The 1991 Mazda 626 is a midsize family sedan (also sold as a coupe in some markets) aimed at drivers who want a practical commuter with a more “driver-focused” feel than many rivals of the era. It sits in the mainstream midsize segment against cars like the Honda Accord, Toyota Camry, and Nissan Stanza/Altima, often priced competitively when new. For 1991, the 626 continued in the GD generation (late-1980s/early-1990s design), known for tidy handling, straightforward controls, and efficient packaging. Today it’s ideal for budget-minded owners who value simplicity and are comfortable staying on top of age-related maintenance.

- Engine choices: Many 1991 Mazda 626 models came with a 2.2L inline-4 as the core engine, with a 2.0L inline-4 offered in some trims/markets. Both are designed for everyday drivability and reasonable fuel economy for the period. - Available manual or automatic transmissions: A manual transmission is often preferred by enthusiasts for its direct feel, while the automatic suits daily commuting; either can be durable if serviced properly. - Practical midsize cabin and trunk: The 626 is sized for real adult rear-seat space and family-duty use, with a trunk that works well for groceries, luggage, and daily errands. - Road manners: Compared with many early-1990s midsize sedans, the 626 has a reputation for predictable handling and confident steering, making it feel lighter on its feet than some competitors. - Straightforward serviceability: Many maintenance tasks are conventional for the era (belts, hoses, ignition service), which can help keep ownership costs manageable when the car is maintained proactively.

Shoppers searching “1991 Mazda 626 reliability” will find that these cars can be dependable, but most problems today stem from age, deferred maintenance, and heat cycles rather than inherent design flaws. The most common “1991 Mazda 626 problems” and “1991 Mazda 626 common issues” reported by long-term owners include: - Automatic transmission wear and shifting issues: Some owners report harsh shifting, slipping, or delayed engagement, often showing up around 120,000–180,000 miles, especially if fluid changes were skipped. A simple fluid and filter service can help when caught early, but neglected units may need rebuilding. - Cooling system leaks and overheating: Aging radiators, thermostat housings, and rubber hoses can seep or fail, leading to overheating—often in the 100,000+ mile range or simply with old components. Overheating can snowball into head gasket problems if ignored, so temperature spikes should be treated as urgent. - Oil leaks and consumption: Valve cover gasket leaks are common on older 626 engines, sometimes appearing as oil smell or seepage onto the engine. Higher-mile engines may also consume oil between changes; checking level regularly helps prevent low-oil damage. - Electrical and idle/driveability quirks: Intermittent sensors, vacuum leaks, or aging ignition components can cause rough idle, stalling, or hesitation, especially as the car passes 150,000 miles. Many issues are repairable with careful diagnosis, but “parts cannon” repairs can get expensive if troubleshooting is sloppy.
