Bosch CP4 Fuel Pump: A Class Action Lawsuit | Nordgren Law: Automotive Litigation and Lemon Law

In recent years, the Bosch CP4 fuel pump has been the subject of numerous class-action lawsuits in the United States. The lawsuits claim that the pump is defective and prone to premature failure, and that the defendants were aware of the defects but continued to sell their products anyway. In this article, we’ll explore the allegations made in the lawsuits and what it means for vehicle owners and potential buyers.

What is the Bosch CP4 Fuel Pump?

The Bosch CP4 fuel pump is a high-pressure fuel pump used in modern diesel engines. It’s designed to provide precise fuel delivery under high pressures but has faced scrutiny over its reliability and durability. The pump operates using a plunger and barrel design, and is driven by the engine’s camshaft. The CP4 pump is often used in light and heavy-duty diesel vehicles and is commonly found in vehicles manufactured by companies such as General Motors, Ford, and Ram.

Allegations in the Class-Action Lawsuits

Class-action lawsuits against Bosch and other manufacturers, such as FCA US, LLC, General Motors, and Ford Motor Company, claim that the CP4 fuel pump is defective and prone to premature failure, and that the defendants were aware of the defects but continued to sell their products anyway. The central allegations are as follows:

  1. Defective design: The plaintiffs claimed that the Bosch CP4 fuel pump was defectively designed, making it prone to cracking and leaking, which led to engine damage and costly repairs.
  2. Awareness of defects: The plaintiffs alleged that the defendants were aware of the defects in the pump, but continued to sell it anyway, without adequately warning consumers of the issues.
  3. Misrepresentation: The plaintiffs claimed that the defendants made false and misleading statements about the pump’s performance, reliability, and durability, which induced consumers to purchase vehicles equipped with the pump.
  4. Unjust enrichment: The plaintiffs claimed that the defendants unjustly enriched themselves by selling a product that was defective and prone to failure, and by collecting fees for repairs and replacements of the pump.

Outcome of the Lawsuit

The outcome of the class-action lawsuits regarding the CP4 fuel pump is unclear. Class-action lawsuits can take years to resolve, and the outcome may depend on various factors, including the strength of the evidence presented by the plaintiffs and the defenses raised by the opposition.

What Does This Mean for Vehicle Owners and Potential Buyers?
