I posted this once before but I think it went to the wrong post.
We are interested in your lawsuit. We have a volvo 2008 cummins isx. We have had the truck for a year and replaced the EGR valve a month after it was purchased. Then about 10 months later it went out again and it was replaced. Now we are having other issues the truck's check engine light came on and the truck loses power (no throttle Fault codes MID128, PID131, and FMI2 (data erratic). After the truck sits for about 3-5 mins it will run again. Took to the Volvo dealer and they said we had a bad wire harness. We got it back on the road and not too long it was happening again same symptoms same fault codes. We took it to another Volvo dealer they said it was some pins that were bent on the cable of the turbo actuator. They said problem was solved. Back on the road again same problem with the same fault codes. Very frustrated! I owe a monthly payment which I am now behind on and have not been able to stay on the road long enough to make money and my account is wiped clean! Called Cummins and of course they were of no help because the truck is out of warranty. Please contact me

Wow im a retired trucker drove back in the 80s and 90s and sold my truck just when diesel reached 1.05 a gallon which was 2001 I never had any problems other then rebuilding my engine every 500,000 miles and it was a cat engine..... I feel bad about all your comments especially those with this BS egr vale which seems to be the biggest problem, back in my days there where no BS pollution devices like it is today which none of it really helps our air, it's just a political BS especially from the democrat party that are making all these BS changes in the trucking industries. If I were all of you I would go to Washington DC with every trucker and there rigs and protest about the high cost of Fuel and all these BS EPA regulations that are killing the trucking industries and Owner Operators, and I bet it will bring back the old trucking days where drivers and owners can make a living instead of making a living in shops all the time.

Experienced all the same problems mentioned above. I thought I was going to have to spend some serious bank. I shut the engine down to cool overnight. In the morning, I turned the key to the on position but did not crank for 15 to 20 seconds (closes the EGR valve). Flipped my hood forward and disconnected the lower EGR plug. Started her up and ran her without the annoying problems of the past. No more soot. No more loss of power. No more lousy fuel mileage. No more hiccups on a pull. I put a piece of electrical tape over the check engine light that stays lit but I have the Road Relay to indicate any other problems that may happen. I've ran it this way for 6 months without issue and haven't been more pleased with my trucks performance.

hello my name is Michael, im an o/o I own a 2009 international proster with serious regen issues, it doesn't regen itself or manual. ive lost my sense of smell and taste because of the fumes that reek into my cab...I cant get any suthland shop or Cummings to pin-point the issue...I really think they were rushed by government to put something together that hasn't been thoroughly proven...dpf system is killing drivers physically and with you.

The ISX is a bullet proof 1.5 million mile motor if guys would research the engine before dumping 5-8000.00 in it 4 time a year... Fuck the emissions, ditch the EGR system. Blockbit off or gut it n place the shell on... Pdi has software for egr warning light or black tape.... Clean manifold soot out. Oil temp will run higher but within spec temp. Water temp 200-205... No sluggish under power, increased hp. No delayed start etc... I put a 8000.00 pdi kit on.. Which was a gimmick.. It simply blocks off egr n software turns light off.. Try it your isx issues will stop. Ive had 2 and know a fleet of 30 isx. W million miles w delete done day one. Hope this helps

Truck driver slash mechanic over 35 years cummins isx is the biggest piece of crap ever made! You cant make any money. Its down every other week. Regen, turbos, egr, camshafts, sensors!!! Etc etc!!! Over and over. It never stops. I have lost my ass on these motors. I prefer peterbuilts. You didnt have alot of options. Now you got pacar engines. There not much better..cummtins needs there ass sued!!! I realize the govverment and there regulations have a lot to do with it..the technology is there but not yet perfected. Trucking companies are losing there ass.with all of these clean air motors.. I am going bac to a old c15 cat or a n14 cummins or a old series 60 Detroit.. California kiss my ass! No freight from me!

I would like to pass on a little experience I had last spring. I haul logs
with 2007 peterbilt 378 tri drive and Quad axle trailer hauling 143,000 lbs in
winter and 139,700 ibs in the summer. 475 ISX. On the last load this spring I unloaded left the mill and truck would barely pull itself. I was just sick thinking it would cost me thousands if I take it to a dealer. I carry an extra ECM so I changed it and it felt good for 30 seconds then lost power. Limped the truck home barely enough power to go up the hills.
When I got home I openned the hood and pondered what to do not knowing where to start and what should I take apart. I already had taken the EGR apart, cut the valve stem and welded it shut with stainless steel welding rod. took the pipe off the venturi, cut the pipe going into the venturi off and installed a plug in the pipe so no anti freeze can leek from egr cooler into motor.
So now what? I was looking at the turbo and for some reason I took a wrench put it on the bolt on the dump valve lever and was moving it up and odwn and all of a suden it snapped shut. then I knew what was happening. the dump valve was sticking open and not giving the engine any turbo boost. I also have a resistor on the fuel system and it pulls almost a good as my 2007 KW with same cofiguration and load with a brand new 565 ISX after changing the motor with a cracked block.

I'm in with joining the Cummins lawsuit. We purchased 6 of these with the intentions of buying 60 and had nothing but problems. It wouldn't be an issue if Cummins stood behind it.

Ok we are done with Cummins's Department and will be hiring a lawyer! Any one have any recommendations? Or if you want to join in we may start a class action suit, we have an interested attorney but he needs more people to get involved. So please contact me if you are interested in joining the fight for Cummins to take care of the issues we have all had!
We are having same issues. How may we contact your attorney?
