2024 Subaru Forester: Reliability Ratings

Buying a car in its final production year before a major redesign is often a secret strategy used by the most reliability-conscious buyers. The 2024 Subaru Forester represents the culmination of the fifth generation (2019–2024). While the incoming 2025 model promises new technology and updated aesthetics, the 2024 model offers something arguably more valuable: a proven track record. This analysis breaks down the reliability ratings, engine longevity, and specific maintenance realities of the 2024 Forester.

The Advantage of the "Outgoing" Model

The automotive industry follows a cycle where the first year of a new generation often suffers from “teething issues.” Conversely, the final year is usually the most robust. The 2024 Forester benefits from five years of engineering corrections applied to the SK platform.

Specific issues that plagued the 2019 and 2020 models, such as glitches with the Thermo Control Valve (TCV) and early firmware bugs in the Starlink infotainment system, have largely been ironed out in the 2024 production run. When you buy this model year, you are buying the most refined version of this specific vehicle architecture.

Reliability Scores and Industry Data

The 2024 Forester consistently ranks high among compact SUVs for predicted reliability. Major automotive data organizations place it near the top of the segment, often trading blows with the Toyota RAV4 and Honda CR-V.

Consumer Reports and J.D. Power

Consumer Reports has historically given the fifth-generation Forester high marks. For the 2023 and 2024 model years, the Forester secured a “Recommended” status, scoring significantly higher than the class average in predicted reliability. This score is based on data from hundreds of thousands of members who own previous years of this generation.

J.D. Power rates the 2024 Forester favorably as well. In recent assessments for “Quality & Reliability,” the Forester typically scores in the 81-84 range (out of 100). This places it firmly in the “Great” category. Their data suggests fewer complaints per 100 vehicles regarding powertrain and mechanical fitment compared to domestic competitors like the Ford Escape or Jeep Compass.

RepairPal and Maintenance Costs

According to RepairPal data, the Subaru Forester has a reliability rating of 3.5 out of 5.0, ranking it 21st out of 26 for compact SUVs. While this ranking seems average, the context is important. The average annual repair cost is approximately $632, which is slightly higher than the class average of $521.

This cost difference is primarily due to the specific maintenance requirements of the Boxer engine and the All-Wheel Drive (AWD) system. Subarus require strict adherence to maintenance schedules. They are not “neglect-tolerant” vehicles like a Toyota Corolla, but they are exceptionally durable when properly serviced.

Engine and Transmission Durability

The core of the 2024 Forester is the 2.5-liter flat-four “Boxer” engine (FB25) paired with a Lineartronic CVT (Continuously Variable Transmission).

The Boxer Engine (FB25) The 2.5-liter engine is a naturally aspirated unit. Because it lacks a turbocharger (except on discontinued XT models or the Outback XT), there are fewer high-stress components to fail. The “flat” design sits lower in the chassis, reducing vibration.

  • Oil Consumption: Earlier Subaru engines (2011-2015) were notorious for burning oil. The modern FB25 engine in the 2024 model has tighter piston ring tolerances. While it is still wise to check your oil level every 2,000 miles, the excessive consumption issue is largely resolved.
  • Head Gaskets: This is the most famous Subaru stereotype. However, Subaru switched from single-layer to multi-layer steel head gaskets years ago. Head gasket failure is no longer a premature issue on these modern engines.

The Lineartronic CVT Early CVTs from the early 2010s had rubber-banding issues and durability concerns. The 2024 Forester uses a third-generation Lineartronic CVT. It uses a chain rather than a belt, which significantly increases durability and torque handling.

  • Wilderness Trim: If you opt for the Forester Wilderness, the transmission comes with an upgraded variator and oil cooler. This makes it the most durable choice if you plan on towing or driving in hot, mountainous regions.

Potential Trouble Spots to Watch

Even with high ratings, no vehicle is perfect. Based on owner forums and service bulletins for the fifth generation, here are the specific areas to monitor on a 2024 Forester.

1. Windshield Durability The acoustic glass used in modern Subarus is effective at reducing noise, but owners frequently report that it is prone to chipping and cracking from minor road debris. This has been a persistent complaint throughout the generation. Investing in $0 deductible glass coverage on your insurance policy is a smart financial move for Forester owners.

2. Battery Drain Subaru has struggled with parasitic battery drain in recent years, often linked to the DCM (Data Communication Module) searching for networks. While software updates have mitigated this, the stock batteries provided by Subaru are often criticized for having low Cold Cranking Amps (CCA). Replacing the OEM battery with a high-quality AGM aftermarket battery (like an Odyssey or Interstate) is a common “first upgrade” for long-term reliability.

3. Infotainment Glitches The 2024 model retains the physical buttons and knobs for climate control (unlike the touchscreen-only setup in the Outback and Crosstrek). This is a reliability advantage. Physical buttons do not crash. However, the Starlink screen can occasionally freeze or fail to pair with Apple CarPlay/Android Auto. These are usually nuisance issues resolved by a restart rather than catastrophic hardware failures.

Maintenance: The Key to 200,000 Miles

To ensure the 2024 Forester lasts beyond the warranty period, follow this specific advice that goes beyond the basic manual.

  • CVT Fluid: Subaru of America often labels the transmission fluid as “lifetime.” Do not believe this. If you want the transmission to last 200,000 miles, drain and fill the CVT fluid every 60,000 miles. This is critical for the long-term health of the valve body.
  • Differential Fluid: The Symmetrical AWD system is always on. Change the front and rear differential fluid every 30,000 to 60,000 miles to keep the gears protecting the drivetrain.
  • Cooling System: The Thermo Control Valve is a sensitive component. ensure you use only the specific Subaru Super Coolant to prevent corrosion or sensor errors.

Frequently Asked Questions

Is the 2024 Forester reliable enough for 10+ years of ownership? Yes. The 2024 model is the most refined version of the current generation. With adherence to the maintenance schedule (specifically oil and CVT fluid changes), reaching 10 years or 200,000 miles is a realistic expectation.

Should I buy the 2024 or wait for the redesigned 2025 Forester? If reliability is your top priority, the 2024 is the safer bet. The 2025 model introduces a new chassis structure and updated electronics. First-year models statistically have more manufacturing defects and recalls than the final year of a production run.

Does the 2024 Forester have turbo problems? No, because the 2024 Forester does not use a turbocharger. It uses a naturally aspirated 2.5-liter engine. This simplifies the mechanical layout and reduces the number of parts that can fail over time compared to turbocharged competitors.

Is the Forester expensive to repair? It is moderately priced. Parts are generally cheaper than European brands (VW or Mini) but slightly more expensive than high-volume domestic parts (Ford or Chevy). The complexity of the Boxer engine labor can sometimes drive up costs for tasks like spark plug replacement, as the engine creates tight clearances in the engine bay.
