Ram and Jeep Recall EcoDiesel V6 Models: Fuel Pump Problems
This problem has been repeatedly reported on the Ram and Jeep forums. Now Stellantis has issued a recall for 3.0 EcoDiesel V6 fuel pumps. The problem is that Bosch CP4.2 high pressure fuel pumps send metal fragments throughout the fuel system. CP4.2 is known to cause fuel pump failures.
What happens to those Ram and Jeep diesel engines?
With the introduction of metal wicks into the fuel system, this can lead to fuel starvation and loss of power. Stellantis began investigating the issue earlier this year. The focus was on 2014-2020 Jeep Grand Cherokee and 2014-2019 Ram 1500 Classic trucks. Stellantis performed stall testing for EcoDiesel engines. The problem was that the CP4.2 fuel pumps were self-destructing.
Metallic debris was getting into the fuel lines, fuel rails and injectors causing starvation issues. But since it is not immediately noticeable, by the time the problems appear, it requires the replacement of most of these components. That, and flush the fuel line and gas tank. Many of these repairs can cost between $3,000 and $6,000 for the labor involved.
Trucks and jeeps built between June 2013 and mid-December 2019 are subject to this recall. If this is a problem, various problems can result. These include a malfunction light, “service electronic throttle control” light, noises from the fuel pump, and/or a gas leak. Specifically, the recall affects 29,279 Jeep Grand Cherokee models and 109,366 Ram Classic trucks.
Have any accidents related to this Jeep and Ram recall been reported?
According to Stellantis, it is not aware of any injuries or accidents caused by faulty Bosch fuel pumps. There have been three field reports, 215 customer support cases and 1,061 warranty claims associated with this recall.
The Bosch CP4.2 fuel pump is also known to have problems with air entering the system which kills the pump. Sometimes running the truck out of fuel, improper priming after a fuel filter change, or improper installation of the filter itself will cause the pump to fail. This and the circulation of the metal fragments above are its two biggest problems.
Were there any other 3.0 liter EcoDiesel issues?
In addition to Bosch pump issues, in 2019 Stellantis issued a partial recall of more than 100,000 2014-2019 Ram pickups with the 3.0-liter EcoDiesel V6 engine. It was for issues with the exhaust gas recirculation cooler. These EGR coolers reduce nitrogen oxide emissions. They reduce heat and pressure on diesel engines.
Then a class action lawsuit was announced for EGR cooler issues in August 2020 (Crawford v. Fiat Chrysler US LLC., 2:20-cv-12341-SJM-DRG). Numerous back-and-forth motions over the ensuing two years have finally resulted in a trial date beginning October 31, 2023. We will have to see if this lawsuit is settled before it goes to trial.
Regarding the recall issued today, owners will begin to see recall notices by the end of July. You must bring your Grand Cherokee or Ram Classic to the dealership. They will inspect the fuel system and replace the fuel pump. It also indicates that a service technician will replace additional fuel system components. However, Stellantis does not say if the warranty will cover them.
