Cummins Recalls L9 Diesel Engines Due to Fuel Hose Separation Risk

Cummins is recalling L9 diesel engines because remote fuel filter hoses may separate, causing fuel leaks, fire risks, or engine stalls.

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 (fuel system) that explicitly increases the risk of fire and crash, meeting the criteria for a Severe rating.

Plain-English summary

Cummins, Inc. is recalling certain Cummins L9 diesel engines with part number D563027BX03. The recall addresses a defect in the remote fuel filter hoses, which may become separated from the fitting.

This separation can result in a fuel leak and a lack of fuel supply to the engine. A fuel leak in the presence of an ignition source increases the risk of a fire. Additionally, a lack of fuel can cause an engine stall, increasing the risk of a crash.

Dealers will replace the fuel filter hoses free of charge. Owner notification letters were mailed on July 8, 2024. Owners may contact Cummins customer service at 1-800-286-6467 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
