What is wrong
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.
What can happen
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
Recall repairs are free of charge.
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.

A recall means the maker found a safety problem and offers a free fix; it does not mean every unit has the problem. Units affected are as reported by the company. Popular models sell more and so have more recalls and complaints. Official public data; texts are shortened. A dealer can tell whether a single vehicle still needs the repair.
