Next thing you know the naysayers will claim “they’ll say it was “bad air.”” Everyone knows the fuel tank thing is a reach. A far reach. Not everything is doom and gloom, especially when it comes to these trucks.

Be glad you have a 2018 with CP3 pump.

Did you read the posts on the link provided?

From the original poster:
"Posted Sept 20th 2020.
Latest update - I heard from the service advisor at the Victorville dealership that the parts to repair the truck will not be available until December 15th.

Beyond frustrating."

I would not touch one of these CP4.2 equiped trucks with a 10 foot pole.

Another post from today in that same thread.

"Hello all. New here. I had almost an identical experience. Im now 2 weeks out from CP4 failure. Brand new 2020 3500 dually with only 7k miles. I have a case number with FCA but they have not responded in days. They told me they’d get me a 3500 rental but it hasnt materialized. I drove a 97 to almost 400k miles. I drove a 2011 to 200k miles. I was NEVER stranded on the side of the road all day waiting to be towed. Trailer towing in Phoenix was $225/hr. Customer care couldnt get me a truck tow either so I had to pay out of pocket. This absolutely insane. Even if they do get it fixed months from now I wont be able to ever trust the truck again. I really have no choice but to go find a used 4th gen truck or go to GM. If you are selling a 70k dollar product there just has to be accountability. The dealers dont want to be involved at all, they just push to fca customer care. Sounds like I need a lawyer."

I could just imagine being halfway between Wa and Az towing the TT and have CP4.2 failure that is not fixable for months!
 
HHmmm...could cost RAM/Cummins dearly. But how many failures on how many 2019-2020 trucks?

Nobody is going to tell you the answer to that question. People buy these trucks to use, hauling, towing, seeing America and having a failure that takes months to get parts for is not something that I would want to happen. I retired in June of 2006 and the 2001.5 RAM did extended West Coast trips that fall and the following. Then in 2008-09 winter we started snowbirding for the winter in Arizona. The 2001.5 did 7 round trips. In Sept of 2015 we bought the new RAM and it did a round trip with the older 29' 5th wheel, then 2 round trips with the 39' 5th along with a trip back at Christmas towing a box trailer to bring back furniture for the new park model. Then we have done 2.5 round trips with a 22.5' travel trailer. Just can not imagine being in the middle of one of these trips and have a dealer tell me parts were months out!
 
Although still a PITA if the truck is down for 30 days in almost any state they have to replace it. No need to get an attorney, just call FCA and document you want it replaced and it has been down 30 days. It's the law in almost every state, and the penalty for refusing your request can get quite large.
I do this stuff quite regularly (except for last 6 months) and at least in CA an attorney will drag it out for months or years to get a payday for themselves. Most could care less about you or your need for a truck.
 
Oh we have people here on the Forum that could check out how the demand is within the dealer network for the CP4.2

Still remember this, there has always been failures and there will always be failures - the only point is how many.

We are at the same point here as with the ECO - 99 happy owners compared to one (or less!) that experience a problem. The problem is that with the forums we start out with single cases and the whole majority that doesn't break isn't visible.

Within the last two years they sold probably hundreds of thousands of these Rams - if the CP4.2 would be a real problem we would be OVERWHELMED with complaints in this forum here very day.

It is nonsens to make an elephant out of a mouse.
 
Right up to the point that it is your mouse that is broken!

That can happen with ANY vehicle that is on the market today.
Everything can and will fail, we explained it more then once that the manufacturer has a pre determined expected rate of fails for any given Component of the vehicle.

Most failures of a 1000 dollar item do not add up to a 10K to 12K final bill.

Ford quickly repurchased my 2019 F250 Roush Edition Powerstroke after I racked up 32 days in service in the first 7 weeks of ownership... It had a front end vibration they could not fix....Handed me a check and paid the bank. The truck didn't get lemoned though as Ford kept it in house. Mercedes Benz buy-back was a bit more drawn out and I had to deal with a 3rd party mediator when my 2016 S550 sedan was lemoned as it had 47 days total in service... All they had to do was fix the rough idle issue but wouldn't even as to put fresh spark plugs or swapping coil packs around to trouble shoot it. It was branded a lemon and MB ate it... Got a check and the bank got paid. California sucks in so many ways but at least consumer protection is A-OK. Say my 2019's CP4 failed and they said no parts for a month... I could lemon it then find me another 3rd gen 5.9 mega cab for my heavy needs and then order a 1500TRX. :D
 
Snoking, will you have never been around heavy duty construction/mining equipment. I have seen hydraulic pump failures that have taken out valves and hydraulic cylinders. Costing more than $50,000 in damage by the time everything was fix and back to working order. With the customer picking up the tab for the repair bill.

Just saying and it does get expensive sometimes when you own a vehicle.
 
When my VP44 failed, I changed it myself for $1065. No new injectors, fuel lines, tank etc. About 4 hour job.

Spoke with Son-in-law last evening; another 3500 (2020) pump blow up. This makes 3 trucks in less then a month. Dealer said there’s a recall coming. Not that I believe what a dealer says as we know lots of times, they are the last to know.
 
How about RAM replacing them ALL with the Desno HP4 pump that GM switched to. The HP4 uses flat tappet lifters. Not hearing issues with that one. GM also went with Denso solenoid injectors.

I’m at 9800 miles in a year and 2 months of towing my 27’ camper and associated camping trip site seeing. That’s all I really use it for and I never fret leaving the house. If you are going to be the type who obsesses over a remote chance of failure you should buy something else, or you will never be able to relax along your trips. I know I can have a heart attack at anytime but I still go about my life.
 
I imagine there is some high number (percentage) of Ram Cummins buyers who know nothing of TDR, Cummins Forum, etc... who know nothing about CP4, Aisin shifting problems, integrated brake controller issues, 12.0Nav etc, and don't know they should be unhappy or concerned about thier trucks.

Anyone having concerns about doing anything should not do it. We have the typical spread of opinions and facts about it. In the meantime, Ram and Cummins keep selling trucks and engines.

My BIL is having frame integrity and death wobble on his 2019 Ford F250. I dont know anybody who has late model Chevy, so not aware of any issues with them.

In the end, buy or don't buy... it's a personal choice. If Ram/Cummins doesn't work, maybe Ford or Chevy will. Something has to be problem free, right?

Cheers, Ron
