### **Pros and Cons of Buying a 2024-2025 Subaru Crosstrek with a 2.5L FB25D Engine (Right-Hand Connecting Rod Piston Issue)**

#### **Pros**

1. **Reliability and Proven Engine Design**

The FB25D engine, based on Subaru s FB series, has a strong reputation for durability. It features a horizontally opposed (boxer) configuration, which provides excellent balance, smooth operation, and a low center of gravity benefits that enhance handling and comfort. Subaru s FB engines are known for longevity, especially when maintained properly.

2. **All-Wheel Drive Standard**

The Crosstrek comes standard with Subaru s Symmetrical All-Wheel Drive (AWD), making it highly capable in snow, rain, and off-road conditions. This is particularly valuable in regions with harsh winter weather or uneven terrain.

3. **Fuel Efficiency**

The 2.5L FB25D engine delivers solid fuel economy for a compact SUV. In the 2024-2025 Crosstrek, it achieves approximately **26-30 MPG combined** (city/highway), depending on the trim and transmission (CVT or manual). This is competitive for its class, especially when compared to some turbocharged rivals.

4. **Off-Road Capability**

The Crosstrek is Subaru s flagship compact SUV, designed with off-road performance in mind. Features like **traction control, hill descent control, and a ground clearance of 8.3 inches** make it suitable for light off-roading, trail use, and rugged conditions. The **EyeSight Driver Assist Technology** also aids in safety on both paved and unpaved roads.

5. **Standard Safety Features**

Subaru s EyeSight system includes **adaptive cruise control, lane-keeping assist, pre-collision braking, and blind-spot detection**, which enhances safety and reduces the risk of accidents. The Crosstrek also earns top safety ratings from the NHTSA and IIHS.

6. **Cargo Space and Practicality**

With **26.3 cubic feet of cargo space** (behind the rear seats) and **69.4 cubic feet with seats folded**, the Crosstrek offers generous storage for its class. The roof rails and available roof rack provide additional carrying capacity for outdoor gear or luggage.

7. **Resale Value**

Subaru vehicles, particularly the Crosstrek, hold their value well due to their reputation for reliability and practicality. This means you ll likely recoup a significant portion of your investment when it s time to sell or trade in.

8. **Available Tech and Comfort Features**

- **Heated and ventilated seats**

- **Wireless Apple CarPlay and Android Auto**

- **Digital gauge cluster**

- **Ambient lighting**

- **Available leather upholstery and premium audio**

These features enhance comfort and connectivity, making daily driving more enjoyable.

9. **Low Maintenance Costs**

Subaru s FB engines and AWD systems are relatively inexpensive to maintain compared to some competitors. Regular oil changes, timing belt replacements (every 105,000 miles), and basic upkeep keep the vehicle running smoothly without excessive costs.

10. **Environmental Considerations**

The FB25D engine is not turbocharged, which means it avoids some of the common issues associated with forced induction (e.g., carbon buildup, turbo failure). It also tends to be more reliable in extreme climates where turbocharged engines may struggle.

#### **Cons**

1. **Right-Hand Connecting Rod Piston Issue (AM2669723)**

The **AM2669723** code specifically refers to a **right-hand connecting rod piston problem** in the FB25D engine. This is a known **engine failure mode** where the piston in the right-hand cylinder can fracture or seize, leading to catastrophic engine damage. Subaru has issued **recalls and service bulletins** addressing this issue, particularly in models produced between **2018 and 2023**. While the 2024-2025 Crosstrek may not yet be widely affected, it is part of the same engine family, and this issue could emerge over time.

- **Risk:** If this issue occurs, it can result in **complete engine failure**, requiring a **full engine replacement** (a costly repair, often exceeding $5,000).

- **Prevention:** Subaru has **replaced the right-hand piston** in affected engines under warranty. If you re buying a used or early-production 2024-2025 model, verify that the dealer has performed this fix. Newer models (post-2023) may have been updated to mitigate this risk, but it s not guaranteed.

2. **CVT Transmission Reliability Concerns**

The Crosstrek s standard **continuously variable transmission (CVT)** has received mixed reviews regarding longevity. Some owners report **premature wear, jerking, or failure**, particularly in high-mileage vehicles. While Subaru has improved CVT reliability in recent years, it remains a potential weak point compared to traditional automatic transmissions.

- **Mitigation:** Stick to models with **low mileage** and ensure the CVT fluid has been recently changed (CVT fluid degrades over time and must be replaced every **60,000 100,000 miles**).

3. **Interior Quality and Build**

The Crosstrek s interior is functional but **not as premium** as some competitors (e.g., Honda CR-V or Mazda CX-5). Plastic trim can feel **cheap in some areas**, and the **seat comfort** is adequate but not exceptional for long drives. Higher trims improve this, but budget models may feel more utilitarian than luxurious.

4. **Resale Depreciation**

While Subaru Crosstreks hold value well, they do not appreciate as quickly as some luxury or high-demand SUVs. If you plan to sell or upgrade in a few years, the depreciation rate may be higher than you d like.

5. **Limited Performance**

The **naturally aspirated 2.5L engine** does not provide the same power or acceleration as turbocharged rivals (e.g., Ford EcoBoost, Toyota 2.5T). The Crosstrek accelerates **0-60 mph in about 8.5 9.5 seconds**, which is slower than turbocharged competitors (e.g., 6.5 7.5 seconds). If you prioritize performance, you may find other options more engaging.

6. **Higher Insurance Costs**

Due to its AWD standard and off-road capabilities, the Crosstrek may have **higher insurance premiums** compared to front-wheel-drive competitors. This is particularly true in areas with frequent theft or high accident rates.

7. **Limited Aftermarket Support**

While Subaru has a loyal following, its aftermarket parts and tuning community are **not as extensive** as Toyota or Honda. This can make modifications or repairs slightly more difficult or expensive.

8. **Fuel Economy Trade-Offs**

While the Crosstrek is fuel-efficient, its **AWD system and heavier weight** (compared to FWD rivals) can slightly reduce MPG in real-world driving conditions. In stop-and-go traffic or hilly areas, efficiency may dip below the EPA-estimated figures.

9. **Potential for Rust in Snowy Climates**

Subaru s boxer engines and AWD systems are prone to **rust in salt-treated roads**. If you live in a region with heavy winter maintenance, **underbody corrosion** can be a concern over time. Regular undercarriage treatment can help mitigate this.

10. **Limited Luxury or Tech Upgrades**

Compared to rivals like the **Toyota RAV4 Prime (hybrid) or Mazda CX-5 Turbo**, the Crosstrek lacks **advanced hybrid technology or turbocharged performance**. If you want cutting-edge efficiency or sporty handling, other options may appeal more.

### **Conclusion**

The **2024-2025 Subaru Crosstrek with a 2.5L FB25D engine** is a **practical, capable, and reliable** compact SUV, especially for buyers who prioritize **AWD, off-road ability, and durability**. Its **proven engine design, strong safety features, and good fuel economy** make it an excellent choice for families, adventurers, and everyday drivers. However, the **right-hand connecting rod piston issue (AM2669723)** is a **critical flaw** that could lead to **catastrophic engine failure** if not addressed. This is not unique to 2024-2025 models but extends from earlier years, so **verifying the fix is in place** is essential.

If you **buy new or certified pre-owned**, ensure the dealer has performed the **piston replacement** under Subaru s recall. If buying used, **check maintenance records** for any signs of engine stress or unusual noises. The **CVT transmission** is another area to monitor, as premature failure could be costly.

For buyers who **value reliability, off-road capability, and practicality over high performance or luxury**, the Crosstrek is a **strong choice**. However, if you **prioritize fuel efficiency, lower maintenance costs, or
