Automatic Regen too often

Shut the truck off this morning at 7:13am at mileage 48,821.9 and a dash gauge showing 25%
View attachment 77259
Started it back up at 2:35pm at the same mileage and the reading is higher now, showing 37.5% on the dash gauge lol

No passive regeneration on the way home.


I've had this happen quite often. Some times it would go back down or some times it would just got to regen. Seems to Goes with software or sensor issue.

I find mine also builds soot faster while driving on the highway over 60mph while climbing a grade of a few miles, flat highway doesn't build much. Surprisingly driving around town doesn't build as much, or it actually does but it can't really measure it properly until you get the speed and load up a bit, then it recalculates and gives the soot load swings


This really pissed my truck off. I pulled a grade from 25mph to 100mph to test the theory. It climbed soot in record time and went into regen.
 
3rd trip to the dealer with no fix yet. Here's the list of parts so far differential pressure sensor x2, maf sensor, correct air filter, new particle matter sensor and a reflash of the pcm.

This week I pressure tested the intake system and clamped off the CCV line for the test. No leaks at 20psi of shop air like the test states. Next I pressure tested my exhaust and no leaks from the down tube to the cats. All sensors and lines passed. Mpg is decent. 17 in town and 20-22 on the highway on the dream o meter on the dash calculating it.


I'm literally pulling my hair out with this truck. Constant regens and building soot. Here's my graph from a 10mile drive on the highway. Started at 2Grams and spiked to 3grams in a matter of minutes. Pulled off on to the exit ramp and spiked to 4 grams. If I drive in town only I build no soot. Driving on the highway is the only time I build soot in the dpf.


Does anyone have a list of confirmed fixes on these trucks?

Is it worth contacting ram cares?

From what I have gathered there is very few trucks getting fixed 100%. If they do get fixed it doesn't take long to go back to where it was. Just with the chats with the dealership there is no known fix and every truck is different. They will think they have their thumb on it and bam rouge truck and nothing fixes it.

After several STAR cases they finally replaced the DPF and that seemed to make my truck function properly. Until recently, anyway.

My pressure sensors weren't replaced, but everything else plus the DPF has been replaced. I was advised that once the DPF reaches 50% full it is basically impossible for a regen to clean it as it gets to be too much thus always regening. I have 3600 miles on the truck since getting it back. I had one instance where there was only 60 miles between regens. However after a 6400d treatment it has been fine the last 500 miles.

With that said, I think many on here have concluded that anything 18mpg and above on the highway means no passive regen as the EGTs don't get hot enough. Essentially it is too efficient or the inverse being the engine doesn't work hard enough. I have now also installed 295-65r20s on my truck. They are taller and weigh 2.5x more then the stock Firestones. I'm averaging about 17.5mpg, and the DPF screen hasn't moved from 0 since the install. I did the 6400d treatment and tire change within 24 hours of each other so I'm not which, or if possibly both, have helped.

Despite the 20mpg+, I think this is a tuning issue that causes the incorrect air/fuel ratio causing soot build up. I'm not sure if the tune issue gets fixed or not, but I know a dietician that has worked on these 22s and once they lose weight the issue seems resolved. He also pointed out that after the diet none of the trucks roll coal except maybe a spurt if you get on it from a stop or pulling a heavy load from a stop. To me it that would mean the soot issue is resolved after the diet.
 
I may have a legal remedy soon as well.
Hopefully if it works for you, you can share that remedy.

Part of me hopes the EPA will be reigned in with the somewhat recent Supreme Court decision that makes deleting not an issue.... or even better - the OEMs don't have to do what they're doing anymore.

I keep sending complaints in to the EPA on Ram... still nothing. Maybe we all send one in it could stir the pot lol.

That advice is incorrect. If everything is functioning correctly and the truck is given sufficient drive cycles, your DPF should never achieve more than 50% capacity, and even so, will still regenerate out properly at that level. The truck will regenerate the DPF even if the soot load is higher than 50%, the process just takes longer….hence the “automatic exhaust system regeneration in process continue driving” version of the driver alert message.

It took 86 owner-generated safety complaints for NHTSA to launch a full scale investigation into the K1 snap ring failures on the 2022 aisin transmissions. Only problem was, it took two years to convince enough people to take the 5 minutes to file an online complain.

I had 86 trucks on my k1 failures spreadsheet within the first two months of the issue first appearing, that was nearly 2 years prior to the investigation opening up.

There is great power in numbers, provided those numbers are handed to the right people.

Yep and the amount of regen issues are more. Even my write up for the attorney general got no feed back. If 80 people filed a complaint with EPA there would be movement I am sure. People are just too lazy and waiting for others to do the lifting or just trade it in at the first sight of problems.

Since your a Moderator how about getting Admin to make a separate thread "Are You Having Excessive Regen Problem - Report to NHTSA". Describe all the symptoms in the threads, create like a survey link and then give them NHTSA the National Highway Traffic Safety Administration link to the complaint form to file their complaint. Then the last question did you file a complaint with NHTSA? Since this a very important thread, it also needs to be separate not a sub topic to get lost in the shuffle. If I remember correctly you have a survey on this with over 100+ members that have registered with you, if it only took 80 with the snap ring issue, then 100 or more should get some attention!

Not a bad idea, however, I’m not sure this is something the NHTSA would look into or consider a safety issue, as it’s more of a malfunction of the engine / emissions. So far, it really hasn’t left anyone stranded. I am sure the safety aspect could be “stretched” into the realm of the possible / plausible, especially where in instances like @Dinky503 had fumes from regen entering the cabin. However, the vast majority just end up with regeneration cycles occurring more, fuel mileage dropping, and potentially long term engine damage. I would be happy to contribute where I can to such a thread and endeavor, I just wouldn’t have high hopes that the NHTSA would be the body for action on this. As of this morning there are 128 trucks registered on my regen frequency response form.

This would help a locked Thread with a counter on how many people filed. Links to everything on how to file as well.

Wouldn't the excessive fuel in the oil cause an engine failure while driving?
 
This is most of the things they replaced or tested on my truck in 8 months.

All recalls completed and latest flash.
Multiple STAR cases.
Multiple FCA super special mechanics.
Correct air filter.
New MAF sensor.
New CCV filter.
HPFP test.
New PCV filter.
New DPF.
Injector balance test.
Injectors pulled and bench tested.
Oil consumption test.
Rocker arms and push rods replaced.
Live truck data recording.
All injectors replaced.
Turbo and intercooler inspected.
DPF ground tested.
Main bearing inspection.
More live testing and recording.
6,000 miles.

Now looking at "EGR".

It would need to be EPA or attorney general. Still wishing I had a run away truck with all the oil I had at one time lmao.
