CP4.2 Bypass kit

"Customers of the new 2019 Ram/6.7 cummins... tighten your seatbelt because it's going to be a bumpy ride."

WHY?????

I thought the CP4.2 has been good on the fords since 2015???

From what I have been told CUMMINS does not give FCA a warranty. I would have assumed the same with Navistar and Ford.

I guess we all can assume the 6.0L impacted Ford's warranty policies with their customers, but no one outside of Ford or someone with internal knowledge can say for sure. It probably impacted their warranty contracts with vendors, but that too is just an assumption.

I was also I ford guy up to the 6.0 saga. I needed to buy a truck of that era but refused to get caught in the 6.0 mess.
I went with an 07 LBZ Duramax at the time. THat truck lasted 300K miles as my daily driver. I have not looked back.
Fortunately Ford finally produced a winner in the 6.7 and those dark days are behind them. Nevertheless the 6.0 did impact their warranty policies.

Now that the ram/6.7 cummins has the "ridiculous CP4 pump" (your description) are you a die hard Ram man?

And, your point being? That has nothing to do with what I stated that Navistar was suppose to be paying warranty for the 6.0L, but wasn't which is why Ford sued them. What you posted here is a lawsuit between the owners and Ford/Navistar, not Ford and Navistar like I stated. It got very ugly between the two because Navistar was not paying its share of warranty claims to make it right, and left Ford holding the bag.

Ford and Navistar Settle Diesel Engine Dispute


I have to say that I feel Fords pain in having to deal with Navistar. I have to fight with their corporate offices on a regular basis. They make a lot of empty promises, they consistently miss deadlines, they don't pay you when or the amount they are suppose to, their plans and policies are driven by emotions rather than facts and data, and their whole organization seems to have an anti-customer/dealer culture that only focuses one how their department looks in front of their executives. And my company is its largest customer/dealer group and one of the main reasons they actually gained market share in 2018.

My company has had to make it right with customer on many occasions when Navistar refused to even though it was their fault. I feel sorry for GM for going in on a joint venture with Navistar on their 4500/5500 trucks. I hope they don't get burned like many others have. I was hoping things would change at Navistar once Volkswagen started taking over these past few years, but it seems to be all the same.

The other guys had not just endured the 6.0 crisis and were more willing to do the right thing when it came to warranty

Most of the warranty for the 6.0L and 6.4L was on Navistar since it was their engine. Ford would pay the dealer and then file the warranty claim with Navistar to get reimbursed. Navistar started denying warranty from Ford and was one of many reasons why they parted ways with the 6.7L. They completely cut ties with the new F650/750 body styles that are no longer being built by Navistar.

I'm not sure how it all played out.But Ford took a major hit on the whole 6.0 saga. There was plenty of litigation to go around. In the end Ford suffered significant losses. Which had an impact on future warranty claims. Fearing more losses they denied legit fuel pump claims that others were paying.

Ford Motor Co. has agreed to settle a class-action lawsuit over claims that it sold defective diesel engines in its 2003-07 Super Duty pickups and E-series vans.

The now discontinued diesel 6-liter V-8, manufactured by Ford's former diesel engine supplier, Navistar International, had myriad problems with the fuel system, turbochargers and other major components.

According to the settlement, any U.S. purchaser and lessee of any 2003-07 Ford vehicle equipped with a 6-liter Power Stroke diesel engine is covered if the vehicle's exhaust gas recirculation (EGR) cooler and EGR valve, oil cooler, fuel injectors, or turbocharger was repaired, replaced or adjusted prior to 135,000 miles or six years.

Each component is given a reimbursement limit. In addition, according to the settlement, if a class member paid a $100 deductible more than once for repairs under the five-year/100,000-mile engine warranty, Ford will reimburse $50 each for the second through fifth deductible paid, up to a limit of $200 for four deductible payments.

The settlement resolves dozens of class-action lawsuits against the company and entitles owners to be able to claim between $50 and $825 in reimbursement for post-warranty repairs to their engine and engine components.

Poor engine quality, high repair costs and sinking customer satisfaction ended the relationship between Ford and Navistar, which had built every Power Stroke engine used in Ford's F-Series since 1994. In 2010, Ford replaced the Navistar diesel with a new 6.7-liter diesel V-8 that the company designed in-house. That engine is built in a plant in Mexico.

Some 6-liter failures were so severe that Ford had to replace complete engines. Ford also ended up buying back hundreds of trucks that couldn't be easily repaired. The engine problems dramatically increased Ford warranty costs and led to litigation with Navistar.

According to court documents, Ford will pay roughly 50 percent of the full value of the claims made in the class action and was ordered to pay $150,000, in total, to the 16 named plaintiffs.

Navistar, which was dismissed from the litigation, had no comment, according to a company spokesman.

Edmonds was testing a 2014 Eco Diesel when their Ecodiesels fragile CP4.2 failed during a review. Ram did an outstanding PR stunt by repairing the truck back in Detroit in order to keep the real problem from being reported by Edmonds.

There are 3 main attributes that can cause the fragile CP4 pump to fail:
1. Fuel Contamination (water, DEF, gasoline)
2. Air in the fuel line (typically happens after a filter change)
3. Manufacturing defects of the pump

The best implementation for a CP4 pump is to have really good fuel filtration for both particulates and water. A lift pump to ensure good priming of the pump after a filter change, but still requires correct filter installation and the proper priming process in which a lot of people don't follow.

On another note if anyone believes any auto manufacturer will cover a fuel system repair if there are any signs of rust, DEF and gasoline contamination are either pushing some false agenda or lives in some alternate universe. In addition there will be a time when your beloved warranty will expire and the issues I listed except for any manufacturing defects can still bite you and your wallet.

Didn't say anyone was right or wrong. I was just guessing as to why Ford turned down so many people saying it was bad fuel because maybe they felt they took the necessary precautions by having a lift pump, a primary filter, and lower filter change intervals. GM on the other hand seemed to take no precautions by not having a lift pump, not having a primary filter, and extending the fuel filter change interval another 7.5k miles versus previous years. GM had to do something since they didn't provide any way to prevent the issue in the first place which is probably why the issue is more prevalent on the GM side.

Again, not saying they are right, just saying what they probably thought.

Ford has been applying Pavlovian training to their customer base for years with the 6.0, 6.4 and V10 that spit out spark plugs, so they knew that these same customers would buy into(AKA overlook) any issues with the 6.7.

One can probably say the same about all of the makes at one point in time. From Rams notorious death wobble, cheap dashes that seem to fall apart back in to day, and the mountain of recalls I have been getting on my truck which reminds me I just got another even though they still haven't found a fix for the last one. GM is not immune either with their old 350 diesel, overheating issues in some years, and front drivelines falling apart. So you really can't say it that only one brand has its issues since all have had good and bad year models and engines.
