No crank, lights work, then it suddenly starts

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2024 Ram 1500 catch play that a wheels-hanging inspection misses. If the cheap test changes it, stop and reassess. I'd want that in writing, not as a promise. I'd sleep better after that step, even if it finds nothing. I'd rather pay for diagnosis than a second guess-repair.

Log the conditions before you spend. Write temp, speed, and in-gear vs coast when the 2024 Ram 1500 does it — then decide on parts. That's the branch I'd chase this week. On “no crank, lights work, then it suddenly,” that was the fork that mattered for me. I'd want that in writing, not as a promise. I keep a notes app thread for this now.

Start with the test that can prove you wrong. Move a coil or plug on the 2024 Ram 1500 if it's cylinder-specific and see whether the code follows. That's the branch I'd chase this week. If they can't show the line item, I assume it's hiding. Worth doing even if the car feels fine right now. No warning lights, which is why I'm documenting it.

If it were in my driveway, get a real battery/charging test on the 2024 Ram 1500, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. Have you gotten a second quote in writing? This is the version I'd tell a friend.

I wouldn't throw parts yet. Loaded-suspension checks on the 2024 Ram 1500 catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. If they can't show the line item, I assume it's hiding. Worth doing even if the car feels fine right now. Next check is the cheap one I can do in a driveway.
