Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 Eclipse 2.4L.

Body PASSENGER CAREngine 2.4LTransmission Automatic (S4)

The 2001 Mitsubishi Eclipse 2.4L is a passenger‑car equipped with a 2.4‑liter engine that takes 4.5 quarts of 10W‑30 or 5W‑30 API oil and is paired with an S4‑speed automatic transmission, delivering EPA‑rated fuel economy of 18/25/20 mpg. Owner records for the year show 316 complaints, with wheels cited as the top problem area and the vehicle subject to 13 recalls. Compared with the Eclipse’s complaint history from 1990 to 2012—where 1995 recorded the highest at 392 complaints and 2011 the lowest at just one—the 2001 total situates the model toward the better‑end of the reliability range, indicating fewer issues than the worst years but more than the best‑recorded year.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 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.

In the federal record, 2001 records 316 complaints, 13 recalls, 2 investigations and a total of 167 TSBs, figures that exceed the 2000 totals of 314 complaints, 10 recalls, 3 investigations and 140 TSBs but are far lower than the 1995 peak of 392 complaints. The complaint trajectory shows a steep rise through the mid‑1990s, a gradual decline to the low‑hundreds by 1999, then a secondary spike at 2000‑2001 before dropping dramatically to 104 complaints in 2002. The 2001 model’s top complaint categories — Wheels (96), Power Train (27), Air Bags (27) and Structure (22) — account for the majority of the 316 reports, indicating recurring issues in those systems. Compared with the surrounding years, 2001 sits at the tail of a brief high‑complaint interval, with recall activity (13) higher than the immediate post‑model year 2002 (4) but comparable to the earlier 2000 level (10). Because the 2001 Eclipse carries above‑average complaint and recall counts relative to later model years, a buyer should weigh these data points carefully and may find a later‑model example more reliable.
