1995 Infiniti Q45

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1995 Q45.

Transmission Automatic 4-spd

The 1995 Infiniti Q45 is a full‑size luxury sedan equipped with an automatic four‑speed transmission and a 6.3‑quart oil capacity that uses 5W‑30 or 10W‑30 API SM viscosity oil, while its EPA fuel‑economy ratings sit at 15 mpg city, 20 mpg highway, and a combined 17 mpg. Across the 1990‑2006 production span the model’s complaint volume peaked in 1991 with 47 reports, but by 1993 the tally had dropped to just two, and the 1995 year recorded only eight owner complaints overall, the most frequent being vehicle‑speed‑control issues, with no recalls issued. This places the 1995 Q45 toward the lower‑end of the model’s reliability curve, indicating a relatively stable and dependable iteration within the line’s history.

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 first-generation Q45 (1990–1996) experienced its highest complaint volumes and recall activity in the early years, with 1991 peaking at 47 complaints, 2 recalls, and 3 investigations. After a brief lull in 1993 (just 2 complaints), 1994 saw a resurgence to 36 complaints, though no recalls. The 1995 model year then marks a sharp decline to only 8 complaints, zero recalls, and zero investigations—a trend that continues into 1996. This places 1995 at the mature, refined end of the generation’s arc, with a notably clean federal record compared to its predecessors. While the data does not specify root causes, the top complaint area of vehicle speed control (5 complaints) and the presence of 3 crash complaints warrant a focused pre-purchase inspection of those systems. Overall, the 1995 Q45 appears to be a strong candidate within the first generation, offering a low-risk ownership proposition based on its minimal reported issues.
