According to the firm's investigation, a defect in GM, Ford and FCA diesel CP4 fuel pumps essentially leaves vehicle owners driving “ticking time bombs,” according to the class-action lawsuit, with the potential for owners to suffer sudden and unexpected shutoff of the vehicle’s engine while it is in motion.

Millions of GM, Ford and FCA trucks are installed with the defective fuel pump that can suddenly fail without warning, causing a total fuel system failure and consequential engine failure resulting in an outrageously expensive repair bill. The defendants are also refusing to fix the trucks under warranty.  Additionally, repairs are fruitless, as no repair will fix the issue as long as the vehicle with the CP4 is being filled with U.S. diesel.

FUEL PUMP DEFECT EXPLAINED

The basis of this defect is the Bosch-supplied CP4 high pressure fuel pump.

Unbeknownst to truck owners, Bosch’s CP4 pump was never compatible with American fuel standards and not built to withstand the specifications for U.S. diesel fuel in terms of lubrication or water content.

As a result, the pump is forced to run dry and destroy itself as air bubbles allow metal to rub against metal. The pump secretly deposits metal shavings and debris throughout the fuel system and the engine.

Judge’s Order Upholds Claims vs. Ford
Description

In an order issued Nov. 2, 2020, U.S. District Judge Nelva Gonzales Ramos upheld claims of fraudulent concealment, violations of the Texas Deceptive Practices Act, implied warranty breach and a portion of unjust enrichment claims against Ford in a victory for truck owners bringing the lawsuit.

The opinion details the court’s findings and reasoning: “…Plaintiffs reference multiple instances of Ford personnel knowingly testing the CP4 pump with only specification-compliant fuel and acknowledging the lubricity scar/CP4 pump problem, along with the reality of prevalent non-compliant fuel in the market.” Judge Ramos also stated, “Ford’s failure to disclose the functional problems associated with the CP4 pump and the high price for repair caused them to overpay for their vehicles.”
