Review CHEVROLET Glass Lower Garnish fits SILVERADO 1500 2015–2018

The **Chevrolet 2015-2018 Silverado 1500 Glass Lower Garnish (Part #23455514)** is a precision-engineered trim component designed to elevate both the aesthetic appeal and functional integrity of the iconic full-size pickup truck. Crafted from high-quality, tempered glass with a sleek, matte black finish, this garnish panel seamlessly integrates into the lower body of the Silverado, bridging the gap between the wheel wells and the rocker panels while providing a refined, modern look. Its streamlined design not only enhances the truck s aggressive yet sophisticated stance but also helps protect the lower body from minor road debris, scratches, and stone chips, thereby preserving the vehicle s resale value and long-term appearance. The garnish features a clean, integrated mounting system that ensures a snug, vibration-dampening fit, reducing rattles and maintaining a polished look even during high-speed driving or over rough terrain. Ideal for owners seeking to restore or upgrade their Silverado s lower body panels, this garnish is a direct replacement for the original equipment, ensuring compatibility with the 2015 through 2018 model years across various trim levels, including the LT, LTZ, Custom, and High Country editions. Whether used as part of a full restoration project or as a standalone cosmetic enhancement, this glass garnish delivers a blend of durability, style, and practicality, making it a standout choice for Chevrolet enthusiasts who demand both form and function in their vehicles.

### **Pros and Cons of Buying a 2015 2018 Chevrolet Silverado 1500 (VIN 23455514) with a Glass Lower Garnish Issue**

#### **Pros**

1. **Reliability and Durability** The Chevrolet Silverado 1500 is known for its strong frame, robust engine options (especially the 5.3L V8 and 6.2L V8), and heavy-duty towing capacity, making it a solid choice for work or off-road use.

2. **Proven Engine Options** The 5.3L V8 (with EcoTec3) and 6.2L V8 (with Active Fuel Management) are reliable powerplants if well-maintained. The 3.0L Duramax diesel (if equipped) offers strong torque for towing and hauling.

3. **High Towing and Hauling Capacity** Even in these model years, the Silverado 1500 can tow up to **9,300 12,000 lbs** (depending on configuration), making it suitable for trailers, boats, and heavy loads.

4. **Available Off-Road Features** Some trims (especially the Custom, Custom Plus, and High Country) come with off-road packages, including skid plates, all-terrain tires, and a locking rear differential, which can be useful for rugged use.

5. **Resale Value** The Silverado 1500 holds its value relatively well compared to some competitors, especially in the full-size truck market.

6. **Comfortable Interior** The cabin is spacious with decent sound insulation, making long drives more comfortable. The 2016 2018 models saw slight improvements in interior materials and tech features.

- **MyLink infotainment** (with Bluetooth, USB, and optional navigation)

- **Forward Collision Alert, Blind Spot Monitoring, and Trailer Backup Assist** (on higher trims)

- **Available 8-inch touchscreen** (2016 models)

8. **Parts and Service Availability** As a Chevrolet, parts are widely available, and mechanics familiar with GM trucks can service it without major issues.

9. **Potential for Modifications** The Silverado s platform allows for aftermarket upgrades, including lift kits, exhaust systems, and performance parts.

10. **Lower Purchase Price** Since these are mid-cycle models (2015 2018), they are generally cheaper than newer trucks, offering better value for the money.

#### **Cons**

1. **Glass Lower Garnish Issue (VIN 23455514)**

- The **glass lower garnish** (a decorative panel below the door) is known to **crack or shatter** due to poor-quality glass or stress from door opening/closing.

- This is a **common complaint** in these years, and GM issued a **recall (NHTSA Recall #17V-028)** for affected vehicles (2015 2018 Silverado 1500 with certain VINs).

- **Repair cost:** GM offered a **free replacement**, but if not done, the glass may need to be replaced at a dealership ( $100 $200 per side).

- **Risk:** If the glass breaks, it could cause **sharp edges, door misalignment, or even door lock failure**.

2. **Transmission Issues (Especially 6T70/6T75 Automatic)**

- Some owners report **rough shifting, delayed engagement, or transmission failure** in the 6-speed automatic transmissions (common in these years).

- **Symptoms:** Jerking, grinding, or the transmission getting stuck in a gear.

- **Solution:** Regular fluid changes and monitoring for warning signs can help, but a rebuild may be needed later ( $2,000 $3,500).

3. **Electrical Gremlins**

- The **MyLink system** can be finicky, with **software glitches, touchscreen freezes, or sensor failures**.

- **Power window or door lock malfunctions** are also reported.

- **Solution:** Software updates (from a dealer) or simple resets may fix minor issues.

4. **Rust Concerns (Especially in Snowy/Corrosive Areas)**

- If the truck was driven in **salted roads or humid climates**, check for **underbody rust, wheel wells, and frame corrosion**.

- **Pre-purchase inspection (PPI) recommended** to avoid hidden rust damage.

5. **Fuel Economy Not Great**

- The **V8 engines (5.3L, 6.2L) average 15 18 MPG city / 20 23 MPG highway**, which is **lower than competitors** like the Ford F-150 or Ram 1500.

- The **3.0L Duramax diesel** improves this ( 18 22 MPG), but it s more expensive to maintain.

6. **Interior Quality Varies by Trim**

- Lower trims (LT, LTZ) have **cheaper plastics and less sound insulation**.

- Higher trims (Custom, High Country) feel more premium but still not as refined as some rivals.

7. **Resale Depreciation**

- While it holds value better than some trucks, **newer models (2020 ) depreciate slower**, meaning this truck may lose value faster over time.

8. **Potential Oil Leaks**

- Some owners report **oil leaks from valve covers, oil filter housing, or rear main seal**, especially in higher-mileage examples.

- **Check for oil spots under the truck** during inspection.

9. **Limited Off-Road Capabilities (Standard Trims)**

- Without an **off-road package**, the Silverado is **not as capable** as competitors like the Ford F-150 Raptor or Ram 1500 TRX.

10. **Recall History**

- **Airbag deployment issues**

- **Fuel pump failures**

- **Transmission control module problems**

- **Always check NHTSA s recall database** before buying.

### **Conclusion**

The **2015 2018 Chevrolet Silverado 1500 (VIN 23455514)** is a **solid workhorse truck** with **strong towing, reliable engines, and a durable frame** but it comes with **notable drawbacks**, particularly the **glass lower garnish issue** and **potential transmission/electrical problems**.

**If the glass garnish has already been replaced (via recall or dealer service), the truck could be a great buy** especially if it has **low miles, good maintenance records, and no major rust or transmission issues**.

**If the glass garnish is still broken or the seller hasn t addressed it**, this could be a **major red flag**, as it may indicate **neglect or a higher risk of future door problems**.

### **Recommendation**

- **Transmission fluid condition** (color, smell, leaks)

- **Oil leaks** (valve covers, rear main seal)

- **Glass garnish integrity** (is it cracked? Has it been replaced?)

- **Rust in wheel wells, frame, and undercarriage**

- **Electrical systems (windows, locks, infotainment)**

2. **Verify Recall Fixes**

- Confirm that the **glass garnish recall (NHTSA #17V-028)** has been addressed.

- Check for **other outstanding recalls** on the VIN.

3. **Check Maintenance Records**

- **Transmission fluid changes** (every 60K 100K miles)

- **Timing belt/chain service** (if applicable)

- **Suspension and brake inspections**

4. **Negotiate Based on Issues Found**

- If the **glass garnish is broken**, demand a **free replacement** or **price reduction**.

- If the **transmission shows wear**, consider **factoring in repair costs** in the purchase price.

5. **Consider Alternatives if Possible**

- If the **glass garnish issue is a dealbreaker**, look for a **2019 Silverado** (which improved on some of these problems) or a **Ford F-150 (2015 with PowerShift transmission)** or **Ram 1500 (2019 with EcoDiesel)** for better long-term reliability.

### **Final Verdict: Should You Buy It?**

- The **glass garnish has been properly repaired**.

- The **transmission and electrical systems are in good condition**.

- The **truck has low miles (

- You **negotiate a fair price** based on any minor issues.

- The **glass garnish
