Here's What Happens When Your Flawed Bosch CP4.2 Fuel Pump Explodes

What part of FCA has to wait until Bosch can make tens of thousands of new pumps do you not understand??? Once the new pump is made it takes time to get them from Germany to the USA, oh lets not forget Covid happened that also slowed every thing down and yet you think FCA can just pull a new CP 3 out of the back side

My 2022 came with a cp3 pump an I knew of 3 local guys waiting on one to replace their cp4. ALL manufacturers should of stopped producing on al diesel truck untill it was under control. I dealt with plenty of material shortage and when I need to do a repair on a previous project my current one lacked material.

By 2022 they well knew of the CP4.2 issues.

You are FCA sympathetic. How is that so? Obviously you are not a Ram 3500 owner. You have lost all credibility with me. Good day, sir.

Not FCA sympathetic, I was taught not be closed minded and not see things from just one side... FYI many 2019 2500 trucks also have the CP4 pump installed it not just the 3500 trucks, but then you would know that if you took time to do more reading...

I am not sure why there are people on here saying to wait and be patient when it has been a year for this guy!! If anyone here would have a blown injection pump, or anything else messed up with their truck causing them to not be able to use their vehicle for a year and they wouldn't be pissed, you are a much better man than I. It is FCA's fault for putting crap on the cummins. Don't put the crap CP4 on it and they would have been fine. There was plenty of info of them grenading themselves prior to FCA using them. This is not this fellas fault. Cut him some slack. Anyone would be rightfully upset and wanting it corrected.

Thank you. You're right. FCA knew it was a faulty pump and went ahead and used it anyway. Almost as soon as I bought my 3500 I began using a couple of fuel additives that came recommended by a Ram Tech friend. For prevention. Lucas Cetane Power Booster, and Diesel Stabil. At home, between any long trips, I also never let the tank drop below 3/4 full. Less air in the tank, the fresher the fuel stays.

OP's CP 4 never failed, his truck is still running, read a post a few hours ago from guy who just had his CP4 replaced and got truck back today, he mentioned that his truck has 105K and the CP4 was still working fine. The ones I do feel for are those who trucks pump failed and took out the whole fuel system an had to wait because of poor dealerships who refused or were slow to do the work because they could get more $$$ for non warranty work..

I see. I took it that was a pic of his CP4. That changes alot. If it is still running, keep driving and pray...if it was broken down and a year had passed I would be going ape****

I had my pump replaced in the summer on my '20.
I didn't really care if it blew or not. If it blew, then Ram has to replace an engine if need be.

I had to go to two dealers to get it done. First dealer had their diesel mechanic quit. Second dealer took me right in after they submitted my VIN to Ram. Neither of these dealers are the dealer I bought the truck from.

I've not been keen on going around, shopping for dealerships that will replace the pump. They're all FCA. All dealerships must comply and fulfill the legal obligation to address and remedy a serious safety issue.

It seems Bosch has gone to the crapper along with many others.
They used to be highly renowned for excellence, but I've seen many complaints lately about their products.
I'm taking them off my go-to list of manufacturers. They can no longer be trusted.

If you want it repaired, that may be what you have to do. Otherwise, if the dealer you have chosen to use does not have the pump they cannot replace it with a part they don't have.

I just went through a 9 month ordeal with my 2019 Expedition between Ford and the dealership with a transmission repair that DID have my vehicle inoperable and in the shop on a lift the entire time. Ford was waiting on the manufacturer of the transmission components to build the redesigned internals. I called every dealership between the east coast and west to try and find a $30 parking pawl assembly. They didn't exist.

Dealerships are NOT FCA, or Ford, or GM, etc... They are independently owned and as we learned the hard way they do not have access to many of the tools that FCA/Ford/GM, etc.. have. I was involved in their process every step of the way. The dealers have to put in a request and wait. There is literally nothing more that they can do. They are compelled to comply with recalls but are at the mercy of the manufacturer (in this instance, FCA). In this case, FCA and/or Cummins is at the mercy of Bosch who may or may not be at the mercy of some other supplier producing the new internals needed for the pump. The supply chain is severely hurting right now.

I'm not a dealership nor a manufacturer advocate (ESPECIALLY after our debacle with Ford) but sometimes you just have to take a step back and really look at the whole picture. Spending decades running a manufacturing plant, you learn quickly that sometimes you are at the mercy of your supplier and no amount of threatening or screaming solves the problem. Before that I worked as a service writer and dealt with the same sort of issues. Sometimes the dealerships really are doing what they can. If you don't think this one is.... it IS on you to find a new one. You get a choice with who you use.

However - the second you mention an attorney, all bets are off. Any goodwill that you may have had with the dealer or an FCA case manager is gone. Your attorney will only speak to their legal team from that point on and you'll find out even less.

I don't know anything about this fuel pump or diesel engines for that matter.

If my truck was held up for a year, I'd be looking for the part myself. If it truly was not available, can't a part from another manufacturer be used? Nearly every part that needs replacement on every vehicle is usually available from different manufacturers.
If you are really desperate, how about a used one from a wrecked truck?

I get that it's a recall and there should be no cost, but its rediculous that any vehicle should be incapacitated for such a long period of time.

If you were able to find a replacement, whether Bosch or other brand, and it needs to be programmed, I'm sure you can find a dealer that can do that for you.

Again, I don't know much about this pump. I'm just looking at this from my perspective.

FCA will not reimburse if one pays out of pocket for a new pump and programming.

+1 on independently owned and what is stated here. No dealer is going to solve our issue when they are either in a situation of not having parts in hand, or place customer in a profitability order of who they focus on first - meaning making more profit from a paying customer vs. one under warranty work from FCA covered repairs.

I have a perfect example in my area, one dealer is the worst for working with and the other has been a very positive experience. One bad interaction with the worst one whom I had been taking my vehicles to for years made me reach out to the other and to date I couldn't be happier with finding that out - I guess anyone can wait around for a single dealership source to "help" us, but at some point we also have to help ourselves and shop around (whether it be dealer or parts themselves) IMO.

I get that, but it's better than having your truck sit idle for years waiting for them.

Sue them later. You might have a case. Document everything. Show how they were negligent in repairing the recall in a timely manner. Just imagine the cost of a rental or some other form of temporary replacement you might incur.

Worse scenario, you had to pay out of pocket to fix your truck, but at least it's fixed.

Having a $40k-$60k truck sitting idle or pay out of pocket. Seems fixing it yourself or having a trusted independent shop do it makes more sense.
Take the loss and try to sue them later.

I went through the same thing with our Expedition. Ford would not approve me to buy my own parts. The part had to come from Ford, or the dealer had to submit a request to use the alternate part, get it approved by the warranty and Engineering team after they can confirm that it meets or exceeds OEM specifications, and then the dealer could submit to reimburse me. I'd imagine FCA works the same way.

It was their short way of saying... if you stick an aftermarket part in the vehicle that we didn't approve, your warranty is null and void. But you'd be surprised to know that with some parts (especially on a fairly new vehicle) there really isn't an aftermarket for them and none are available. I'm not sure that there is a replacement option for the CP4 pumps aside from Bosch.

So every time this comes up it makes me think of the dream station CPAP recall. It's been nearly 2 years since my girlfriend was notified of the recall and no eta on a new one. Her medical supplier said our region is near the bottom of the list for replacements, and since it's voluntary there's nothing the government can do. Not sure if the CP4 pump recall is voluntary or government mandated. If it's voluntary, the government will take a hands off approach and there's nothing that can be done about how long it takes, short of lemon law if it sits broken waiting for parts and your state has a lemon law clause.

My take would be to find out if the OP is still within the lemon law period. We let the dealer talk us into taking our Expedition back (it was driveable for a short period of time) while waiting on the tool to arrive. The car had 78k miles. We took it back in at 83k miles. Our lemon law says 8 years/80k miles and at least 30 consecutive days in the shop.

Ford would not waiver to even discuss a buyback since the car had 83k miles EVEN THOUGH the repair order was opened at 78k miles and was still open when we took it back in. So... if you want to attempt to lemon law it, I might suggest that the OP STOP DRIVING IT and start the process if it's applicable.

Purchased 35 months ago and now at 17,000 miles.
