CP4 Class action lawsuit

I see that a class action lawsuit has been filed over the CP4 fuel pump: https://www.prnewswire.com/news-releases/american-diesel-trucks-are-time-bombs-lawsuit-filed-by-hilliard-martinez-gonzales-llp-300739064.html

From what I have heard here the claims in the lawsuit are somewhere between slight and gross exaggeration but are based on some solid evidence. It will be interesting to see where this goes.

As far as I can tell the Cummins in my Freightliner motorhome is not on the list of affected engines so hopefully I don't need to worry about it.
  • Yeah I just hit 110K w/o a problem. The level of complaints certainly seems to have decreased over a few years ago. Maybe the service depts are dealing with problems without trying to screw the owners like Ford especially was doing.
  • Interesting.

    They use a lot of definitive statements. Claiming manufacturers "always deny warranty coverage", and that by 100,000 miles "all truck owners see the costly results".

    I'm guessing there are more than a few 2012 vehicles out there with a quarter million miles that still have the original pump. I know that at least the early cp4 pumps were delicate, especially when water was introduced to the fuel system, and that's when I remember the manufacturers being a little finicky about replacement.

    Not defending Bosch or their cp4 pump, but here we go again with lawyers driving up the cost of the products we buy.
  • The problem with these class action suits is that the lawyers get tens of millions, the ONE client in who's name the suit was filed gets thousands, and everyone else gets a free small drink at Jack-in-the-Box.
