DEF Shelf Life!

Rick, your story made me look further into the CP4 failure on the Fords and I found several other stories similar to yours where the owners were left with no warranty. This issue played a LARGE part in my decision to leave Ford after 20 years and buy a Ram. So you can count an additional lost sale for Ford with my case. Thank you for your detailed posts on your saga because it saved me from making a huge mistake.

You're welcome...I appreciate your kind words...Your analysis of your risk tolerance and subsequent decision to buy a Ram instead of a Ford is the very part of the discussion that the Blue Koolaid Crowd has difficulty understanding. They love to downplay the 3% failure rate, not a number I have ever provided, as insignificant. I guess it is insignificant as long as it happens to the other guy...

The other significant shortage in their vision is in the "GM has repaired "all" of the Duramax CP4.2 HPFP failures under warranty with no questions asked" statement...Ford's stated company policy on HPFP failures is not customer friendly...and all HPFP repairs must be approved by a FSE...

Good Luck with your Ram...and I will up my confirmed kill count by one...

There was a thread sometime back now about a recall from Ford I believe on bad NOX sensors. Believe it was ambulance packages that got front row on this one, but pertained to the 6.7L diesel.

Directly pertains as I believe it is these same sensors connected to the good verus bad DEF being discussed here.

You are correct...both GM and Ford had DEF related emissions issues in 2011. NOX sensor failures were a big part of the problem. Ford battled through a lot of bad press on the various Ford web boards as they worked through the problem. I struggld with the issue a bit but remained patient...Ford finally ended the issue in April or May 2011...GM had enough issues that they applied for and were granted temporary EPA approval to disable the DEF system until they worked out their bugs...they also solved the problems in mid 2011 and all trucks with disabled DEF systems had to be returned to DEF operations or lose their warranty coverage...

Moving forward to today, the DEF/NOX sensor issues have shrunk to normal warranty repair expectations. There will be failures but because this is emissions related, the manufacturers will have a difficult time denying warranty.

Have a Great Day
