What NHTSA recorded

Certain trucks equipped with nexgen liquid natural gas (lng) tanks are being recalled. The introduction of water into the discharge side of both the primary and secondary relief valves simultaneously and subsequent freezing in service can render the valves temporarily inoperative.

Possible consequence

If not inspected the risk of tank over-pressurization and a catastrophic tank rupture can occur, potentially resulting in serious injury or death.

Remedy

Nexgen will notify the customer, perform an inspection, and provide instructions for ordering and installing the retrofit kit. Owners should contact nexgen at 1-770-720-6780 or peterbilt at 1-940-591-4201.
