Overview
The 1991 Oldsmobile Cutlass is a midsize, front-wheel-drive family car sold primarily as the Cutlass Supreme (coupe and sedan) and Cutlass Cruiser (wagon), positioned between basic compacts and larger full-size sedans. It’s a comfortable, traditional American daily driver with a smooth ride, simple controls, and a strong emphasis on value. For 1991, the Cutlass Supreme continued in its late-1980s W-body generation, offering familiar styling and proven mechanicals rather than a ground-up redesign. It’s ideal for buyers who want a classic GM feel, easy parts availability, and straightforward ownership—provided they stay ahead of age-related maintenance.
Key Features
1) Front-wheel-drive W-body platform: Known for a stable highway ride, predictable handling, and roomy cabin space for a midsize footprint.
2) Engine options (varies by trim/region): Many 1991 Cutlass Supreme models came with a 3.1L V6 (GM 60-degree V6 family), while some trims offered a 3.3L V6 for extra low-end torque. (Availability varies by body style and equipment package.)
3) 4-speed automatic transmission: Most were paired with a GM 4-speed overdrive automatic, helping drivability and cruising RPM compared to older 3-speeds.
4) Comfortable, feature-rich trims: Depending on options, you could find power windows/locks, cruise control, upgraded audio, tilt steering, and plusher seating—common reasons buyers chose Oldsmobile over more basic competitors.
5) Practical body choices: The Cutlass name in 1991 covered multiple needs, from the everyday Cutlass Supreme sedan/coupe to the Cutlass Cruiser wagon for families needing cargo space.
Common Issues & Reliability
Shoppers researching 1991 Oldsmobile Cutlass problems, 1991 Oldsmobile Cutlass reliability, and 1991 Oldsmobile Cutlass common issues should expect a generally durable drivetrain with several repeat trouble spots typical of early-1990s GM vehicles.
1) Intake manifold gasket leaks (3.1L/3.3L V6): A common complaint is coolant seepage or mixing due to failing intake gaskets, often showing up around 80,000–140,000 miles. Symptoms include unexplained coolant loss, overheating, sweet smell, or milky oil. If caught early, repairs are manageable; ignored, it can damage bearings.
2) Automatic transmission wear and shift issues: Many owners report harsh shifts, delayed engagement, or slipping as mileage climbs, commonly after 120,000+ miles depending on service history. Heat and neglected fluid changes are major contributors, so maintenance records matter.
3) Ignition and drivability faults: Misfires, rough idle, or stalling can stem from aging ignition components (coils, ignition module, plugs/wires) and vacuum leaks. These issues often surface in high-mileage cars and can be intermittent, making diagnostics important.
4) Aging electrical and interior components: Power window motors/regulators, door lock actuators, instrument cluster lighting, and HVAC control issues are frequent on vehicles of this age. These are usually more “annoyance” problems than catastrophic failures, but they affect day-to-day usability.
