Review CHEVROLET TRUCK Power Liftgate Struts Lid Motor Pull Down fits TAHOE 2017

The **2017 Chevrolet Tahoe Power Liftgate Struts (Part #640.GM8D17)** is a precision-engineered hydraulic component designed to enhance the seamless operation of the Tahoe s power liftgate, ensuring smooth, effortless opening and closing with minimal effort. These high-performance struts are engineered by General Motors to meet the rigorous demands of daily use, delivering reliable performance even under varying weather conditions, from scorching summer heat to freezing winter temperatures. Crafted from durable, corrosion-resistant materials, the struts feature a robust hydraulic cylinder and a robust motor assembly that works in tandem with the vehicle s liftgate mechanism to provide consistent, responsive movement. The motorized design eliminates the need for manual assistance, making it ideal for drivers who prioritize convenience and accessibility, particularly those with mobility considerations or those frequently transporting bulky items like strollers, luggage, or outdoor gear. The struts are compatible with the Tahoe s integrated power liftgate system, ensuring a perfect fit and seamless integration with the existing hardware, including the gate s hinges, latch, and electrical components. Whether navigating tight parking spaces, maneuvering through crowded driveways, or simply opening the gate with one hand, these struts provide the quiet, smooth operation that defines modern luxury SUV functionality. Built to withstand the test of time, they are designed for long-term durability, reducing the likelihood of premature wear or failure, and minimizing the need for frequent replacements. For owners seeking to restore or upgrade their Tahoe s liftgate system, these struts represent a direct, factory-recommended solution that combines performance, reliability, and ease of installation.

### **Pros and Cons of Buying a 2017 Chevrolet Tahoe with Power Liftgate Struts/Lid Motor Issues**

#### **Pros**

1. **Reliability and Durability** The 2017 Chevrolet Tahoe is built on a solid foundation with a proven V8 engine (6.2L V8 in most trims) that offers strong towing capacity (up to 9,600 lbs) and a comfortable ride. The frame and suspension are generally robust, making it a dependable SUV for daily driving and hauling.

2. **Power Liftgate Convenience** The power liftgate is a useful feature, especially for those who frequently carry groceries, luggage, or equipment. It eliminates the need to manually open the rear door, which can be helpful in tight parking spaces or when carrying heavy loads.

3. **Spacious Interior** The Tahoe offers ample cargo space (up to 108.3 cu. ft. behind the third row) and a comfortable seating arrangement for up to eight passengers. The third-row seats, while not as luxurious as in some luxury SUVs, provide adequate space for shorter passengers.

4. **Good Resale Value** Chevrolet Tahoes hold their value reasonably well compared to some competitors, meaning you may recover a decent portion of your investment if you sell or trade it in later.

5. **Available Tech and Safety Features** Many 2017 Tahoes come equipped with modern amenities such as Apple CarPlay/Android Auto, a 7-inch touchscreen, and safety features like forward collision alert, lane departure warning, and automatic emergency braking. Higher trims (e.g., LTZ, High Country) include even more advanced tech and luxury touches.

6. **Strong Towing and Hauling Capabilities** The V8 engine provides substantial power for towing trailers, boats, or ATVs, making it a practical choice for outdoor enthusiasts or those who need extra utility.

7. **Aftermarket Support** As a popular vehicle, parts and maintenance services are widely available, and there is a strong aftermarket community for modifications and repairs.

#### **Cons**

1. **Power Liftgate Struts/Lid Motor Failure** The most significant drawback of this particular vehicle is the reported failure of the power liftgate struts or lid motor. The liftgate may become difficult to open manually, or the motor may fail entirely, requiring costly repairs (often $500 $1,500 or more, depending on whether parts or labor are included). This issue has been documented in multiple 2017 2019 Tahoe models and is a known GM recall concern (NHTSA recall #17V-075). If the motor or struts are already failing, this could become a recurring expense.

2. **High Maintenance Costs** The V8 engine, while powerful, is thirsty for oil and fuel and may require more frequent oil changes than a smaller engine. Additionally, GM s reputation for higher repair costs (especially for non-luxury brands) means that parts and labor can add up over time.

3. **Fuel Efficiency** The V8 engine is not fuel-efficient, with EPA-estimated MPG ratings around 16 city / 22 highway. This can lead to higher operating costs, especially for long-distance driving.

4. **Comfort and Noise** Some owners report that the Tahoe can be noisy at highway speeds, particularly with the V8 engine. The ride quality is firm, which may not be ideal for those seeking a plush, luxury SUV experience.

5. **Third-Row Comfort Limitations** The third row is tight for adults, and the legroom is limited. Frequent third-row passengers may find the seating uncomfortable for long trips.

6. **Transmission Issues (Automatic Models)** Some 2017 Tahoes with the 6T70 transmission have reported rough shifting or delayed engagement, particularly in cold weather. While not universal, this can be frustrating for daily drivers.

7. **Depreciation** Like many SUVs, the Tahoe loses value quickly. If you plan to keep it long-term, the depreciation may offset some of the initial cost savings compared to newer models.

### **Ending Conclusion**

The 2017 Chevrolet Tahoe with power liftgate issues is a capable and practical SUV for those who prioritize towing, space, and durability. However, the power liftgate motor or strut failure is a significant drawback that could lead to unexpected repair costs. If you find a well-maintained example with a verified working liftgate or are prepared to budget for potential repairs, it can be a solid buy. Alternatively, if the liftgate is already malfunctioning or you re uncomfortable with the risk of future failure, it may be worth considering a different year or model (e.g., a 2016 or 2018 Tahoe, depending on the specific issues) or exploring alternatives like the Ford Expedition, Toyota Sequoia, or a used luxury SUV with fewer known defects.

---

### **Recommendation**

1. **Inspect the Liftgate Thoroughly** Before purchasing, test the liftgate motor and struts manually and electronically. If they are already failing or show signs of wear, factor in the cost of repair (or replacement) upfront. Consider getting a pre-purchase inspection from a trusted mechanic to assess the condition.

2. **Check for Recalls and Service History** Ensure the vehicle has all pending recalls addressed (especially the liftgate motor recall) and that it has a complete service history. A vehicle with a clean maintenance record is less likely to have hidden issues.

3. **Budget for Potential Repairs** If the liftgate is functional but aging, set aside funds for future repairs. If it s already broken, decide whether the cost of fixing it is justified by the vehicle s overall condition and value.

4. **Consider Alternatives** If the liftgate issue is a dealbreaker, look for a Tahoe from a different year (e.g., 2016 or 2018) that may not have the same problem. Alternatively, explore other full-size SUVs with fewer known defects or better reliability ratings.

5. **Negotiate the Price** If the liftgate is failing or has a known issue, use this as leverage to negotiate a lower purchase price. Sellers may be more willing to accept a lower offer if they know the vehicle has a known defect.

6. **Prioritize Other Features** If you don t rely heavily on the liftgate, focus on other aspects of the vehicle, such as engine condition, transmission smoothness, and interior wear. A well-maintained Tahoe with a working liftgate can still be a great value.

**Final Verdict:** The 2017 Chevrolet Tahoe is a strong SUV for those who need towing power and space, but the power liftgate issue is a critical factor. If you re prepared to address the liftgate problem and the rest of the vehicle is in good condition, it can be a worthwhile purchase. Otherwise, consider alternatives or a different year model to avoid potential repair costs.
