1991 Hyundai Scoupe

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 Scoupe.

Body PASSENGER CARTransmission Automatic 4-spd

The 1991 Hyundai Scoupe is a passenger‑car that employs a modest powertrain holding 3.6 qt of oil, lubricated with 20W‑40, 20W‑50 or 10W‑30 API grades, and mated to an automatic four‑speed transmission. Its EPA fuel‑economy ratings stand at 22 mpg city, 29 mpg highway and 25 mpg combined. In its debut year the model accumulated 25 total owner complaints, with power‑train issues comprising the majority, and no recalls were issued. This places the 1991 example at the start of a five‑year span that saw complaints rise to a peak of 31 in 1994 before falling to 7 in 1995, suggesting a gradual improvement in reliability for later model years.

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; 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 1991 the Hyundai Scoupe recorded 25 complaints, with no recalls but one investigation and nine TSBs, placing it at the top of the five‑year window in terms of complaints. The following year, 1992, saw a sharp decline to eight complaints, while 1993 and 1994 rose again to 20 and 31 respectively, indicating a volatile complaint trend rather than a steady decline. Across the 1991‑1995 span, recalls remained absent, and investigations were consistently one per year, suggesting no systemic safety overhauls. The 1991 model’s complaint mix—power train (5), engine & cooling (5), visibility (3), and structure (3)—shows a concentration on mechanical and structural issues, but no fire or crash complaints were reported. Given the high complaint count and the fact that later years did not improve the overall trend, 1991 is a less favorable year to buy, as it sits at the peak of reported issues within this generation.
