What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The source text explicitly states that the defect could result in personal injury and/or vehicle or property damage, which aligns with the rubric criterion for 'significant injury/property-damage reports' or risk of harm.

Plain-English summary

Westport Fuel Systems Inc is recalling certain 2007 and 2009 Westport ISX G Class 8 vehicles equipped with liquefied natural gas pumps. The recall addresses a manufacturing defect where the vent hole associated with the pump pressure relief valve may have been covered by a welding process.

This defect can render the pressure relief valve ineffective, resulting in the possible build-up of gas in the pump if the manual shut-off valve is closed. This condition could result in a sudden leak of high-pressure gas within the tank shroud and a slower leak of tank pressure, which could result in personal injury and/or vehicle or property damage.

Westport will inspect and correct the problem by upgrading to an automatic shut-off valve that does not use the vent hole. This service will be performed free of charge. The safety recall is expected to begin during May 2010. Owners may contact Inland Kenworth Fontana at 1-909-823-9955 and Inland Kenworth Montebello at 1-323-278-4100.
