2025 Ram Rebel X - Check Engine Light

[Hustlerpunk]

Got my brand new Ram on Thursday which I ordered on July 12th. Driving last evening I got a check engine light. Less than 130 miles on it and it came on. Light hasn't shut off, didn't throw me any kind of notification and the Ram connect health report isn't showing an issue. I am praying when I take it back tomorrow that there isn't a big issue and this is just a fluke....

Might just be the mis-fire code that a few people are getting. How is it driving?

 

[Hustlerpunk]

It drives perfectly fine otherwise. No flashing check engine indicator, just a solid indicator light. I hadn't heard about the misfire code. Simple fix?

Buy a cheap OBDII reader on Amazon, they usually start at $15 or so. Use the Torque phone app and check the code. Hopefully just a minor emissions code, you can clear it with the app, and see if it pops up again.

I personally would leave the code up and have the dealer take a look.

I got a check engine light on my 2025 Ram recently. I bought the truck in September. The check engine light turned out to be related to something with the evap system. They said there was an update for it and performed the update, took a few minutes, and sent me on my way. I asked about the misfire update, but they said my truck didn't show any misfires codes so they did not do the the misfire update.

Took it in yesterday. They had to order a part. They picked it up today and Dealer had to replace a vacuum seal that wasn’t getting fully closed. However, they ran another diagnostic and got another error. I’m without a truck the next few days which is inconvenient but I just want the problem(s) fixed.

Thanks for the advice guys.

Engine light came back on at 1000 miles. Took it back in. Now saying an evap issue. Have to wait on a part. Hoping this isn’t going to be the norm. Gas mileage is no where near advertised so far either.

Did they give you a code?

Gas mileage is no where near advertised so far either.

It never is, specially with Ram. The test vehicle on the window sticker is a 2wd Tradesman with 3.21 gearing. You have an opposite end of the spectrum 4x4 with knobby tires and 3.92

Mine had the CEL come on for the evap system also. They said there was some update for it. They did the update and sent me on my way in about 15 minutes. I haven't had the CEL come on again, so hopefully all good. I'm currently at about 6k miles.

Said it was a code for evap purge valve Replaced it Still throwing a code. Now they had to put in a star request.

They are stumped at the moment.

Replacing the fuel pump. They worked through ab unch of stuff with the STAR folks. We shall see, the plan is to get it back after Christmas.

Good luck. Hopefully they figured it out.

Update: Got it back on New Years Eve. According to the dealership, they identified that there are rams that were built and installed with a fuel pump valve that is incorrect.
