2013 Infiniti G37 — what changed after 100k miles?

BrakeGuy46Community StarterAug 27, 20262013 Infiniti G37 xSNorthern Virginia
The car has crossed 100k and still drives well. I want to stay ahead of age-related failures instead of waiting for roadside problems. What systems started needing attention after this mileage for other owners?

Don't overfit one forum story to your car. If it still isn't clear on the 2013 Infiniti G37, a specialist hour can be cheaper than another round of parts. That's where I'd start. This is from a 2013 Infiniti G37 in Northern Virginia. Stop there until you know. I'm in no rush to be a hero on it.

Owner notes beat generic advice here. On the 2013 Infiniti G37 in Northern Virginia, I'd fix the thing you'll notice every day before chasing spec-sheet extras. Then you'll know the next fork. On “what changed after 100k miles,” that was the fork that mattered for me. If it doesn't change the out-the-door or the repair estimate, it's noise. Wrote this up on my lunch break.

I'd keep this practical. Verify the cheap/easy branch on the 2013 Infiniti G37 before a big repair or a big spend. I'd do that before spending real money. No need to make it theatrical. Doing the boring step first on purpose.

Write down what you already tried. A second data point from another 2013 Infiniti G37 owner helps more than a generic diagnosis. I'd do that before spending real money. That's the whole play. If this is nothing, great. I want that in data.

I hear you, though I'd still want a second check. A second data point from another 2013 Infiniti G37 owner helps more than a generic diagnosis. Then you'll know the next fork. Verbal 'we'll take care of it' is not a plan. I'd rather be boring and correct. This is the version I'd tell a friend.

Not convinced that's the whole story. If it still isn't clear on the 2013 Infiniti G37, a specialist hour can be cheaper than another round of parts. That's where I'd start. Write the result down so the next test isn't a repeat of the last one. I'm in no rush to be a hero on it.
