This is a similar situation I have with two Super Duty trucks that I have experienced. Someone on this site the other day, referred to this CP4 issue to be around 1% of trucks. So far this poll appears to be near that result. Thanks for putting this together, it is very interesting to see these numbers. I also fuel at Open Road truck stops and hope to stay in the 99% of trouble free trucks.

I'm in the same boat except I don't know for sure if Ford is going to take care of it. Just trying to see what I can expect.

That was back in 2015. I had hauled it back to the dealer I bought it from on my own dime after multiple lift pump failures in 20,000 miles. They told me it needed a complete fuel system replacement. They did a buy back and I drove away with a new 2016. I have no idea if all the issues ever got fixed or not, or if they just got it running and sold ot to some other sucker.

Approx 4 mil on 32 6.7 currently. No CP4 related problems. Couple of them had gas thru them.
Also will find metal shavings in the housing from time to time.
If I include the other trucks that have been sold off/ crashed out or what not. 55 6.7s no CP4 problems either. No additives except anti-gel in the heart of the winter.
17 personal ones, most deleted, no issues.

You should put in more mileage data points, mine on my 2016 failed at 335,000. Generally I didn’t use fuel additives, however I do in my 2020.

I do think it's good that folks list their MY truck too, as some changes have been made over the years, namely them pinning the buckets in the 20+'s.

For what it’s worth...
Two very close friends of mine have had no issue with CP4s. One has a 2015 with 315k and one has a 17 with 90k. Both used for daily driving. The 2015 tows a fully stocked enclosed landscape trailer weekly. The 2017 tows an SVL75, 12k mini and plows heavily. Neither run additives. Both CCSB SRW 350s.

Neighbor had one go out on a '17 tow truck and another buddy had one fail on a '15 with high miles. Know someone who had a Duramax with a CP4 that failed and he switched to a CP3. Have 100k+ on a 2016 with no issues, never use an additive and it has a Gen2 DPK.

Had a friend that had a filter installed after the CP4 while having other work done. A while later, the CP4 went out and luckily the filter caught the debris. After that, he replaced it with the CP3.
I don't think the issue is guaranteed by any means, but it does raise some concern to most owners with a CP4.
