2013 Infiniti G37 — clutch engagement changed after a long traffic commute

I wouldn't throw parts yet. Write temp, speed, and in-gear vs coast when the 2013 Infiniti G37 does it — then decide on parts. You'll know quickly if you're on the wrong tree. If they can't show the line item, I assume it's hiding. I'll poke at it this weekend.

Log the conditions before you spend. Two 2013 Infiniti G37s can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. On “clutch engagement changed after a long traffic,” that was the fork that mattered for me. This is from a 2013 Infiniti G37 in Detroit with 70,500 miles. Verbal 'we'll take care of it' is not a plan. I'll poke at it this weekend.

Start with the test that can prove you wrong. Two 2013 Infiniti G37s 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. Do that first. I've seen both outcomes, which is why I'd test instead of assume. Not interested in a five-hour wait for a shrug.

If it were in my driveway, move a coil or plug on the 2013 Infiniti G37 if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. Had a similar mess a couple years ago and that's what finally sorted it. I'd sleep better after that step, even if it finds nothing. I'd rather pay for diagnosis than a second guess-repair.

Intermittent stuff lies if you only catch it once. Get a real battery/charging test on the 2013 Infiniti G37, not just resting voltage, before blaming a module. Save the big job until that test fails. On “clutch engagement changed after a long traffic,” that was the fork that mattered for me. When does it actually happen? I keep a notes app thread for this now.

Tried a second charger / second scan and the story on the 2013 Infiniti G37 didn't change. Next check is the cheap one I can do in a driveway.

I'd want a measurement, not a hunch. Swap the cheap/easy piece first on the 2013 Infiniti G37 and see if the fault moves. You'll know quickly if you're on the wrong tree. I'd want that in writing, not as a promise. Checking again after work.

Intermittent stuff lies if you only catch it once. Capture voltage while the 2013 Infiniti G37 is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. On “clutch engagement changed after a long traffic,” that was the fork that mattered for me. Verbal 'we'll take care of it' is not a plan. I'll poke at it this weekend.

This is usually cheaper to test than to guess. Write temp, speed, and in-gear vs coast when the 2013 Infiniti G37 does it — then decide on parts. Save the big job until that test fails. That's the whole play. Checking again after work.
