Cummins Westport ISL G Engine Recall for Turbocharger Oil Leak Risk

Cummins is recalling Westport ISL G engines due to a turbocharger oil supply line that may leak, increasing the risk of fire near the exhaust manifold.

What this means for you

Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle defect (engine component interference) that creates an increased risk of fire, which aligns with the 'Severe' criteria for significant injury/property-damage reports or structural defects.

Plain-English summary

Cummins Inc. is recalling certain Westport ISL G engines manufactured between September 13, 2007, and September 23, 2015. These engines were sold for use exclusively in Mack Trucks and Navistar vehicles, both as original equipment and as replacement equipment.

The recall addresses a defect where the turbocharger oil supply line may contact or interfere with the turbocharger inlet elbow, clean air intake clamp, or air fuel control tube. This interference can result in an oil leak. If the oil leaks in the proximity of the engine exhaust manifold, there is an increased risk of a fire.

Cummins will notify owners, and dealers will inspect for oil supply line interference or damage. The corrective action involves eliminating the interference and replacing the oil supply line as necessary, free of charge. The recall began on November 23, 2015. Owners may contact Cummins at 1-800-343-7357 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
