2019 Ram 2500 — delayed engagement into Drive when cold

OP update: scanned the 2019 Ram 2500 again and still only have the one pending code, no new lights. If that fails I'll eat the diagnostic fee.

Ask what changed right before it started. Get a real battery/charging test on the 2019 Ram 2500, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. Time, temperature, and whether it's in gear are the notes that actually help a shop. A day of patience here is cheaper than a wrong part. Happens in gear, not in park, for what that's worth.

If it were in my driveway, if a shop can't duplicate it on the 2019 Ram 2500, bring a video plus freeze-frame data, not just a story. That's the branch I'd chase this week. This is from a 2019 Ram 2500 in Nashville. Post the numbers (or the code) and people can get more specific. If it repeats twice more I'll book time.

Start with the test that can prove you wrong. Capture voltage while the 2019 Ram 2500 is actually failing — after it restarts you've lost the clue. Don't erase codes until someone who can help has seen them. No need to make it theatrical. If that fails I'll eat the diagnostic fee.

If it were in my driveway, two 2019 Ram 2500s can feel identical and have different causes, so measure before you copy someone else's repair. If the cheap test changes it, stop and reassess. If they can't show the line item, I assume it's hiding. Heat soak after errands is the other window.

Log the conditions before you spend. Capture voltage while the 2019 Ram 2500 is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. On “delayed engagement into drive when cold,” that was the fork that mattered for me. Time, temperature, and whether it's in gear are the notes that actually help a shop. I keep a notes app thread for this now.

This is usually cheaper to test than to guess. Get a real battery/charging test on the 2019 Ram 2500, not just resting voltage, before blaming a module. Save the big job until that test fails. If it doesn't change the out-the-door or the repair estimate, it's noise. I'd rather look cautious in this thread than stuck later.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2019 Ram 2500 and see if the fault moves. You'll know quickly if you're on the wrong tree. That's the whole play. Trying not to diagnose from the couch.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2019 Ram 2500 is losing coolant with no puddle. Save the big job until that test fails. Run the total, not the monthly, before you commit. I'd rather be boring and correct. I'd rather look cautious in this thread than stuck later.

It did delayed engagement into drive when cold twice this week, both times after sitting. No change in mileage feel. Video is ugly but it shows the hesitation.

If it were in my driveway, loaded-suspension checks on the 2019 Ram 2500 catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. Was this after sitting overnight? I'd rather be boring and correct. Video is ugly but it shows the hesitation.

I wouldn't throw parts yet. Move a coil or plug on the 2019 Ram 2500 if it's cylinder-specific and see whether the code follows. That's the branch I'd chase this week. This is from a 2019 Ram 2500 in Nashville. Write the result down so the next test isn't a repeat of the last one. Only after sitting overnight so far.

That's the whole play. Your commute and mine probably aren't the same, but the test still applies. Parking it somewhere I can hear it better next time.

I'm keeping receipts and dates in one folder.
