2013 Infiniti G37 — infotainment became glitchy after an OTA update

I wouldn't throw parts yet. 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. Not gospel, but it saved me a headache. Parking it somewhere I can hear it better next time.

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. Don't erase codes until someone who can help has seen them. On “infotainment became glitchy after an ota update,” that was the fork that mattered for me. This is from a 2013 Infiniti G37 in California. That's the sequence I'd use. I'm keeping receipts and dates in one folder.

I'd want a measurement, not a hunch. 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. This is from a 2013 Infiniti G37 in California. Take it or leave it — that's what I'd do. Not trying to scare you — just skip the expensive first guess. If that fails I'll eat the diagnostic fee.

I wouldn't throw parts yet. Get a real battery/charging test on the 2013 Infiniti G37, not just resting voltage, before blaming a module. 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.

This is usually cheaper to test than to guess. Swap the cheap/easy piece first on the 2013 Infiniti G37 and see if the fault moves. That's the branch I'd chase this week. Verbal 'we'll take care of it' is not a plan. Not driving it hard until I know more.
