Great news on the warranty coverage, junk on the 2 month time frame, that would suck bad
 
Can you tell us what happened and how, whenever you relax and get around to it, is everybody ok

My family and I were towing our 35ft 5th wheel up to Yosemite. It made it to the summit with no problems but as soon as the truck starting coasting down hill the car shut off with out warning. I lost power steering and brake assist. Luckily I was a able to coast down the hill to a turn out to stop. I thought it was really weird that there was no warning. No sputtering/ misfiring or loss of power. It just shut off and would not start like it ran out of fuel. What's even worse is the dealer tried to tell me I had put the wrong fuel in it. I know for a fact I hadn't and it did not have symptoms of the wrong fuel. After threatening to tow it to dealer I trusted they came back to say it was mis diagnosed and it didn't have the wrong fuel in the tank. It was a bad injection pump. I hope Dodge does something to rectify this issue in the future. At this point I have lost all confidence in my truck.
 
that's terrible but typical on the mis diag. hope your not down too long. big thing is everyone is safe and no mishaps. good luck.

Thats a horrible situation for your family to of been put in, ram should be ashamed. I don't know how you were able to stop it with all that weight going down a hill without it running. I was a commercial truck driver back in the day and that would of freaked me the heck out. If the dealer would of said that to us, I don't know if I would of been able to hit him before my wife got to him. It's extremely sad that fca is using us for test dummy, I just wonder at what point is the right thing done and what has to happen. Im very sorry for your family's experience and I'm glad your all physically ok
 
Everyone this is happening to needs to file a complaint with the NHTSA:


I'm betting RAM just hopes us 19-20 old pump owners just go away. The only way to force their hand is steps like that. Try and get the word out to those who have had problems on forums and FB groups. This is absolutely a safety issue as verified by the judge/court in the Dmax CP4 class action suit in Texas. Many will scoff or not be heard from again, but you never know, might actually get the ball rolling on them being forced to do something proactive.

They would be happy to see us all go away, bet they won't be happy to see us come back with suites and briefcases. :mad:
 
Ram cares do u wish to chime in at all other then contact you and help them further.....are you guys looking into this and hopefully a recall or something
Ram cares did not answer me when I asked the same question because I haven’t bought one of their ticking time bombs.....
this question would need to be asked by somebody that owns one of these trucks if you expect to get an answer which is doubtful.
You would think if they had a fix they would have answered the question especially since guys like me are still on the fence about buying a new truck!

glad you and your family escaped a catastrophic situation due to these pumps failing.
these type of stories keep coming it’s just a matter of time before this happens to someone that ends up killing themselves or someone else because of the cp4 Turning trucks into inoperable missiles....
I would like to think that they are working on a recall to fix this knowing that death could occur.....

Likely Ram cares has no answer cause they’d like to keep their jobs, until someone with a higher pay grade gives them something they can do to help, if they ever do...doubt you’ll be getting anything other than FCAs current standard of practice, which is to leave you without a truck for several months while they fit your truck with the next bosch bomb.

Well let’s hope this is all reaching FCA decision makers. Until I see some good decisions being made I’m going to make a good One on not buying one of their trucks.
 
If I were doing it, I would at the very minimum upgrade to that filter to stop all the shrapnel from taking out everything down stream of the pump and have my plan for tuning and CP3 swap ready to go, which would be done in my own garage once it happened. Warranty be damned, its not worth it.

I can tell you if my Bosch dishwasher had a CP4 in it I would lose sleep over the catastrophic side effects of the household
All joking aside. I did read on another form that there is no filter that can handle the psi of the pump.
 
I believe there are a few questions that need to be asked prior.

What is the actual failure rate?
How many people posted or registered on this board only after the CP4 took a dump? How many members have been signed up and actively posted prior to it blowing up?

People come to forums when they have problems unless they are the very small group of people that just like doing this. Failure rate could be under .5%, we just happen to have 15 people here that it failed on. As I read in another post, CP4 has been in play in other fields for years. If it truly was a ticking time bomb, it wouldn't have been used on the 5th (4.5) gen.
 
People coming to a forum to first-post about a failure and then disappear is nothing new. I've been on automotive forums since at least 2006.

The difference I see here is it's all the same issue and it's very frequent in comparison to the years of other problems with vehicles. It reminds me of the cylinder deactivation lifter failures of the GM 5.3. A similar catastrophic failure concern. Apparently, FCA has the same problem with the 6.4s.

Thing is, the number of CP4 crap out posts for 1.75 model years worth of vehicles is starting to mount. Other models have hundreds of thousands of vehicles out there with a certain amount of forum failure posts. This 19-20 RAM CP4 garbage is starting to catch up quick and it's still an infant comparatively.

FCA didn't help the controversy by issuing a redesigned pump before the 2020 model year was even up. With no apparent reason given for why they made the change which is even more suspicious. If it was just NVH why didn't they wait for the 2021s to make the change? Why are people having to wait so long for pump replacements? Is it really the Rona or is it also that they have to wait for Bosch to crank out the fix-it pumps and throw away their stock of crap pumps?

This whole thing reeks of BS. I have a feeling that FCA will roll the dice with people bitching about the 2019 to August 2020 builds and just wish it away. If the new pump holds, they'll likely make 10 years of them and we'll be known as the couple years to avoid. You know, years from now when someone asks about getting a 5 Gen Cummins, posts will say "yeah, great truck, but keep away from the 19-20! Go for a 21-25!" :rolleyes:
 
I keep reading questions about the actual failure rate. Well, obviously, they don't furnish that information. But, here in the real world, let's look at reality. The Duramax ran the CP3, then went to the CP4. GM stupidity aside for not running a lift pump, but there was no class action for CP3 failures. Hmmmm. Dodge common rail trucks ran the CP3 from 2003-2018, and went to the CP4 in 2019, and sudenly there are people showing up with CP4 failures. Are there fuel stations labeled "CP3 Trucks Only" that dispense magic fuel? No, in the real world, buying real fuel, from real fuel stations the CP4 just does not cut the mustard. It is a bean counter POS. That's the real world.
