### **Pros and Cons of Buying a Used Infiniti QX56/QX80 Front Left Driver Seat Control Switch (Part # 870121JE6B, 2011-2017 Models)**

1. **Direct Compatibility** This part is designed specifically for the 2011-2017 Infiniti QX56 (U.S. market) and QX80 (global market), ensuring a proper fit without modifications.

2. **OEM Quality** As an original equipment manufacturer (OEM) part, it meets Infiniti s manufacturing standards, reducing the risk of premature failure compared to aftermarket knockoffs.

3. **Reliability** The seat control switch is a critical component for adjusting seat position, lumbar support, and reclining. A functional switch prevents inconvenience during use.

4. **Ease of Installation** Since it s a direct replacement, installation typically requires only basic tools and does not involve wiring or major modifications.

5. **Warranty Coverage** If purchased from a reputable dealer or online retailer, it may come with a limited warranty, providing peace of mind against defects.

6. **Prevents Further Damage** A failing switch can sometimes cause intermittent electrical issues or even damage to the seat motor over time. Replacing it early avoids more costly repairs.

1. **Cost** OEM parts are generally more expensive than aftermarket alternatives, which may be a consideration for budget-conscious buyers.

2. **Availability & Lead Time** Depending on the supplier, OEM parts may not always be in stock, leading to potential delays in receiving the replacement.

3. **Potential Counterfeit Risk** If purchasing from an unverified seller, there is a chance of receiving a counterfeit or low-quality part that fails quickly.

4. **Labor Costs** While the part itself is straightforward, if you re not comfortable with basic automotive repairs, you may need to pay a mechanic for installation.

5. **Age of the Vehicle** If the rest of the vehicle is aging, replacing just the switch may not address underlying issues (e.g., worn seat tracks, failing motors).

6. **Resale Value Impact** Some buyers may prefer a vehicle with all OEM components, so a known replacement part might slightly reduce resale appeal (though this is usually negligible).

### **Conclusion**

The **Infiniti QX56/QX80 front left driver seat control switch (870121JE6B)** is a **practical and reliable OEM replacement** for vehicles in the 2011-2017 model range. Its primary advantage is **direct compatibility and durability**, ensuring smooth operation of the seat controls. However, the **higher cost and potential availability issues** are the main drawbacks.

If the switch is failing (e.g., unresponsive buttons, intermittent operation, or complete failure), replacing it with this OEM part is a **wise investment** to restore functionality and prevent further electrical or mechanical issues. For those on a tight budget, a **high-quality aftermarket alternative** (from a trusted brand like Dorman or ACDelco) could be a cost-effective substitute, though OEM remains the safest choice for long-term reliability.

### **Recommendation**

- **Buy from a trusted source** (Infiniti dealership, reputable online marketplaces like RockAuto, or eBay with seller verification) to ensure authenticity.

- **Compare pricing** between OEM and aftermarket options if budget is a concern, but prioritize quality to avoid repeated replacements.

- **Inspect the switch thoroughly** before purchasing look for signs of wear, corrosion, or damage that could indicate a faulty unit.

- **Consider DIY installation** if comfortable with basic automotive work; otherwise, have a mechanic handle it to avoid voiding any warranty.

- **Check for bundled parts** some sellers offer seat motor replacements or wiring harnesses if the issue is more complex.

**Final Verdict:** This is a **solid OEM part worth purchasing** for restoring proper seat control functionality in your Infiniti QX56/QX80. The benefits of reliability and compatibility outweigh the minor drawbacks of cost and availability.
