Overview: what this guide covers

• Quick model summary: The Impreza (2017–2023) is built on Subaru’s global platform with all-wheel drive as a common feature. It uses a 2.0-liter flat-four engine (FB20) paired with either a Continuously Variable Transmission (CVT) or, in some trims/years, a traditional manual transmission. AWD is standard on most trims.
• Why reliability matters: Routine maintenance and timely repairs are the most reliable predictor of long-term ownership satisfaction. The guide focuses on maintenance practices, known wear-items, and budgeting for typical 2025 costs.

Key reliability themes for the Impreza (2017–2023)

• Drivetrain and transmission
  • Transmission choices: CVT is common across many trims; some variants offered a manual option in certain years/grades.
  • General CVT reliability guidance: CVTs can be very durable with proper maintenance but require correct fluid and service intervals. Avoid aggressive towing or heavy loads beyond spec, and follow Subaru’s service intervals for CVT fluid replacement.
  • Regular CVT maintenance is important because CVT failures can be expensive to repair or replace. If you notice shudder, slipping, delayed engagement, or unusual noises, have the transmission inspected promptly.
• Engine and cooling
  • Engine: 2.0-liter FB20 boxer engine is built for efficiency and smooth operation. Routine maintenance is the best defense against premature wear.
  • Oil consumption: While not unique to this engine, some Subaru engines have been known to consume oil at higher-than-average rates. Regular oil level checks are prudent, especially if the vehicle is older or has higher mileage.
  • Cooling system: Maintain thermostat, radiator hoses, and coolant levels to prevent overheating, which can impact long-term reliability.
• All-wheel drive and chassis
  • AWD components rely on regular service intervals (differentials, transfer case if applicable) and proper tire maintenance to prevent uneven wear and drivetrain stress.
  • Suspension components (struts, ball joints, bushings) wear with time and mileage, especially in regions with rough roads or frequent winter driving.
• Brakes and tires
  • Brakes wear at a rate influenced by driving style and tire type. AWD cars can wear tires a bit differently due to grip needs; alignments and tire rotations are important.
• Electrical and interior
  • Infotainment and electrical components in Subarus are generally reliable, but like any modern vehicle, occasional software updates or component replacements may be required over time.
• How to maximize reliability
  • Stick to the maintenance schedule, address issues early, and use quality parts (OEM or reputable equivalents).
  • Keep tires evenly worn and properly inflated; rotate regularly to balance wear.
  • Use the correct grade of fluids (engine oil, CVT fluid, brake fluid) and follow Subaru’s service specs.
