- The problem
- Mack trucks is recalling certain model year 2002-2005 mr and le heavy trucks, manufactured from february 1, 2002, through december 22, 2004. Over time, the vehicles load may result in fatigue cracks of the front axle beam. These cracks can propagate and result in complete fracture of the axle beam.

- If complete fracture occurs, the driver may lose control of the vehicle, increasing the risk of a crash.
- The fix
- This recall relates to previous recalls 09v-240 and 10v-069. Analysis of these recalls has shown that after the receiving the remedies, the axles may still crack. As such, mack trucks will replace the affected axles on any mr and le models configured as front-loader or side-loader refuse trucks. Axles on all other mr and le models will receive a mag-particle inspection and mack will replace any affected axle beams free of charge. The safety recall began iin july 2012.

- The problem
- Mack trucks is recalling certain model year 2002 through 2004 cl, cv, le, mr, rb, rd, and model year 2003 through 2004 dm heavy trucks manufactured from february 1, 2002 through september 30, 2003, equipped with axle beams manufactured by bharat forge. The axle beam may have transverse shear lines on the bottom of the axle from the trimming process.
- The risk
- These lines, if present, can promote initiation of cracks, which over time may possibly lead to axle beam failure and a vehicle crash can occur.
- The fix
- Mack will notify owners, inspect and replace any affected axle beams free of charge. The safety recall began on march 5, 2010. Owners may contact mack at 1-800-866-1177.
- The problem
- Mack is recalling 10,300 model year 2004 and 2005 cl, cv, dm, le, and rb and model year 2004 rd heavy trucks manufactured from october 1, 2003 through september 30, 2004, equipped with axle beams manufactured by bharat forge. The axle beam may have transverse shear lines on the bottom of the axle from the trimming process.
- The risk
- These lines, if present, can promote initiation of cracks, which over time may possibly lead to axle beam failure and a vehicle crash can occur.
- The fix
- Mack will notify owners, inspect and replace any affected axle beams free of charge. The safety recall began on august 14, 2009. Owners may contact mack at 1-800-866-1177.
- The problem
- On certain diesel powered heavy duty trucks, the bolts attaching the fuel tank mounting brackets to the frame may have insufficient torque and therefore may result in premature failure of the fuel tank mounting.
- The risk
- If the fuel tank falls, there is the potential for the tank to ignite, resulting in personal injury, vehicle and property damage.
- The fix
- Dealers will inspect and replace the fuel tank bracket mounting bolts free of charge. The recall began on february 6, 2006. Owners may contact mack trucks at 1-800-528-6586.
- The problem
- On certain heavy duty class 8 trucks equipped with holland air suspension systems, a transverse beam casting may fracture under normal loads. If a casting breaks when the vehicle is traveling on a roadway there is the potential for pieces of the casting to become projectiles and the suspension's transverse beam may drop down low enough to contact the road surface.
- The risk
- This will cause sparks that could potentially ignite and cause a fire.
- The fix
- Dealers will inspect and replace the defective transverse beam assemblies. The recall began on august 19, 2005. Owners may contact mack trucks at 610-709-2131.
- The problem
- On certain chassis built with lng engines, the nexgen lng tank's primary and secondary relief valves could fail to open and relieve tank pressure.
- The risk
- This could cause ice buildup on the discharge side of the primary and secondary pressure system allowing the relief system to freeze and become blocked resulting in over pressurization of the lng tanks creating the risk of catastrophic tank rupture which could cause serious injury or death.
- The fix
- Dealers will retrofit the lng tanks with a new primary relief valve pipe away tube and a new ventilated shroud. The recall began april 6, 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.
