2025 Ram RHO Issues

[kaladin]

I ordered a RHO and received it on January 2nd. My drive home from the local dealer in Colorado didn't go as planned as there was a check engine light in the first 40 miles. I was driving under 55 MPH with no rapid accelerations. I ran my code reader and it popped something like 15 codes however, all of them were from the root cause of MISFIRE. Took it to the dealer and the fix was relatively quick. I was told it was something about an "update" but am not confident in the disclosure. Took it home and drove it another 100 miles with no issues. Almost when the break-in would have been complete it threw another 10 codes and the cruise control didn't work, auto braking system, steering assist, and there is a loss of power. I have taken it back to the dealer again, but I wanted a thread so others could see the issues I am having.

The day I bought the truck the delivery was delayed as the dealer said they were having issues connecting to the "Pod". I thought this was for the LowJack system but I am thinking it was the main computer for the truck.

The issue I had dinged a total of four times for the misfire-Twice on acceleration, and twice under cruising.

The cruise control system worked initially and I let it drive for about 20 miles without issue. The second time I tried to activate it there was an issue. It started up correctly, on a divided highway when I set the cruise control, then it suddenly started beeping loudly and swerved to the right for no reason.

I will update everyone as this progresses. I will also list the exact codes that I was seeing, but I don't have them with me now.

Disconnect your battery cables for a few minutes, let the electronics reset and then reconnect your cables. That solved a lot of my electrical gremlins with my 2025 Longhorn Limited. That was 6,000 (s)miles ago......all good now. Not ONE issue. Good luck with your RHO and report back to us!! You're going to love 540 HP under your right foot!!

Sometimes these rams come from the factory with a **** battery... could try replacing that if disconnecting the battery doesn't help... I would also check in the fuse box and make sure all the fuses are seated and pushed in cause mine weren't on my last three Rams... just couple things you can try... I have about 3000 miles on my '25 limited and love it! almost as fun as my '23 TRX...

Misfires on new RAM RHO? Maybe they filled the tank with less than 91 octane? Try filling the tank with some 93 to offset some lower octane gas and see if that helps. Just a stab in the dark, since the SO’s had initial misfire problems with 87 octane fuel. I hope you get to the root of the problem.

I just purchased a 2025 Tungsten with the HO. There was a slight delay at purchase, and they said they had to put in new batteries (I guess there is more than one??). As soon as I got on the highway I noticed the check engine light was on. At this time I called back to the dealership but the service department had closed so I took it back the next day. I drove about 40 miles round trip and did not notice any issue except for the light and occasional chime. The dealership took about a week to diagnose and told me it needed a new "power module". That was on backorder for a week and now saying it should arrive next week...

I really do not like all the misfire issues, battery issues, electrical issues, and a couple of reported melted cats and two blown engines on an RHO and a Tungsten. It's really making me have second thoughts about taking delivery of the RHO I have on order, especially since I live nowhere near Mark Dodge.

There is no way to know what percent of 2025s are having issues but it does seem more than 1 out of 50.

I dont have a RHO but I do have a 2025 limited that I ordered from MARK... so far I have about 3400 miles on it and I LOVE it. no issues with any of the stuff you listed... and I had a 2023 TRX with no issues they are both awesome trucks! so I would imagine RHO is going to be awesome as well... not sure if thats helpful haha

Just bought a new RHO and having similar issues. As soon as RPM's climb to 4500 and it shifts down, it would chime with cruise control inactive, automatic emergency breaking fault, and some other things. It would also stick in what ever gear I shifted down to, until I came to a complete stop. Dealer replaced batteries, but that didn't fix it. unit went into limp mode and I had to disconnect batteries to reset.

Throwing a Cam position code now I think. Shame the OP hasn't come back with any updates, as my dealer hasn't heard back from Dodge on what to do next. 200 miles on the odometer.

Update: My truck is running strong now. I had to do a hard reset of the computer, but i dont believe that was it. Honestly, i did some research and I believe the truck was never activated correctly. I dont think the dealership had the correct computer to activate my systems. I kept getting gremlins everytime i tried a new feature. I looked at my tracker on the truck and noticed the last time i took it in they drove it to Denver to another dealer. I have had 2 issues since but they were with auto braking and it was a loose connector and i found both of them and did the battery disconnect and it works fine. I have put 5k miles on the truck now driving to South Dakota and back twice and used auto drive, 4x4 through some pretty bad stuff, and i have to say the only complaint i have is the seats get a little uncomfortable compared to my last ram. I am installing a large graphic and getting windows tinted this weekend. Looking forward to some performance mods coming out to unlock some of this potential. For those wondering i only averaged low 14s for fuel milage on the trips. I did have no choice but to put about 10 gallons of 85 octane due to getting stuck in a ****ty town in Nebraska and didnt have any issues there either.

i didn't know 85 octane was a thing

To the guys with your new RHO's is the running boards deployable to step on to gain entry in your truck or not? It seems when looking at the Ram website the option is not clear on the running board option other than the price option lol, which is the same price as the power running board on the Laramie. Congratulations on your new Trucks! I think they're awesome trucks and hope the bugs gets worked out okay. I'm thinking hard of trading in my 2023 Laramie for one and order up one.

I have a local dealer with a base RHO with the fixed running board option. It's wide and definitely a step.

I ended up taking delivery and went over the checklist someone at the ram rho forums had. So far nothing seems wrong and no problems for the past 10 days.

I just got two engine codes on my 2025 at 820 miles for running rich at idle
