- Affected:
- 317
- Defect:
- 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.
- Consequence:
- 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.
- Correction:
- 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.

- Defect:
- 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.
- Consequence:
- 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.

- Campaign:
- 07V401000 on 09/04/2007
- Component:
- Fuel system, diesel
- Manufactured:
- 12/31/2001 - 01/30/2007
- Affected:
- 35,649
- 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.
- Consequence:
- 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.
- Correction:
- 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.
