1994 Cadillac Seville

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1994 Seville.

Transmission Automatic 4-spd

The 1994 Cadillac Seville is the 1994 model-year entry in Cadillac’s Seville line, delivered with a four-speed automatic transmission and EPA fuel-economy ratings of 15 city, 23 highway, and 18 combined mpg; routine servicing calls for 7.5 quarts of 5W-30 API engine oil. Owner records show 62 complaints for this year, with engine and engine-cooling issues flagged as the top area and two recalls on file. Within the broader 1990–2004 Seville complaint history—where volume peaked at 131 in 1996 and fell to 17 in 2004—the 1994 model sits below the worst year but well above the best, marking it as a mid-pack year rather than a reliability standout.

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 100,000 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.

From 1990 to 1993 the Cadillac Seville’s complaint count rose steadily from 23 to 46, while recalls remained low (0‑2) and investigations were rare. In 1994 complaints jumped to 62, recalls held at two, and investigations increased to two, marking the beginning of a sharper upward trend that peaked in 1996 with 131 complaints and four investigations. Recall frequency stayed relatively flat across the generation (mostly 0‑2 per year), but investigations grew after 1993 before fluctuating between one and four annually. Technical service bulletins were minimal through the mid‑1990s (13 in 1994) and only began to climb dramatically after 1999. Overall, 1994 sits on the rising side of the complaint curve, with average recall activity but a noticeable increase in reported problems, suggesting that a well‑inspected example could be acceptable but buyers should anticipate a higher likelihood of issues compared with earlier model years.
