Body PASSENGER CARTransmission Automatic 4-spd

The 1991 Nissan 240SX is a compact passenger car built on the N platform, powered by a 3.4‑quart engine that requires 5W‑30 API SM oil. With an automatic four‑speed transmission, it delivers EPA ratings of 18 mpg city, 25 mpg highway, and 21 mpg combined. Reliability data for the 19901998 range show only nine owner complaints overall, with seat belts as the most frequent issue and a single recall, placing the 1991 model in the lower‑complaint spectrum of its generation. This modest complaint count suggests a relatively dependable entry in the 240SX lineage.

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 model year represents a significant improvement in consumer complaints compared to the preceding 1990 model, dropping from 47 complaints to just 9, though it maintains the same single recall count and actually increases investigations from two to three. While complaints remain low throughout the early 1990s—registering only 16 in both 1992 and 1993 before plummeting to 2 in 1994—the 1991 model sits at the beginning of this stable period, predating the dramatic spike to 76 complaints seen in 1995. Notably, the 1991 model recorded zero crash or fire complaints, with the four seat belt-related issues representing the largest single complaint category, though the data does not specify the root cause of these reported problems. Despite the low complaint volume, the three investigations tied to 1991 exceed those of most surrounding years except 1990, suggesting potential safety scrutiny that did not translate into widespread owner reports. Given its substantially lower complaint count compared to 1990 and 1995, combined with the absence of crash or fire incidents in the federal record, 1991 emerges as a relatively favorable year within this generation for used car consideration.
