3337.

Trailer hitches: fifth wheel assembly

03V21900065 vehicles affected

The problem
On certain heavy duty trucks equipped with jost international jsk 37u series fifth wheels, a fatigue crack can develop in the bracket pin weld under certain loading conditions.
The risk
If left undetected or corrected it could lead to the separation of the fifth wheel top plate from its mounting structure, possibly resulting in a crash.
The fix
Dealers will replace the bracket pins and repair instructions free of charge. 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 jost international at 616-846-7700 or by email to [email protected] or mack at 610-709-3337.

Exterior lighting

03V14700039 vehicles affected

The problem
Certain heavy duty trucks fail to comply with the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." The view of one of the four back of cab reflectors is blocked by the exhaust system.
The risk
With the right reflector not being visible, the width of the vehicle is not readily apparent, increasing the risk of a crash.
The fix
Dealers will install two additional reflectors. Owner notification began june 4, 2003. 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 mack at 1-610-709-
