Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 24F · 585 CCA battery, OE oil filter 1520865F0E. Note the factory front wiper blades is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

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 30,000 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 1999 Infiniti G20 marks a notable shift in the federal record for this generation, particularly in the context of its immediate predecessors and successors. Complaints dropped sharply from the 1995 peak of 29 to just 7 in 1999, aligning with the lowest levels seen in 1994 and later years (2001–2002), while recalls fell to zero—unlike the consistent 1–2 recalls annually from 1991 to 1996. The absence of investigations and a relatively high number of technical service bulletins (54) suggest Nissan addressed issues proactively through TSBs rather than formal recalls. Compared to the 2000–2002 models, the 1999 G20 shows no red flags in crash or fire complaints, and its top complaint areas (seats, steering, electrical, and lighting) are minor in volume. This year sits in a stable, low-complaint phase of the generation, implying improved reliability. **Takeaway: The 1999 G20 is a strong used purchase, as it avoids the higher complaint rates of earlier years while benefiting from matured engineering and no recalls.**
