I really appreciate all the feed back I get from this forum as I do take the suggestions in for the dealer to consider. fact is that with this truck the only time that it seems to operate correctly is under a load (approx 15,000 lbs), tow/haul mode on, and exhaust break on, and at 70 plus miles...

There are updates but no answers. The forum that Chrysler/Stellantis mechanics are on showed where 2 other trucks that were doing virtually the same thing as mine, showed where the mechanics had replaced all the injectors in the engine and it had been over 6 months since they had heard anything...

I checked the RO, had to google the number but it shows to be 5w-40

Thanks for that info, sooner or later something is going to crop its ugly head up and we will find out what is happening with this truck. In the meantime I get to spend more money on diesel fuel for every time that thing regens and keeps my fuel mileage down to around 13 to 14 miles per gallon.

According to the dealership, and I don't know when they started this, but they say this engine takes 5w-30 full synthetic (i have a 2022) which is why I worded it the way I did. I have 5000 miles on that oil change, what kind of problems would the motor have if it has had the wrong oil in it...

Yes

You know, you might have something there. The oil tech was reprimanded for getting the inside of someone's vehicle dirty right before he did or truck. Then he also got the inside of our vehicle dirty. They ended up letting him go. What would happen if they put the old standby of 15w-40 oil in it...

Yes, all the sensors were replaced as well as the particulates filter. I can't say if they bypassed the wiring on both of them, but if they did one, why wouldn't the other? But that is second guessing and I am trying to avoid the word assume here.

They have already replaced that sensor on my truck. They thought maybe there was a bad wire in the harness, so they wired it directly from the PCM to the differential sensor to no avail.

Mine did after the 2nd time doing a regen to soon, when I mentioned that to them, they reprogrammed the PCM and changed it to set the code after either the 4th or 5th time. They have put pretty close to 1000 miles on my truck, I couldn't tell you what instruments they had hookd up to it and they...

The truck is supposed to regen every 24 hours of run time, unless the differential sensor is reading to great of back pressure in the DPF. It's my understanding that the gauge will go up as the pressure in that sensor goes up. Once it gets to roughly 50% it will do an automatic regen. If this...

I am not sure the grasshopper thing was really the problem. We ran through those in North Dakota, and I drove through the rest of N. Dakota, Wisconsin, all the way across the upper peninsula of Michigan to the bridge and then south to almost the Ohio border, without a problem. And without...

In case anyone is wondering about the outcome of this code P2459 that has plagued this 2022 RAM 3500, here is an update. Going on 6 months now, I have taken the truck back t the dealership 8 times. The last time they had the truck for a month while waiting for Stellantis to get their engineers...

The grasshoppers happened while coming back to Mich. from Wyoming. No codes were thrown until after we were back and had the oil changed in the truck. The oil change person did not check the air filter. We started receiving codes shortly after that. no towing involved since we have been back...

Well, it's just going to get started again as the check engine has come back on. I reset the trip odometer on the truck and brought the DPF gauge up on the screen and watched it. When the filter gets to 50% full, it initiates a regen which it did at 239 miles, again at 297 miles(setting check...

You mentioned the DPF gauge on the instrument panel, well I found it and have been watching it since I got the truck back from the dealer. I reset the trip odometer to zero and have left it on the dpf gauge to watch it. In just 239 miles and a little over 8 hours of run time the gauge hit 50%...

Finally got the truck back after the dealership had it for almost 2 weeks. It does not appear to be using any oil. The last thing they did was #11 on list check the turbo for oil leaking into the exhaust. In so doing they disconnected the batteries there by losing the code in the computer...

Ok sorry for the late reply as I had surgery on right eye, but I just went out to check the oil in the truck and to me it looks like they have overfilled it. it's a whole line above the safe area.

Yes That was all done when they replaced the DPF. I don't believe they have checked for oil consumption at this point. Which I question as the oil used for the first oil change was a full synthetic 10w-30 which they say is the recommended oil by Stellantis/Chrysler over the 15w-40 that was...

It has had very little idle time from me, although the dealer said that they did idle it for 20 to 30 minutes when they were working on it.
