Fuel Pumps

Ford 2017 F-350 Truck

The complaint for this class action is a massive document of over 860 pages. It alleges that Ford knew it should not use Bosch’s CP4 fuel pump in its diesel vehicles, but did so anyway. What was wrong with the CP4? Because US diesel fuel differs from European, the fuel pump does not work as it’s intended and eventually causes engine damage.

This is one of several recent class actions brought against General Motors for the use of Bosch’s CP4 fuel pumps in diesel vehicles. The complaint alleges that the CP4 cannot work properly with American diesel fuel, which does not provide enough lubrication. The result is eventual failures requiring the replacement of the fuel system.

Differences in US and European gasoline are at the heart of this class action. The complaint alleges that the CP4 fuel pump does not receive enough lubrication from US gas and that the pump’s creators and the auto makers who used it in their vehicles knew it. In fact, it claims that the use of the pumps amounts to a Racketeering Influenced and Corrupt Organizations (RICO) Act conspiracy, in addition to other violations of the law. 

Chrysler (FCA) has just settled a lawsuit alleging that its Dodge Durango and Jeep Grand Cherokee vehicles for model years 2011-2013 have internal fuel pump relays that may fail and cause the vehicle to stall, potentially leading to a crash. The complaint claims that signs of the problem include:
