I don't know if there's been any changes but I posted the following in February on another topic:

My son is the head Ford diesel tech at his dealership. Talked to him last night and asked about his experience with the 6.7. They have not had a single injection pump or turbo replacement. They have had a "few" EGR problems with service vehicles that had many hours of idle time. They did have an early one with a cam/valve problem. Ford replaced that engine with a new one and had it sent back for autopsy. Mine only has 12K towing a 16K fiver for over 10K but hasn't seen the inside of a dealership but for one oil change when I was on the road.

Since then I have just over 20K on my 6.7 with 17.5K of that towing with no problems.

In addition like I mentioned earlier my cousin is a long time Ford diesel tech starting in '93. The dealership he works at sells Ford, Chrysler, Jeep, RAM. He basically now works full time on RAM cummins trucks simply because the repair work in the Ford shop has dropped significantly since the 6.7 PSD has been introduced. In addition this dealer sells ~ 4 Power Strokes to 1 Cummins yet there's more techs working in the Chrysler shop.

His experience on warranty repairs between Ford and RAM is that he never had a problem with Ford denying warranty and their process is fairly simple, and with Chrysler there's more red tape he has to go thru to get approval. One thing common is both manufactures are frugal with the time they pay for a particular warranty repair.

Took economics and statistics in college. Did survey work as part of my schooling.

Now how is this connected with the topic at hand?

Because simply put, two dealerships out of the thousands that exist here in the US (and Canada to boot) is a completely irrelevant sample size.

In other words, it means absolutely nothing. Now if we were talking say 100, 200 dealers, it would mean a lot more.

Results in any poll or survey mean something when there are more participants in any said survey /poll.

I could name two more local area Ford dealers that have told me no fuel pump problems. But even with these 4 now, it is still way too small a sample size.

We go with my 3% trouble rate (or even Fish's claimed 1%) out of 400,000 vehicles a year sold, that is somewhere between 4,000 and 12,000 vehicles with the fuel pump problem.

That would mean there have been many dealerships handling these, so for any survey to be relevant, it would have to be a very large number.

MD,
You can't even quote me correctly... I wrote .1% or 1 out of 1000.

I do agree that 1 dealer is statistically insignificant, but it's what I have to share. Having said that ever comment here is statistically insignificant so what's new.
