- The lawsuit claims the fuel pump was designed for European diesel, not U.S. diesel.
- Metal components can rub together, causing metal shavings to contaminate the fuel system.
- Repairing an engine damaged by the faulty fuel pump cost one plaintiff $22,000.
Nissan has been hit with a class action lawsuit in Tennessee that claims certain 2016-2019 Titan XD models equipped with a 5.0-liter Cummins diesel engine have defective Bosch CP4 high-pressure fuel injection pumps.
The lawsuit, which also includes Cummins, alleges the faulty fuel pump is equipped with internal metal components that can rub against each other, creating metal shavings that contaminate the fuel system. This can reportedly block the fuel injectors, damage the engine, and cost more than $10,000 to repair.

The seven plaintiffs who filed the lawsuit, all of which own a 2016-2019 Nissan Titan XD, claim that the fuel pump used was designed for European diesel, which offers better lubrication. That’s important as the fuel pump uses the fuel itself for lubrication to ensure the cam, pumping cylinders, and individual rollers work together seamlessly. U.S. diesel fuel is said to not offer the same lubrication qualities as its European counterpart.
In the case of plaintiff Richard Werts, his Titan XD had approximately 33,000 miles (~53,000 km) on the odometer when the “fuel pump failed catastrophically” in May 2020 as he was driving on the interstate near Baton Rouge, Louisiana.
He claims the truck completely shut off, requiring a tow to a local Nissan dealership for repair. Although he didn’t pay for the repair, he seeks compensation for the total purchase price of the truck and all out-of-pocket losses due to overpaying for the pickup.
In May 2023, a 2017 Titan XD purchased used by Texas resident Claude Harris experienced a fuel pump failure on a highway. His vehicle was no longer under warranty, and the dealership claimed the repair would cost an eye-watering $22,000, which his insurance company refused to cover. Harris is also one of the plaintiffs who has sued.
“These consumers are entitled to be reimbursed for the many millions of dollars Defendants fraudulently obtained from them, and to be compensated for their actual losses,” the lawsuit states. “Plaintiffs and Class members are also entitled to be compensated for the cost of repair as a proxy for overpayment at the time of sale for vehicles that have a defect that cannot be repaired.”
