Is There a Recall On The CP4 Pump? (2019 RAM CP4 Recall)
It is a mess. Whoever thought to green-light the CP4 pump certainly made a mistake and created a legal mess for different automakers and Bosch. Of course, not covering warranty secure repairs was another mistake made by those automakers.
Yes, there is and Dodge is late to the party. The recall for Ford and GM seems to have started back in 2018 and possibly in 2017. Dodge owners just started getting their recall notices in January of this year. There is a long list of vehicles affected by this failed part
To learn more about this recall just continue to read our article. It researches this issue and provides the best information possible so you know if your vehicle is on the many lists for repair. At least 6 lawsuits were filed back in 2018.
Is There a Recall On The CP4 Pump?
Yes, there is and it is not sure when the recall started. Most recent articles only focus on the current Dodge recall notice which began on the first of this year. Some of the vehicles have had this part for 11 years.
The oldest affected were the 2010 Chevy Express, Savana, and Sierra vans and trucks all of which had the Duramax LGH engine. The next oldest was specific 2011 Ford, GMC, & Chevy vehicles.
Dodge did not have a problem until 2014. Lawsuits did not start until about 2018 and one seems to have been filed in 2020. The complaints say that Ford would blame the failure on inferior fuels used by the owners and refused to fix the pumps.
Bosch is also a target of the lawsuits as they are the company that originally made the CP4 pumps. There has been no word on the results of these different cases or if the recalls were successful or not.
What Mileage do CP4 Pumps Fail?
It seems that on average, the failure mark is 100,000 miles. This would explain why many 2010 and 2011 vehicles did not report any problems for many years. Some have failed at 25,000 miles and up.
Some owners do not drive their diesel vehicles on a daily basis. They do not rack up the miles as quickly as other drivers have. What has saved Dodge from a lot of problems is that they did not incorporate this pump in their motors until 2019.
It took them only 2 years to see the problem and the company went back to the CP3 in 2021. Other automakers were not as on the ball as Dodge was for this particular part.
However, during those 2 years, the company sold over 200,000 vehicles with the CP4 and their massive recall just started. When these pumps failed, they have caused up to $15,000 in damage to the whole system.
Some owners cannot afford that expenditure and were frustrated their brands did not back their warranties.
What Happens When a CP4 Fails?
The results of this failure are quite extensive. The reason for the failure was that the CP-4 was originally made for European diesel fuel which is different and dirtier than American diesel fuel.
The ultra-low sulfur fuel did not lubricate the system well enough resulting in a chain of events that caused between $8,000 and $20,000 worth of engine damage.
When the lubrication is low, the metal-on-metal friction gets worse. This scenario means that metal was shaved and those shavings started to travel through the fuel system.
Because some of the engines this pump was installed in a closed loop system, those metal shavings were able to travel freely throughout the system as it bypassed any filters.
Those shavings were able to damage the pump, regulators, and injectors, which in turn stopped the vehicle from working until the expensive repairs could be done.
If you didn’t change back to the CP3 then you should put in an additive to help lubricate all the metal parts better.
RAM CP4 Fuel Pump Recall
It was Dodge’s or Ram’s new parent company that issued the recall. That company is called Stellantis and it seems to want to make its customers happy. The notices first started going out in January of this year to over 220,000 Dodge owners.
The vehicles that are affected by this recall are:
- 2019 to 2020 Ram 2500 (DJ) – 113,720 units built between October 11th, 2018 to November 13th, 2020.
- 2019 to 2020 Ram 3500 (D2) – 67,586 units built between October 18th, 2018 to November 13th, 2020.
- 2019 to 2020 Ram 3500 Chassis Cab (DD) – 11,384 units built between November 29th, 2018 to November 13th, 2020.
- 2019 to 2020 Ram 4500/5500 Chassis Cab (DP) – 29,720 units built between November 29th, 2018 to November 13th, 2020.
The recall seems to be only for those vehicles with the CP4.2 pump and not the CP4.1 model. Some people simply say the CP4 unit so that could refer to both model designs. Either way, you should check with Dodge to see if your vehicle qualifies for the repair service.
One of the problems in this issue is that some engines can be retrofitted to receive the CP3 pump while others cannot.
