### **Pros and Cons of Buying a 2014 2019 GMC Sierra 1500 Crew Cab (GM 23456647) with Manual Power Steering Column**
#### **Pros**
1. **Reliability and Durability**
The 2014 2019 GMC Sierra 1500, particularly with the Duramax diesel (common in this generation), is known for its robust build quality and longevity. The 6.6L Duramax V8 (L5P engine) is a well-regarded diesel engine that can easily exceed 300,000 miles with proper maintenance. Gas models (5.3L V8 or 3.7L V6) are also durable, though less fuel-efficient than diesel.
2. **Strong Resale Value**
Full-size trucks from this era retain their value well, especially diesel models. The Crew Cab configuration is popular, so finding a used buyer later should not be difficult.
3. **Spacious and Versatile Interior**
The Crew Cab offers ample seating for five (or six with bench seats) and a large cargo area. The high roof provides headroom, making it comfortable for taller passengers.
4. **Available Technology and Comfort Features**
Depending on the trim, these trucks come with features like:- **Uconnect infotainment system** (with Bluetooth, USB, and optional navigation)
- **Heated/cooled seats** (higher trims)
- **Adaptive cruise control** (on some models)
- **Available 4WD systems** (Dual4, 4x4, or 4x4 HD, depending on configuration)
- **Comfortable suspension options** (e.g., Bilstein shocks on higher trims)
5. **Strong Towing and Hauling Capabilities**
- **Diesel models (L5P Duramax):** Up to **9,600 lbs** towing (with proper equipment) and **12,000 lbs** max payload.
- **Gas models (5.3L V8):** Up to **8,400 lbs** towing and **6,000 lbs** payload.
This makes them suitable for heavy-duty work, towing trailers, or carrying large loads.
6. **Manual Power Steering Column (Advantages)**
- **Easier to Replace Parts:** Manual steering columns are simpler and cheaper to repair or upgrade compared to electric-assisted columns.
- **Better for Off-Roading:** Some drivers prefer the feel of a manual column for better feedback and control in rough terrain.
- **Compatibility with Aftermarket Mods:** Easier to install aftermarket steering wheel covers, switches, or upgrades.
- **Less Risk of Electronic Failure:** Electric steering systems can fail due to software glitches or sensor issues, whereas manual systems are mechanically reliable.
7. **Available in Multiple Engine Options**
- **Diesel (Duramax L5P):** Best for high towing, fuel efficiency ( 15 20 MPG combined), and longevity.
- **Gas (5.3L V8 or 3.7L V6):** More power (especially the 5.3L) but lower fuel economy ( 15 20 MPG combined).
- **Hybrid Option (2017 2019):** The **Duramax Hybrid** (if available) offers better MPG ( 20 25 MPG) but may have higher maintenance costs.
8. **Strong Aftermarket Support**
- Parts, accessories, and modifications (lift kits, exhaust, suspension upgrades) are widely available.
- Many performance and off-road communities support this generation.
9. **Good Safety Ratings**
- The Sierra 1500 has received **IIHS Top Safety Pick ** awards in some years for its crash test performance.
- Features like **stability control, traction control, and multiple airbag options** are standard or available.
10. **Potential for Lower Purchase Price**
- Since these are mid-generation models (not the latest), they may be priced lower than 2020 trucks while still offering strong value.

#### **Cons**
1. **Manual Power Steering Column (Disadvantages)**
- **Less Convenience:** Adjusting the steering wheel height requires manual effort (no electric memory settings).
- **Potential for Wear:** Over time, the manual column can develop stiffness or binding, requiring lubrication or replacement.
- **Less Customization:** Some drivers prefer electric columns for features like one-touch steering wheel adjustments.
2. **Fuel Economy Limitations (Especially Gas Models)**
- **5.3L V8 gas engine:** 15 18 MPG combined (poor compared to modern trucks).
- **3.7L V6 gas engine:** 18 22 MPG combined (better but still not great).
- **Diesel models:** 15 20 MPG combined (better than gas but still not as efficient as newer diesels).
3. **Outdated Infotainment System**
- The **Uconnect system** (depending on the year) can be slow, glitchy, or lack modern features like wireless Apple CarPlay/Android Auto (though some models have USB-based integration).
- Screen quality and navigation accuracy may not be as smooth as newer trucks.
4. **Rust Concerns (Especially in Snowy/Coastal Areas)**
- Some 2014 2019 GM trucks have reported **roof rack rust** and **wheel well corrosion** in certain regions.
- Always inspect the **roof rails, wheel arches, and undercarriage** before purchasing.
5. **Transmission Issues (Especially 6-Speed Automatic)**
- Some owners report **rough shifting, delayed engagement, or transmission fluid leaks** in the **6-speed automatic** (common in gas models).
- Diesel models with the **6L90 transmission** are generally more reliable but can still develop problems if not maintained properly.
6. **Higher Maintenance Costs Over Time**
- **Diesel models:** Require **expensive fuel filters, EGR coolers, and DPF/DEF maintenance** (if equipped).
- **Gas models:** **Timing belt replacement** (every 100K miles) and **coolant system flushes** can add up.
- **Exhaust and suspension wear** is common in high-mileage examples.
7. **Less Advanced Driver Assistance**
- Features like **adaptive cruise control, lane-keep assist, and automatic emergency braking** are either **limited or not available** compared to newer models.
- **Blind-spot monitoring** is rare in this generation.
8. **Comfort and Noise Levels**
- Some owners report **wind noise** at highway speeds, especially on higher-mileage examples.
- **Cab insulation** is decent but not as refined as newer trucks with better soundproofing.
9. **Recall and Warranty Issues**
- Some models may have **unresolved recalls** (check the **NHTSA website** before buying).
- **Extended warranties** (if available) may not cover all potential issues.
10. **Potential for Hidden Problems**
- **Water pump failure** (especially in V8 engines) can lead to **overheating and engine damage**.
- **Turbocharger issues** (in diesel models) can be costly to repair.
- **Suspension wear** (shocks, struts, bushings) is common in high-mileage trucks.

### **Key Considerations Before Buying**
1. **Engine Choice Matters Most**
- **Diesel (Duramax L5P):** Best for towing, longevity, and fuel efficiency (if you drive mostly highway).
- **Gas (5.3L V8):** Best for power and torque (if you need raw towing power).
- **Gas (3.7L V6):** Best for fuel economy (if you don t need heavy towing).
2. **Transmission Reliability**
- **6-speed automatic (gas models):** Check for smooth shifting; avoid if it has a history of rough engagement.
- **6L90 transmission (diesel models):** More durable but still requires proper fluid changes.
3. **Maintenance History**
- **Oil changes (every 5K 7.5K miles for diesel, 5K for gas).**
- **Timing belt replacement (every 100K miles for gas V8).**
- **Coolant system flush (every 100K miles).**
- **DEF/DPF maintenance (if diesel).**
4. **Test Drive Essentials**
- Check for **unusual noises** (knocking, rattling, whining).
- Test **brakes, steering, and suspension** for smoothness.
- Verify **all electronics** (lights, windows, infotainment).
- Ensure **no fluid leaks** (oil, coolant, transmission fluid).
5. **Inspection for Rust and Damage**
- **Roof rails, wheel wells, and undercarriage** (especially if bought in a snowy/salty region).
- **Frame rust** (critical for structural integrity).
- **Exhaust system** (rust can cause leaks).
6. **Budget for Repairs**
- **Diesel models:** Expect **higher long-term costs** (f
