### **Pros and Cons of Buying a 2017-2019 Ford Explorer with a HB5Z3504V Electric Assist Motor (Rack & Pinion System)**

#### **Pros**

1. **Electric Power-Assist Steering (EPAS) Benefits**

- The HB5Z3504V motor provides smooth, variable electric assist, reducing steering effort especially useful in heavy traffic, tight parking spots, or when towing.

- Enhances maneuverability compared to traditional hydraulic systems, which can feel sluggish or require more effort.

- Reduces driver fatigue on long drives, particularly in urban or stop-and-go conditions.

2. **Improved Fuel Efficiency**

- Electric assist steering eliminates the need for a hydraulic pump, which is powered by the engine. This small but consistent power draw can slightly improve fuel economy, though the impact is modest compared to other efficiency upgrades.

- The system is more efficient than older hydraulic steering setups, as it only draws power when needed.

3. **Reliability and Durability**

- Ford s rack-and-pinion steering is generally robust, with fewer moving parts than hydraulic systems, reducing wear over time.

- Electric motors have fewer fluid leaks or belt replacements compared to hydraulic steering, which can be a maintenance headache.

- The HB5Z3504V motor is a standard component in Ford s lineup, meaning parts and labor are widely available.

4. **Modern Feel and Technology**

- The electric assist provides a more responsive and precise steering feel, which can make the Explorer feel more modern and engaging to drive.

- Some drivers appreciate the lack of hydraulic whine or pump noise, contributing to a quieter cabin.

5. **Potential Resale Value**

- Vehicles with electric power steering are often seen as more advanced, which could slightly boost resale value compared to older hydraulic systems.

- If maintained well, the steering system is unlikely to be a major selling point against competitors.

6. **Low Maintenance**

- No need for regular fluid changes, belt inspections, or pump replacements, which are common with hydraulic systems.

- The motor itself has minimal wear points, though electrical connections should still be checked periodically.

---

#### **Cons**

1. **Higher Initial Cost**

- Electric power steering systems are generally more expensive to install than hydraulic ones, though this is already accounted for in the vehicle s price.

- If the motor fails (though rare), repairs can be costly, especially if labor rates are high.

2. **Potential for Electrical Issues**

- Like any electrical component, the motor or wiring could fail due to corrosion, wear, or electrical faults. This is less common but more difficult to diagnose than hydraulic leaks.

- If the motor or control module fails, it may require professional diagnostics, which can be time-consuming and expensive.

3. **Less Feedback for Off-Road or Heavy Towing**

- While electric assist makes steering easier, some drivers prefer the heavier feedback of hydraulic systems for off-road driving or towing heavy loads. The assist can feel too light in extreme conditions.

- In extreme off-road scenarios, the lack of hydraulic resistance might make it harder to sense terrain or obstacles.

4. **Dependence on Battery and Electrical System**

- The motor draws power from the vehicle s electrical system. In rare cases, a failing alternator or battery could affect steering assist, though this is unlikely to render it completely inoperable.

- If the vehicle s electrical system is compromised (e.g., due to a dead battery or wiring issues), the assist may not function properly.

5. **Limited Aftermarket Support**

- While Ford s EPAS is reliable, aftermarket modifications (e.g., heavy-duty steering upgrades) are less common than for hydraulic systems. Custom tuning or heavy-duty parts may be harder to find.

- Some performance enthusiasts prefer hydraulic steering for its adjustability and robustness in high-performance applications.

6. **Potential for Software Glitches**

- Electric steering systems are controlled by software, which could occasionally experience glitches (e.g., sudden changes in assist level or intermittent failure). While rare, this is a possibility with any electronic system.

- Updates or recalibrations may be needed if the vehicle undergoes major modifications (e.g., suspension changes).

7. **Noisier Operation in Some Cases**

- Some drivers report that electric steering motors can produce a slight hum or whine under certain conditions, though this is usually minimal compared to hydraulic pumps.

### **Conclusion**

The **2017-2019 Ford Explorer with the HB5Z3504V electric assist motor** offers a **reliable, low-maintenance, and fuel-efficient** steering system that enhances comfort and ease of use in daily driving. The electric assist provides a **modern feel**, reduces driver fatigue, and eliminates the hassles of hydraulic fluid maintenance. For most drivers, especially those prioritizing convenience and efficiency, this system is a **strong advantage**.

However, **potential downsides** include **higher repair costs if the motor fails**, **less feedback for off-road or towing**, and **rare electrical issues**. If you plan to **tow heavily, drive off-road frequently, or modify the vehicle aggressively**, you might prefer a hydraulic system for its robustness. Otherwise, the **electric assist is a well-engineered, practical choice** that outweighs its minor drawbacks for the average driver.

---

### **Recommendation**

- You prioritize **comfort, fuel efficiency, and low maintenance** in your daily driving.

- You frequently drive in **urban areas or stop-and-go traffic**, where electric assist shines.

- You want a **modern feel** without the hassle of hydraulic steering fluid changes.

- You don t plan to **tow excessively or drive off-road heavily**, as the assist may feel too light in those scenarios.

- You **tow large trailers or drive frequently off-road**, where hydraulic steering s feedback is preferable.

- You re on a **tight budget** and want to avoid potential electrical repair costs.

- You plan **heavy modifications** that might conflict with the electric assist system.

**Final Verdict:** For the **average driver**, the **electric assist steering in this Explorer is a solid, practical choice** that offers **long-term reliability and convenience**. If you re comfortable with modern vehicle technology and don t need the heavy-duty feedback of hydraulic steering, this system is **worth the trade-offs**. Always **inspect the steering system thoroughly** (check for electrical connections, motor operation, and any warning lights) before purchasing to ensure it s in good working order.
