Bosch’s CP4 Fuel Injection Pump

In November 2018, a class-action lawsuit was filed against Robert Bosch GMBH and several car manufacturers – including Ford and General Motors – for allegedly claiming that the Bosch CP4 fuel injection system is reliable, durable, powerful, and fuel efficient when, according to plaintiffs, a pump used in the system isn’t compatible with American diesel fuel, which results in engines failing without warning. (Martinez et al v. Robert Bosch GMBH et al, Case No. 18-cv-81500, S. D. FL.)
