Subaru Ascent: A Comprehensive Buyer's Guide

Introduction

The Subaru Ascent is a mid-size three-row SUV produced by Subaru since 2018. It represents Subaru's return to the three-row SUV market after the discontinuation of the Tribeca in 2014. Designed for families needing more space and towing capacity than the Outback or Forester, the Ascent offers a blend of Subaru's signature all-wheel drive system, practicality, and a comfortable ride. It targets buyers who appreciate the brand's reputation for safety, longevity, and capability, while also demanding the space and features of a modern family SUV.

The Ascent fills a crucial role in Subaru's lineup, competing with vehicles like the Honda Pilot, Toyota Highlander, Ford Explorer, and Kia Telluride. Its distinctive styling and focus on all-weather capability distinguish it within the competitive mid-size SUV segment.

Generations

  • First Generation (2019 - Present)
    • 2019-2022: Initial production run featuring the 2.4L turbocharged Boxer engine. Standard EyeSight driver assist technology. Available in Base, Premium, Limited, and Touring trims. Initial model years saw some transmission software refinements and concerns regarding excessive oil consumption (addressed by later software updates and component revisions).
    • 2023-Present: Facelifted design with updated front and rear styling, including redesigned headlights and taillights. Enhanced EyeSight system with wider field of view. Improved infotainment system with wireless Apple CarPlay and Android Auto. Further refinements to address earlier reliability concerns. The Onyx Edition trim gains more popularity.

Reliability & Common Issues

The Subaru Ascent, particularly in its earlier years, has faced some reliability challenges. While Subaru has worked to address these issues, potential buyers should be aware of them.

Engine (2.4L Turbocharged Boxer)

  • Oil Consumption: Some early Ascent models (2019-2020) experienced excessive oil consumption. This was often attributed to a combination of factors, including piston ring issues and software calibration impacting oil dilution. Subaru issued a technical service bulletin (TSB) and offered software updates to mitigate this. However, in severe cases, engine component replacements were necessary. Checking oil levels regularly is crucial for these earlier models. Later models (2021+) have shown significant improvements.
  • Turbocharger Issues: While less common than oil consumption, some owners have reported turbocharger failures. This can manifest as a loss of power, unusual noises, or check engine lights. Proper maintenance, including regular oil changes, can help extend the life of the turbocharger.
  • Direct Injection Carbon Buildup: As with many direct-injection engines, carbon buildup on the intake valves is a potential long-term concern. Consider periodic intake valve cleaning (walnut blasting) as preventative maintenance, especially on higher-mileage vehicles.

Transmission (CVT)

  • Software Glitches: The Ascent utilizes a Lineartronic CVT (Continuously Variable Transmission). Early models experienced some transmission software glitches that could lead to hesitation, jerky acceleration, or unusual noises. Subaru released software updates to address these issues, and these updates are generally recommended for earlier models.
  • CVT Longevity: While generally reliable, CVTs can be more sensitive to maintenance than traditional automatic transmissions. Regular CVT fluid changes (every 30,000-60,000 miles, depending on driving conditions) are crucial for longevity. Using the correct Subaru CVT fluid is also essential.

Other Potential Issues

  • Infotainment System: Early Ascent models sometimes suffered from infotainment system glitches, including slow response times, frozen screens, and Bluetooth connectivity issues. Subaru released software updates to improve the system's performance. The updated infotainment system in the 2023+ models represents a significant improvement.
  • EyeSight System: The EyeSight driver-assist system relies on cameras and sensors, which can be affected by dirt, snow, or obstructions. Ensure that the windshield is clean and free of debris in front of the cameras. Software updates are also important to ensure optimal system performance.
  • Battery Drain: Some owners have reported issues with battery drain, especially if the vehicle sits unused for extended periods. Proper battery maintenance and ensuring all accessories are turned off can help prevent this.

Important Note: A thorough pre-purchase inspection by a qualified mechanic is highly recommended, especially for earlier Ascent models. Checking service records to verify that any relevant TSBs or recalls have been addressed is also crucial.

Driving Experience

The Subaru Ascent provides a comfortable and confident driving experience, particularly in inclement weather. Its strengths include:

Pros

  • All-Wheel Drive: Subaru's symmetrical all-wheel drive system provides excellent traction and stability in various conditions, including snow, rain, and gravel.
  • Comfortable Ride: The Ascent offers a smooth and comfortable ride, even on rough roads.
  • Spacious Interior: The interior is spacious, with comfortable seating for up to eight passengers. The third-row seating is usable for adults on shorter trips.
  • Standard Safety Features: The EyeSight system is standard on all trims and includes features like adaptive cruise control, lane departure warning, and automatic emergency braking.
  • Towing Capacity: With a towing capacity of up to 5,000 pounds, the Ascent can handle trailers, boats, and other recreational equipment.

Cons

  • Fuel Economy: Fuel economy is adequate but not class-leading.
  • CVT Transmission: While the CVT is generally smooth, some drivers may find it less engaging than a traditional automatic transmission. The engine can sometimes drone under heavy acceleration.
  • Engine Noise: The 2.4L turbocharged engine can be somewhat noisy, especially under acceleration.
  • Early Model Reliability: As noted above, earlier models had some reliability issues that should be considered.

Overall, the Ascent provides a practical and comfortable driving experience, particularly for families who prioritize safety, all-weather capability, and interior space.

Buying Advice

When considering a used Subaru Ascent, keep the following in mind:

Years to Look For

  • 2021-Present: These model years generally exhibit improved reliability compared to the earlier models. Subaru addressed many of the initial concerns regarding oil consumption and transmission performance.
  • 2023-Present: The facelifted models offer updated styling, an improved infotainment system, and enhanced safety features.

Years to Avoid (or Be Extra Cautious With)

  • 2019-2020: These model years are more prone to oil consumption issues. Thoroughly inspect the vehicle's service records and check for any TSBs or recalls that have been addressed. Consider a pre-purchase inspection by a qualified mechanic to assess the engine's condition.

Key Considerations

  • Service Records: Always review the vehicle's service records to ensure that it has been properly maintained. Pay particular attention to oil changes and CVT fluid changes.
  • Pre-Purchase Inspection: A pre-purchase inspection by a qualified mechanic is highly recommended, especially for earlier models. This will help identify any potential issues before you buy the vehicle.
  • Test Drive: Take the vehicle for a thorough test drive, paying attention to engine performance, transmission smoothness, and any unusual noises or vibrations.
  • Oil Level: Check the oil level regularly, especially on earlier models.
  • Trim Level: Consider your needs and budget when choosing a trim level. The Premium and Limited trims offer a good balance of features and value.

By following these tips, you can increase your chances of finding a reliable and enjoyable Subaru Ascent that meets your needs.
