Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter at 7,500 mi; spark plugs every 60,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 1991 Nissan NX recorded 7 complaints and 1 recall, matching the 1992 model's single recall but with one fewer complaint than the following year (8 complaints). The 22 TSBs remained constant across both model years, suggesting no significant escalation in manufacturer-issued service bulletins. Seat belts emerged as the primary complaint area (3 instances), followed by engine and engine cooling concerns (2), while crash-related complaints numbered 2 and fire complaints totaled 1. Given that 1991 sits at the lower end of the complaint arc with fewer issues than 1992, it represents the slightly more favorable vintage within this limited two-year window. However, the presence of fire and crash complaints, even at low volumes, warrants a thorough pre-purchase inspection, particularly of seat belt and engine components.
