WHAT’S THE ISSUE?

Hagens Berman is investigating a dangerous defect in 2016-2019 Nissan Titan XD diesel trucks that can cause sudden, unexpected shutoff of the vehicle’s engine while it is in motion and potential engine failure. The defect has been linked to more than 432,000 trucks with a Bosch CP4 fuel pump and Cummins diesel engine. Catastrophic engine failure can occur as early as mile one.

FUEL INJECTION PUMP DEFECT EXPLAINED

Tens of thousands of Nissan diesel trucks are installed with the defective Bosch CP4 high-pressure fuel injection fuel pump. The defective fuel pump can fail suddenly without warning, causing a total fuel system failure and consequential engine failure, resulting in an expensive repair bill. More than 432,000 vehicles equipped with the CP4 pump have been subject to recall, with reports referring to the pump as a ticking “time bomb.” Catastrophic failure can occur as early as mile one, and repair costs for engine failure caused by the defect can run upwards of $10,000.

Nissan refuses to fix the trucks under warranty. Additionally, because the defect is triggered by the use of U.S. diesel, repairs to the fuel pump or engine are unsuccessful, as long as the vehicle is being filled with the same fuel.

ABOUT THE DEFECTIVE NISSAN CP4 PUMP

The CP4 pump was not designed to withstand U.S. diesel fuel specifications, but was designed and built to the specifications of European diesel, which has more lubricous fuel. When used with U.S. diesel, parts of the CP4 fuel injector can wear against one another and generate metal shavings that contaminate the fuel system. The metal shavings eventually cause the fuel injectors to become blocked, causing a full engine shutdown with no ability to restart. Repairs can cost at least $10,000, but according to attorneys, are ultimately futile, because it will not actually fix the fuel-related issue.

WHAT NISSAN KNEW ABOUT THE CP4 DEFECT

We believe Nissan was aware that the fuel injection pump was not designed to function effectively with American diesel fuel, knowingly selling tens of thousands of defective vehicles to its customers. The CP4 pump’s defective design has been known within the automotive industry for at least a decade. This flaw was nonetheless disregarded in the design, manufacture, marketing, sales and leases of Cummins-equipped Nissan Titan XD diesel trucks.

NISSAN'S ATTEMPT TO BLAME CONSUMERS

Immediately after the Titan XD hit the market, Nissan issued a Technical Service Bulletin directing dealer service technicians that CP4 fuel pump failures associated with what they called “[fuel] contamination,” were not covered by Nissan’s vehicle warranty. Nissan told technicians that it was the vehicle owner’s responsibility to ensure they were filling their tanks with “appropriate fluid/fuel.”

YOUR RIGHTS AS A VEHICLE OWNER

Hagens Berman believes that consumers have the right to replacement costs of vehicle parts and deserve a real answer from Nissan. Consumers shouldn't have to suffer for Nissan’s intentionally defective trucks. Owners deserve safety and peace of mind, and we believe Nissan should be held accountable for putting drivers at risk for serious injury or death.

HOW CAN A CLASS-ACTION LAWSUIT HELP?

Through a class-action lawsuit, individual consumers can collectively bring claims against large corporations that would otherwise have the upper hand, like Nissan. A class-action lawsuit seeks to level the playing field, bringing strength to collective action to change corrupt practices and negligent responses to customers. Though these measures do not bring immediate relief, they are a time-tested method of holding companies accountable for wrongdoing, including automakers’ failure to sell safe and reliable vehicles to their customers.

TOP AUTO LITIGATION FIRM

Hagens Berman is already pursuing two lawsuits against automakers regarding the use of the defective CP4 fuel pump, one against GM, Ford and Fiat Chrysler concerning certain Duramax, EcoDiesel and Power Stroke models, and one concerning Dodge RAM Cummins-equipped Heavy Duty Diesel trucks. Hagens Berman is one of the nation’s leading automotive law firms and has played a leading role in achieving the two largest automotive settlements on behalf of consumers. Your claim will be handled by attorneys experienced in automotive consumer law.

NO COST TO YOU

There is no cost or fee whatsoever involved in joining this action. In the event Hagens Berman or any other firm obtains a settlement that provides benefits to class members, the court will decide a reasonable fee to be awarded to the legal team for the class. In no case will any class member ever be asked to pay any out-of-pocket sum.
