Thanks Huntindog. Correct info is nice to have.

In that case, we may actually have our first forum event of a failed Bosch CP 4.2 in a Duramax.

Some avid readers may recall a long thread in the Fifth Wheel part of the forum about a user having truck problems near St George Utah. He was mostly concerned with moving the fifth wheel to a proper location, and the truck was barely even mentioned.

However, out of curiosity I PM'ed this member. He replied back to me his vehicle was a 2011 Duramax and the HPFP had gone bad on it during his trip.

So possibility surely exists it was the CP 4.2. And it was on a Duramax.

VW has been under investigation by the NHTSA for failures of the Bosch CP 4.1 pump in their diesels. Ford and GM I believe both got requests from NHTSA for information about their use of the CP 4.2 pumps.

I read the responses to NHTSA from Ford and GM.
At least the summary version. There is more detailed info that one can get, but when I tried, my computer wouldn't open it.

So from the summary, Both Ford and GM has had failures. GMs rate is said to be higher than Fords, but I "think" that may be only warrantied repairs. Since Ford has been known to not honor the warranty, they should show a lower failure rate than GM which has a much better reputation in this regard....In fact when I last looked into it, there was not a single case on any forum about GM not honoring the warranty.. Ford had several. Not sure if that is still the case or not.as I don't visit all the forums so much anymore. Just the Dieselplace every now and then.

At any rate, I never said a thing on this thread about Fords use of the 4.2 HPFP. GM uses it too, so I don't see much of a difference between the two in this regard.

In the emissions area, the two chose different paths. I think the GMs approach is the better one, but I can see why Ford might want to go the way they did. This is all new to the big 3. Heck up until now, Dodge was still stuck doing it the old way, (no urea) Which both Ford and GM gave up on in 2011.

What probably troubles me the most is the radiator situation. Ford has had trouble with them now since at least 2008.
What gives? It's not like Ford had to reinvent the wheel. It's a radiator. Millions of cars are produced every year with an acceptable (very low) failure rate. But on the Ford forums a common post starts off as "Well it's my turn"

But on the Chevy forum a common post starts off as "LML Head Gaskets" at the DieselPlace. It seams like there's a lot of these epidemic head gasket failures and GM has gone to a cheaper head gasket supplier and/or bolt. What gives? It's not like Chevy had to reinvent the wheel. It's a head gasket and bolts. :R
