— An FCA Canada class-action lawsuit alleges that 2014-2020 Jeep Grand Cherokee and Ram 1500 diesel vehicles are equipped with defective Bosch CP4 fuel pumps.
The CP4 fuel pump relies on diesel fuel to lubricate the pump to prevent overheating and damage to the pump. But Canadian diesel supposedly won’t lubricate the pumps enough to keep them running properly.
The vehicles are equipped with 3.0L EcoDiesel engines and high-pressure fuel injection pumps that are allegedly incompatible with the lubricity of American diesel.
According to the Canadian lawsuit, the CP4 fuel pump is too brittle to handle North American diesel fuel, leading to a condition where metal parts rub against each other, creating chips of metal Metal shavings allegedly contaminate the fuel system and block fuel injectors.
This will supposedly cause the EcoDiesel engine to fail, something Chrysler allegedly forgot to tell customers.
The occupants of the Jeep and Ram and others on the roads are allegedly in danger when the vehicles are suddenly locked while driving. Drivers are then unable to restart the vehicles because the CP4 fuel pumps are destroyed.
The plaintiff claims that the CP4 fuel pump can damage an EcoDiesel engine by causing fuel spray to hit the cylinder wall and cause engine oil dilution that damages the engine. The cylinders are also worn from overheating and the exhaust valves and pistons are damaged.
According to the lawsuit, the problems can cause damage to turbochargers, cylinder heads and emissions systems.
The plaintiff claims that the damaged pump will burn the engine and the owner will have to pay at least $10,000 to replace the engine. However, the lawsuit alleges that the replacement engine will also fail because the same defective CP4 fuel pump is installed in the vehicle.
FCA Canada’s CP4 fuel pump lawsuit was filed in the Supreme Court of British Columbia: Lyndsey Sherwood, v. FCA Canada Inc., et al.
The plaintiff is represented by Garcha & Company.
