Here is another Ram forum that has quite a bit of good information.

Don't know your situation but here, the difference in fuel costs between gas and diesel negates much of the arithmetic. Adding the diesel option can also negatively affect the payload as well (especially in a 3/4 ton).

Some of us don't want/need a diesel. The OP has mentioned several times that he wasn't interested in one. Let it go man.

correct. At work we have the 6.4 Ram 2500 4x4 and we also have a durmax 2500 4x4. Basically same trucks, but one is gas the other diesel. Ram has about 80,000 mi and the gmc has about 110,000.

Look at it per mile. Ram, about $1.09 a mile for this last year, and the gmc is about $1.94.

Remember we have diesel AND def. The fuel isn't the only cost. Add def. Add repairs which are always more expensive and more involved on the diesels.

Old job we had an 07 gmc 3500 DRW d-max. 2wd, 12' flat bed or maybe it was 11' I don't remember. They gave $12,500 for the truck used in 2012, and they sold the F250/7.3 PSD that they bought new in 2003. The F250 had 124,000 on it, "mostly" trouble free (tires, oil changes, one ICP sensor and a leaking oil cooler which Ford took care of). The D-max had 85,000 on it when they bought it, wasn't used hard.

The Dmax.
Broken transmission crossmember
Broken wire harness (alternator harness)
alternator failure 2x
broken engine harness
6 injectors leaking too much (they put in all 8 because downtime costs $$$)
Another crossmember broken-same one just at a later date.
Transmission failed (allison). They replaced the valve body and it was working again
transmission totally failed, cheaper to replace than to rebuild according to the transmisison shop (I trust them with my own stuff so I believe them).
then the turbo had to be replaced, could've been rebuilt but was same $$$ to replace it.

In 2020 they finally got rid of the pile of garbage. One would say we bought someone else's problem but everything checked out on it and the PO had all service records which checked out perfectly, and was all done at the GMC dealer. He cared for his stuff and it was obvious (he was also a customer). All told, the boss had to put a little over $20,000 worth of repairs into that truck. Injectors were $6500 alone, and transmission wasn't much less as I remember (reman trans). We did a lot of stuff at work that we could do as far as harnesses and crossmembers, brakes, cables, and a blend door but some stuff we just weren't able to do, because of backlogs, paying customers, etc....so we had to hire it out.

But yes the diesels always cost more to keep running and/or repair. My own F250 (7.3 PSD), I just replaced the ICP which was $123 (OEM Ford) and the EBP sensor which was also over $100. Gas engines don't have those sensors. I have a slight oil leak, I think it's the doghouse (CCV) tube but I haven't had time to look at it yet. Maybe tomorrow. A/C is out in the house so if I'm going to be hot, I might as well just go outside and do something productive. My truck also needs injector cups, which I think I can do myself but it's another expense. At 264,000 miles it's probably time to think about injectors too while the thing is apart. There's $2000+ and you don't buy new ones anymore. Some junk remans are cheaper but I don't do cheap stuff. I don't enjoy working on things like I used to.

As recommended by several of you I have looked at Ram forums and continue to go down that rabbit hole and have seen some problems, as you always do with any forum.
A couple of issues are the squeal/clicking noise, perhaps from the exhaust system. Some report only until warm, others say always there - and dealer say it’s normal???
The lifter issue is I know a common problem with both the 5.7 & 6.4 Hemi. I think my 5.7 may be starting to show signs of having this virus. I recently heard the tick on startup, but not since. Has this been “fixed” with newer model years?
Next, breaking exhaust manifold bolts on the 5.7 & 6.4 is another one I hear frequently.
My question to you guys is in your experience are these issues common, or am I only reading the bad news stories?
Not far enough down the rabbit hole yet, but what about transmission problems? So far from what I have found it is reliable.
Again, this would be for a 2023 or newer 2500 6.4L engine, not the diesel.
Thanks guys, for all the helpful info so far. (y)

From what I hear the 6.4 is a reliable, heavy duty engine, it's not even close to the 5.7. The 8 spd ZF's are nearly bullet proof and are one of the best autos out there. Just don't fall for the "lifetime" trans fluid BS. Change it at 50-60K. That service is a PITA, but do it anyway.

My 2015 6.4 has been very reliable. I bought it used but haven't had to do anything to it with close to 50K miles on it. My truck goes thru brakes and I had to replace the fuel pump once. No biggie, raised the bed and had at it. I have the HD 6spd Aisin (same trans as the cummins option). Changed the fluid once in it and it doesn't have any issues thus far. I do wish that I could have the 8 spd ZF, as my 6 spd falls on its face from first to second gear. It does have some decent engine braking in tow/haul mode. I also have a lot less ponies in my 6.4 as what you get in a regular 2500 or 3500 pickup. They de-tune the crap out of them in chassis/cab models.

Oh- one more thing. I added a cheap throttle controller to mine. Night and day difference. I don't think that the cheap ones are available for the newer(ish) Rams. I put one in my ford too, night and day difference. I can't stand a dead/lazy pedal. I think they are dangerous. I think the ones that I got were like these: https://www.amazon.com/YIBEICO-Cont...x=Ram+throttle+controller,aps,138&sr=8-6&th=1

One other thing to look for, do the 2500 and 3500 models negate MDS? I thought that they didn't have it which would be a bonus.

I had a 5.7 in my wifes grand cherokee (2014) limited. Engine started to tick a bit with 130K on it. The only other stuff I had to do on that one (other than routine service) was a water pump and a set of plugs. That's it. ZF 8 speed has been flawless. Gave that Jeep to a niece. She loves it.

Wifes new ride is a (2026) Durango. Yep, its a 5.7 and zf trans as well.

I think the 6.4L has the MDS. My 5.7L has it and I override by setting the Gear Limit button to 8th gear which shuts off the MDS and lets the transmission shift as usual.

I have a '25 2500 6.4L Laramie, Just put 10,000 miles on it towing a 12000# fifth wheel. Great truck! I have 4.10 gears and I get around 14-15 (hand calculated, not the EVIC) not towing and get about 7 - 1/2 towing. I love the truck. If you want to change anything with the computer, good luck, I have not found anyone that can reprogram a '25 ( they changed the coding for '25)

I had a '16 with the 6-speed and the tow/haul programming was terrible. This 8-speed works great.

Oh, yeah, I forgot....

Going from a 1500 to a 2500 - the suspension is a lot rougher but RAM has coil springs on the 2500's rear axle so not terrible. The steering is a lot less responsive - more turns lock to lock. It is higher off the ground. It is a truck, not a glorified car with a pickup bed.

I put those airbags that go inside the coil springs to help with the bounce. Worked fairly well.
