2025 RAM 1500 BIGHORN 3.0 I HURRICANE twin-turbo, SO, 420HP - check engine light

[cpetku]

Another update to my situation, I’ve gotten the truck back from the dealership. I put a pause on flushing the fuel system for $1200. Technician said the fuel was a little cloudier than he would’ve liked to have seen and after leaving the fuel sample out over night he saw some bubbles sitting at the bottom of the sample. Just as well, looks like he was reading some misfires upon deceleration with all 6 cylinders when he test drove it besides the original code for misfires on start up of cylinders 3, 5, and a random misfire. I’m just going to cycle a couple of good tanks of fuel through and if the check engine light doesn’t come back I guess I’ll be good. If it does come back, I’ll be taking it back to the dealer to see what’s going on next.

It sounds like they didn't show you a sample of "contaminated fuel". The answer you describe from the tech would make me look for another dealership. When you told your plan to the Tech did you say the most famous phrase with Arnold's accent?

Well I had to call the dealership to get their service department to check to see if they had a response from the Stars thing…. Now they want to do a fuel system leak down test. And I’m sure they still don’t even have my truck in a bay so they are going to have to get something else out of the way just to bring my truck in to do this. Who tf knows how long it will take them to do that!

I’m sick of driving this POS Grand Cherokee they gave me for a loaner…

Could be worse, it could be a Compass or a Renegade......

Yes those would be worse… But I bought the truck so I could load the bed with tools and be able to do work, or to be able to pull my tandem axel trailer loaded to the gills with atv’s and dirt bikes if needed. I told the young girl that I’m pretty sure they don’t want me lugging 7-8 Milwaukee Packout cases in and out of the back end of one of their 2024 loaners and that it sure as hell can’t pull my trailer. She tried to make a joke about me having to pay for repairs then to which I didn’t quite laugh and replied with yea I don’t think I would.

Best part is that my truck hasn’t moved in over a week as I’m stuck here about to make my first payment for a vehicle that I got to drive for just over a week.

Update my 2025 Ram 1500 Laramie CEL issue...fuel pump supposed to be in mid next week (their fix atm)... Service guy asked what fuel I put in it ( I see where this is going...gonna try to blame me for the problem like some others on this thread). He said the Regional Service Tech is on the job with this issue and working with the dealership service techs to resolve. I use 91 octane, no ethanol, never any issue with my 2009 Ram 1500, drank it very well. He did admit there are three other 2025 Ram 1500s at the dealership with the same CEL issue getting serviced. Obviously their product is not on point...tic toc Stellantis....loyal Ram buyer here growing more impatient by the day...we might need a 2025 Dodge Ram 1500 Group Therapy thread..."show me where Stellantis hurt you"

I want this new truck to come so bad but I’m also concerned with all these CEL issues, I definitely think they’re more than likely electrical based or software based due to it being in both the SO i6 and the V6. But my last truck I bought last October was a lemon I would **** a brick if this one was too lol.

So far using nothing but Shell 93. 3,200 miles and no CEL issues yet nock on wood.

I had the dreaded CEL on my 2025 RAM 1500 SST @ 200 miles. Come to find out it was the octane level of fuel I was using. I was running a lower octane due to fuel prices but was told it should be using no less than 91. So, in true fashion I RTFM after the fact and been running 91 since. No CEL and much better performance from the SST.

So what does the owners manual have for fuel recommendation, running 91/93 octane will add a heck of alot more to operating costs?

I believe you are suppose to be able to use 87 octane in the Standard output and thier is no minum rating on the fuel door like the Highoutput has. That said Ram may need to rethink that or do some recalibrtions if using 87 is causing CEL lights. I know turbos normally run better with higher octane.
