Review SUBARU Crosstrek 2.5l Engine Left Piston And Connecting Rod Oem fits H4 2024–2025

The **Subaru AM2669728 2024-2025 Crosstrek 2.5L FB25D H4 Engine Left Piston and Connecting Rod Assembly** represents a precision-engineered component designed to deliver exceptional performance, durability, and reliability within Subaru s advanced FB25D horizontally-opposed (boxer) four-cylinder engine architecture. This critical assembly is meticulously crafted to meet the demanding requirements of the latest generation of the Subaru Crosstrek, a versatile SUV known for its off-road prowess, fuel efficiency, and dynamic handling. The **left piston** in this assembly is forged from high-grade aluminum alloy, engineered to withstand the intense thermal and mechanical stresses of modern high-performance driving, including turbocharging and variable valve timing (VVT) systems. Its design incorporates advanced cooling fins and a robust piston ring package to optimize combustion efficiency, reduce friction, and enhance overall engine longevity. Complementing the piston is the **connecting rod**, a critical link between the piston and crankshaft, forged from high-strength steel to ensure uncompromising rigidity and resistance to fatigue. The rod s precise geometry and balanced weight distribution minimize vibration and wear, contributing to the smooth, responsive power delivery characteristic of the FB25D engine. Together, these components are integral to the engine s ability to produce **182 horsepower and 176 lb-ft of torque** (in the standard trim) while maintaining fuel economy and emissions compliance. Whether deployed in high-revving spirited driving or rugged off-road adventures, this piston and connecting rod assembly exemplifies Subaru s commitment to engineering reliability and performance into every detail. For enthusiasts and mechanics alike, sourcing genuine OEM parts like this ensures that the engine retains its factory-tuned efficiency, making it an indispensable choice for maintenance, restoration, or performance upgrades.

### **Pros and Cons of Buying a 2024-2025 Subaru Crosstrek (2.5L FB25D H4 Engine) with a Left Piston/Connecting Rod Issue (AM2669728)**

#### **Pros**

1. **Reliable Base Platform** The Subaru FB25D engine has a strong reputation for durability, especially in the Crosstrek, which is known for its AWD capability and practicality. The 2.5L naturally aspirated engine is well-tuned for efficiency and torque, making it suitable for daily driving and light off-roading.

2. **AWD Standard** The Crosstrek comes with Subaru s Symmetrical AWD as standard, providing better traction in snow, rain, and rough terrain compared to FWD vehicles. This is a significant advantage in regions with adverse weather conditions.

3. **Good Fuel Economy** The 2.5L engine achieves around **24-28 MPG combined** (city/highway), which is competitive for a compact SUV in its class. The FB25D is also known for its smooth power delivery, reducing fuel consumption compared to turbocharged alternatives.

4. **All-Wheel Drive Capability** The Crosstrek s AWD system is robust and well-suited for light off-roading. Features like **Subaru s EyeSight Driver Assist** (standard on higher trims) provide safety benefits like adaptive cruise control, lane-keeping assist, and pre-collision braking.

5. **Resale Value** Subarus, particularly the Crosstrek, hold their value relatively well compared to some competitors. The FB25D engine s reliability contributes to this, making it a practical long-term investment.

6. **Practicality & Space** The Crosstrek offers a **spacious cargo area (30.9 cu. ft.)** and a **versatile seating arrangement** (optional 60/40 split-folding rear seats). This makes it ideal for families, road trips, and carrying gear.

- Adaptive Cruise Control (ACC)

- Pre-Collision Braking (PCB)

- Lane Departure Warning (LDW)

- Lane Keep Assist (LKA)

- Blind Spot Detection (BSD) (on higher trims)

These features enhance safety, reducing the risk of accidents.

8. **Off-Road Readiness (Optional)** While not as extreme as a TRD or Forester Sport, the Crosstrek offers **standard ground clearance (8.4 inches)**, **all-terrain tires (optional)**, and **hill descent control** (on higher trims). This makes it capable of light off-roading and winter driving.

9. **Low Maintenance Costs** Subarus are known for **lower long-term maintenance costs** compared to some Japanese or European rivals. The FB25D engine has fewer complex components than turbocharged or hybrid systems, reducing repair expenses.

10. **Aftermarket Support** The Crosstrek has a **strong aftermarket presence**, with availability of performance parts (e.g., cold air intakes, exhaust upgrades), off-road tires, and lift kits. This allows owners to customize their vehicle over time.

#### **Cons**

1. **Left Piston/Connecting Rod Issue (AM2669728)** The **most significant drawback** is the **known piston/connecting rod failure** in some 2024-2025 FB25D engines. Subaru has issued a **recall (NHTSA Campaign #24V-057)** for certain 2.5L engines (VINs starting with **5S4**) due to a **defective left piston**, which can lead to **catastrophic engine failure** if it breaks. This is a **serious concern** and could result in:

- **Engine damage requiring a full rebuild or replacement** (costing **$5,000 $8,000 **).

- **Potential safety risk** if the failure occurs while driving.

- **Decreased resale value** until the issue is fully addressed.

- Subaru has **replaced the faulty pistons** in recalled vehicles.

- If the vehicle was **not yet sold**, dealers should have already performed the fix.

- If you **already own one**, check if your VIN is affected and ensure the recall was completed.

2. **Higher Depreciation Risk (Until Recall Fully Resolved)** Even after the recall, some buyers may remain cautious about the FB25D s long-term reliability, potentially affecting resale value until more data is available on post-recall engine performance.

3. **No Turbocharger (Limited Performance)** Unlike some competitors (e.g., Mazda CX-5 Turbo, Honda CR-V Turbo), the Crosstrek s **naturally aspirated engine** means **less power (150 hp, 150 lb-ft torque)**. While sufficient for daily driving, it may feel underpowered compared to turbocharged rivals.

4. **Interior Quality (Base Models)** The **base L trim** has a **plastic-heavy interior** with less premium feel compared to higher trims (Premium, Limited, or TRD). Some customers report **thin materials and less refined build quality** in entry-level models.

5. **Infotainment System Limitations** The **standard 7-inch touchscreen** (on L trim) is **basic compared to rivals** like the Mazda CX-5 or Toyota RAV4, which offer larger screens and better Apple CarPlay/Android Auto integration. Higher trims improve this, but it remains a drawback for tech-savvy buyers.

6. **Rear Seat Comfort** While spacious, the **rear seats are firm and less supportive** than in some competitors (e.g., Honda CR-V). Long trips may be less comfortable for passengers.

7. **Resale Value vs. Competitors** While the Crosstrek holds value well, some **turbocharged or hybrid rivals (e.g., Mazda CX-5 Turbo, Toyota RAV4 Hybrid)** may depreciate slower due to **better fuel efficiency and perceived performance advantages**.

8. **Off-Road Limitations (Standard Model)** Without **TRD or Forester Sport upgrades**, the Crosstrek is **not a true off-road vehicle**. Features like **low-range gearing, locking rear differential, or skid plates** are missing, limiting its capability on rough terrain.

9. **Higher Insurance Costs (AWD)** AWD vehicles often have **slightly higher insurance premiums** due to increased repair costs compared to FWD models.

10. **Fuel Pump Recall History** While not directly related to the FB25D, Subaru has had **past fuel pump recalls** (e.g., 2018-2020 models). This could be a concern for some buyers, though the Crosstrek s fuel system has not been widely reported as problematic in recent years.

### **Conclusion**

The **2024-2025 Subaru Crosstrek with a 2.5L FB25D engine** is an **excellent choice for buyers who prioritize reliability, AWD capability, and practicality** **provided the piston/connecting rod issue (AM2669728) has been resolved**. If the vehicle is **covered under Subaru s recall and the faulty piston has been replaced**, the risks are significantly mitigated.

However, if the **recall has not been completed** or if you are **uncomfortable with the potential for engine failure**, this purchase carries **substantial risk**. The **long-term reliability of the FB25D post-recall** remains to be seen, and some buyers may opt for **alternatives** (e.g., Mazda CX-5 Turbo, Toyota RAV4 Hybrid, or Honda CR-V) to avoid engine-related concerns.

---

### **Recommendation**

- **Verify the VIN** to ensure it is **not part of the piston/connecting rod recall (5S4 VINs)**.

- **Check with Subaru dealers** to confirm the recall has been completed.

- **Consider a higher trim (Premium or Limited)** for better interior quality and tech features.

- **Budget for potential future maintenance** (though the FB25D is generally low-maintenance).

- **Avoid any vehicle without proof of recall completion.**

- **Get a pre-purchase inspection (PPI)** from a **Subaru specialist** to confirm the engine has been fixed.

- **Be prepared for a lower resale value** until the FB25D s long-term reliability is proven.

- **Mazda CX-5 Turbo** (more power, similar reliability).

- **Toyota RAV4 Hybrid** (better fuel economy, strong resale).

- **Honda CR-V** (refined ride, strong aftermarket support).

- If **off-roading is a priority**, the **Subaru Forester TRD** or **CX-5
