I think the point was it seemed too coincidental that the pump failed right after the recall was done. My pump/controller did the same thing but I was still under warranty. I attributed mine to the recall and the new programming that went with it.
Another example is the UCONNECT over-the-air update which was required to be installed (you could only put it off for so long). It created problems for some owners that, from what I have read here, became the owner's problem to fix.
Without having more info this is just more internet whining.The truck may have had issues before the recall was performed.I have had many trucks come in for recalls with unrelated issues.The owner hoping everything would be fixed for free.I saw very few pump failures most pump codes were wiring/connector problems
