2023 Nissan Z — dealer cannot reproduce an intermittent warning

HighwayDetailer589Community StarterOct 27, 20252023 Nissan Z PerformanceSacramento
2023 Nissan Z Performance, about 40,000 miles. I have brought the car in twice for the same intermittent warning and both visits ended with could-not-reproduce. I have video and timestamps. What is the best way to build a useful paper trail? I am in Sacramento. What would you check next?

I'd keep this practical. Verify the cheap/easy branch on the 2023 Nissan Z before a big repair or a big spend. That's where I'd start. No need to make it theatrical. I'll update if anything new shows up.

Write down what you already tried. A second data point from another 2023 Nissan Z owner helps more than a generic diagnosis. I'd do that before spending real money. This is from a 2023 Nissan Z in Sacramento with 40,000 miles. Happy to compare notes if your setup is different. Might be overthinking it, but I'd rather overthink than overspend.

Useful. I'll report back after I verify that on my 2023 Nissan Z. If the story changes I'll post the new data.

Owner notes beat generic advice here. On the 2023 Nissan Z in Sacramento, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “dealer cannot reproduce an intermittent warning,” that was the fork that mattered for me. If it doesn't change the out-the-door or the repair estimate, it's noise. This is the filter I use when the thread starts repeating itself. Wrote this up on my lunch break.

This is from a 2023 Nissan Z in Sacramento with 40,000 miles. Not gospel, but it saved me a headache. I've seen both outcomes, which is why I'd test instead of assume. I'll update if anything new shows up.

I parked the 2023 Nissan Z and wrote down what I already tested so I'm not repeating myself. I'd rather look cautious in this thread than stuck later.

Write down what you already tried. A second data point from another 2023 Nissan Z owner helps more than a generic diagnosis. That's where I'd start. Time, temperature, and whether it's in gear are the notes that actually help a shop. If this is nothing, great. I want that in data.

Don't overfit one forum story to your car. If it still isn't clear on the 2023 Nissan Z, a specialist hour can be cheaper than another round of parts. That's where I'd start. Was this after sitting overnight? That's coming from doing this as an owner, not a shop. If the story changes I'll post the new data.

Agree — and I'd add this: A second data point from another 2023 Nissan Z owner helps more than a generic diagnosis. Then you'll know the next fork. That's the sequence I'd use. Not trying to scare you — just skip the expensive first guess. If this is nothing, great. I want that in data.
