2024 Jeep Gladiator — second battery versus portable power station — New Jersey owner question

It did second battery versus portable power station — twice this week, both times after sitting. No change in mileage feel. If it repeats twice more I'll book time.

This is usually cheaper to test than to guess. Swap the cheap/easy piece first on the 2024 Jeep Gladiator and see if the fault moves. If the cheap test changes it, stop and reassess. A shop burned me once by skipping that step. Not interested in a five-hour wait for a shrug.

Log the conditions before you spend. Loaded-suspension checks on the 2024 Jeep Gladiator catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. On “second battery versus portable power station —,” that was the fork that mattered for me. I'd want that in writing, not as a promise. This is the filter I use when the thread starts repeating itself. Next check is the cheap one I can do in a driveway.

If it were in my driveway, write temp, speed, and in-gear vs coast when the 2024 Jeep Gladiator does it — then decide on parts. You'll know quickly if you're on the wrong tree. Had a similar mess a couple years ago and that's what finally sorted it. Trying not to diagnose from the couch.

Ask what changed right before it started. Move a coil or plug on the 2024 Jeep Gladiator if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. Any freeze-frame data saved? I'm in no rush to be a hero on it.
