Dodge DPF issues continue to frustrate owners


DODGE CUMMINS 6.7 OWNERS with DPF problems,

I feel your pain and frustration.  I recently received this email from a reader who had asked for some very specific advice regarding a possible trade-in deal vs. going the buy-back route.

I am sharing it with you, not to applaud myself but because I think she makes some very solid points and I don’t mind outing the dealer who is involved.

Maybe when the dealers realize that online reputation management is critical, they will rally to get Dodge to resolve this ongoing issue ethically.


Dear Sarah,

You have a raving fan in Scottsdale, AZ!!  I want to thank you so much for all your suggestions regarding possible remedies for the Diesel Particulate Filter clogging issues in our 2008 Dodge Ram 3500.


Your accessibility (I couldn’t believe you responded on a Sunday!), prompt responses, industry knowledge and assertive approach made us realize that after purchasing three Rams and a Jeep from Scottsdale Airpark Dodge/Ram/Chrysler/Jeep in Scottsdale, AZ, we deserved more consideration than they were willing to provide to remedy the on-going issues with clogging of the Diesel Particulate Filter assembly in our 2008 Dodge Ram 3500 Big Horn dually.

 The issue, as you have so well documented on your web site (the tab for Cummins Diesel Trucks), is the failure due to clogging of the Diesel Particulate Filter assembly in the 2007, 2008 and 2009 Dodge Ram 2500 and 3500 (and, according to several Diesel Forums on the internet, the 2010 as well!).

 On our vehicle this assembly has failed SIX times since we purchased the vehicle in April 2008!!  This is a serious safety issue because the vehicle either shuts down while you are driving it, slows to a crawl or won’t start.  This is particularly troublesome if it should happen to fail while we are hauling our horses and could result in serious injury to ourselves, our horses as well as to others.

 Not surprisingly, discussions with Chrysler were a big waste of time.  Chrysler bounced us back to Scottsdale Airpark Dodge/Ram/Chrysler/Jeep in Scottsdale, AZ who tried to get us to purchase a 2011 Ram by trading us out at a ridiculously low depreciated value for our 2008 Ram 3500 dually because of the known problems with the truck.  That ridiculous “offer” led me to do some research which led me to you. Based on the great (and free!) advice you gave us, we did not bite on the dealer’s “generous” (for them!) offer, and we are still in negotiations with them.  Only time will tell if they will do the right thing.

 Please advise your readers to (also known as lessons learned):

  1. Check out the Lemon Laws in their state (;
  2. document repeat service issues and determine if you have a “lemon” before the expiration date in your state to report a “lemon” (in Arizona, for example, the timing is 2 years or 24,000 miles, whichever is less);
  3. remember that the dealer wants to take money from your pocket and put it in his/hers – contact Sarah Lee at for prompt, honest and professional guidance;
  4. check out the class action complaint against Chrysler at
  5. (scroll down to “Vehicle Defect Litigation”) which alleges that the Dodge Ram 2500 and 3500 built between 2007 and 2009 is … “inherently and permanently defective because it fails to rid itself of diesel particulates”…
  6. document everything (verbal discussions; promises; keep email; etc.)

Sarah, thanks again for your expertise, your timely responses and your concern.  Please feel free to use this information in your testimonials, blogs, etc.

Best Regards,

Sandy, Scottsdale, AZ  5/2/11
