Honda N-ONE common problems: what to check before you buy
Credov's researched list of the 4 faults the Honda N-ONE is known for (2011–2015), 3 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
Known problems on the Honda N-ONE

What to look for: Listen for a clunk and feel for lost drive when accelerating briskly from a stop in Drive and Reverse.
Why it matters: Honda Japan filed three times on this shaft. The failure end point is stated plainly: the shaft breaks and the car cannot be driven. Because the Japanese remedy was conditional - reflash if the recorded load was inside limits, new transmission if not - a car that was only reflashed can still have an already-loaded shaft, so the driving symptoms matter as much as the campaign paperwork.
What to look for: Listen for an uneven idle from cold, and feel for a stumble or hesitation when you press the accelerator hard.
Why it matters: The noise-suppression resistor inside the coil can go open circuit from arcing. Honda Japan says the car can run rough with the engine lamp lit and, at worst, the engine can stop - either because the coil output collapses or because ignition noise stops the engine computer controlling properly.
What to look for: Check the engine restarts with one clean crank every time idle-stop cuts it, with no grinding or stalling.
Why it matters: The notification records 269 cases. The engine computer could overwrite its own starter and airflow data as the engine shut down, after which the engine may not restart at all, or the starter motor turns intermittently and damages itself. The Japanese remedy was a reflash plus inspection and replacement of a damaged starter, so a car that was only reflashed can still be carrying a worn starter.
What to look for: Look in the driver's door frame near the latch for small numbered recall stickers, and photograph each one.
Why it matters: Every Japanese recall schedule in this overlay ends with the same line: completed vehicles get a sticker bearing the campaign number near the driver's-side door striker. Nothing in a New Zealand recall lookup covers Japanese campaign numbers, so for an import this sticker cluster is often the only outstanding-work evidence physically on the car.
