When does it fail?
Of the 7 electrical complaints filed for the 2013 INFINITI G37, here's the actual mileage breakdown — failures cluster heaviest at 25,000-50,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
No new NHTSA electrical complaint has been filed on this vehicle in over 8 years — the issue may be aging out of the active population.
