Engine alert at 500 miles ! P301

[ScottyMac]

I’ve had my 2025 V6 Bighorn 1500 for 8 days… 500 miles and today my engine light goes on… P301 code and another multi mos fire code… I’m learning a little more each search for this … Anyone know what’s going on with this? Widespread… ?

I have a 2025 Tradesman V6 that I drove off the lot on 3/21/25. The check engine light came on at 478 miles. The dealership said it had P0300 misfires showing, reset it and test drove with no issues. The light came back at on at 843 miles. Took it to the dealership, who had it for two days, and they did a cam/ crank "relearn" on it and sent the "flight data" to Stellantis for review. No further issues so far.

Mine had misfires when it was new. Similar story to you 2025 guys. CEL comes on, misfire code, reset by disconnecting battery method. Happened again soon after, lather rinse repeat. Now havent had a misfire in almost 6 years.

Take it to dealer. A lot of posts about needing software update to correct the issue on 2025s

Well, 80 miles after the last incident the light is back on. It's only happening when I remote start it. Twice using the phone app and once using the key fob. Back to the dealership it goes

Was just told., “ needs a software update”, Stellantis still working on it still … Enough people are dealing with this now to make this a “ major” recall issue
