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.
