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.

Risk: If the fuel tank falls, there is the potential for the tank to ignite, resulting in personal injury, vehicle and property damage.

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.

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.

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.

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.
