Review BUICK 3.6l Engine Throttle Body Oem Miles fits ENCLAVE 2012–2016

The **Buick 12682172BA Throttle Body Assembly** is a precision-engineered component designed exclusively for the **2013 2015 Buick Enclave** models equipped with the **3.6L Ecotec V6 engine**, ensuring optimal airflow and performance for this popular luxury crossover SUV. This high-quality throttle body is engineered to maintain consistent throttle response, enhance fuel efficiency, and reduce emissions by precisely controlling the intake air entering the engine s intake manifold. Crafted from durable materials, including a robust plastic housing and a responsive electronic actuator, this throttle body integrates seamlessly with the vehicle s **EFI (Electronic Fuel Injection) system**, allowing for smooth acceleration and reliable operation under varying driving conditions. The design incorporates a **pulse-width modulation (PWM) control system**, which adjusts the throttle position dynamically based on input from the engine control module (ECM), ensuring precise engine management for both idle stability and high-performance demands. Whether used for routine maintenance, replacement after wear or failure, or as part of a performance upgrade, this throttle body is a critical component that helps sustain the Enclave s signature blend of comfort, power, and efficiency. Its compatibility with the **GM 3.6L V6 engine** commonly found in the 2013, 2014, and 2015 model years makes it an essential aftermarket or OEM replacement part for owners seeking to restore or enhance their vehicle s drivability and longevity.

Buying a **2013-2015 Buick Enclave with a 3.6L engine and throttle body issues** requires careful consideration due to the vehicle s age, potential reliability concerns, and the specific throttle body problem. Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.

---

### **Pros of Buying a 2013-2015 Buick Enclave (3.6L Engine)**

1. **Spacious and Comfortable Interior**

The Enclave is a midsize luxury SUV with a roomy cabin, offering comfortable seating for five or six passengers. The interior materials are relatively upscale compared to many competitors in its class, with available leather upholstery, heated/ventilated seats, and a quiet cabin.

2. **Strong and Reliable 3.6L V6 Engine**

The 3.6L F23 engine (a General Motors Ecotec) is a well-regarded inline-six that produces **288 hp and 262 lb-ft of torque**, providing smooth power delivery and adequate performance for highway driving and towing (up to **3,500 lbs** with the proper tow package). This engine is known for its longevity when maintained properly, with many examples lasting **200,000 miles** with basic upkeep.

3. **Good Fuel Economy for a SUV**

- **City:** 16-18 MPG

- **Highway:** 24-26 MPG

This is better than many competitors like the Chevrolet Traverse or Ford Explorer, though not as efficient as smaller luxury SUVs like the Lexus RX.

4. **Smooth Transmission Options**

The Enclave comes with either a **6-speed automatic (6T70)** or **6-speed automatic with manual shift (6T75)**, both of which are reliable and provide smooth gear shifts when properly maintained. The 6T75 is preferred for its better towing capability and more precise control.

5. **Luxury Features and Tech for the Time**

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

- **Heated/ventilated front seats**

- **Leather-trimmed interior**

- **Available sunroof and rear-seat entertainment**

- **Standard stability control and multiple airbags**

While the Uconnect system can be clunky by modern standards, it was advanced for its time.

6. **Resale Value and Brand Reputation**

Buick has historically held its value better than some domestic brands, and the Enclave was a solid choice for families seeking a premium SUV. The brand has improved its reliability over the years, and the Enclave s design was well-received for its practicality.

7. **Low-Cost Maintenance Compared to Luxury Brands**

Routine maintenance (oil changes, brake jobs, etc.) is significantly cheaper than for German or Japanese luxury SUVs. Major repairs (if needed) are also more affordable than on high-end competitors.

8. **Good Towing and Hauling Capacity**

With the proper package, the Enclave can tow up to **3,500 lbs**, making it suitable for small trailers, boats, or heavy-duty tasks. The **6T75 transmission** handles towing better than the standard 6T70.

9. **Available AWD (All-Wheel Drive)**

The **AWD option** provides better traction in snow and wet conditions, which can be valuable depending on your climate.

10. **Proven Reliability in Some Cases**

Many 2013-2015 Enclaves with proper maintenance have lasted well beyond **150,000 miles**. The 3.6L engine is robust, and the SUV s design is simple enough to avoid many common failure points seen in more complex vehicles.

### **Cons of Buying a 2013-2015 Buick Enclave (3.6L Engine, Throttle Body Issues)**

1. **Throttle Body Problems (Major Concern)**

The **throttle body** in these Enclaves (and other GM vehicles from this era) is notorious for **carbon buildup, sticking, or complete failure**, leading to:

- **Rough idling, stalling, or hesitation**

- **Check Engine Light (P0120, P0121, P0122, P0123 codes)**

- **Poor acceleration or surging**

- **Difficulty starting the engine**

The throttle body is an **electronic throttle control (ETC) system**, and the failure is often due to **carbon deposits** that prevent the throttle plate from opening smoothly. This issue is **common in GM vehicles from 2010-2015** and can be expensive to fix if not addressed early.

- **Cost to replace:** $300-$600 (parts and labor)

- **Prevention:** Regular **throttle body cleanings** (every 30,000-50,000 miles) can extend its life, but many owners neglect this until failure occurs.

2. **Transmission Issues (Especially 6T70)**

Some owners report **rough shifting, delayed engagement, or complete failure** of the **6-speed automatic transmission (6T70)**. While not as common as the throttle body issue, it is a **known weakness** in this era of GM transmissions.

- **Symptoms:** Jerky shifts, slipping, or failure to downshift properly.

- **Cost to repair:** Transmission rebuild or replacement can cost **$3,000-$6,000 **, depending on labor rates.

3. **Oil Leaks (Valvetrain Cover Gasket)**

The **valvetrain cover gasket** is a **common leak point** in the 3.6L engine, leading to oil spots under the vehicle. If ignored, this can lead to **low oil pressure and engine damage**.

- **Cost to fix:** $200-$400 (parts and labor).

4. **Exhaust Manifold Gasket Failure**

The **exhaust manifold gaskets** can fail, causing **exhaust leaks and a hissing noise**. This is more common in the **2013-2014 models** than the 2015.

- **Cost to fix:** $300-$600 (parts and labor).

5. **Electrical Gremlins (Uconnect System)**

The **Uconnect infotainment system** can be **glitchy, slow to respond, or fail entirely**. Software updates were released to fix some issues, but older models may still suffer from **Bluetooth connectivity problems, touchscreen lag, or complete system lockups**.

- **Cost to repair:** $200-$500 for diagnostics or replacement.

6. **Rust Concerns (Especially in Snowy Climates)**

The Enclave s **wheel wells, rocker panels, and undercarriage** are prone to **rust**, particularly in areas with **salted roads**. A thorough inspection is **essential** before purchase.

7. **Tire and Suspension Wear**

As a **larger SUV**, the Enclave has **higher tire wear** and **suspension components** (shocks, struts, bushings) that may need replacement if the vehicle has high mileage. The **front struts** are known to wear out around **100,000 miles**.

8. **Recall and Unresolved Issues**

- **Airbag deployment issues**

- **Fuel pump failures**

- **Transmission control module problems**

Always check the **NHTSA recall database** before purchasing.

9. **Depreciation and Market Value**

The Enclave has **depreciated significantly** since its peak, and finding **reliable used examples** can be challenging. Many potential buyers may opt for **newer or more proven SUVs** (e.g., Toyota Highlander, Honda Pilot, or Lexus RX).

10. **Potential Hidden Major Repairs**

- **Water pump failure** ( $1,000-$1,500)

- **Timing chain stretch** (less common in the 3.6L but possible)

- **Front differential issues** (in AWD models)

- **A/C compressor failure** ( $800-$1,200)

---

### **Key Considerations Before Buying**

1. **Throttle Body Inspection**

- **Ask for maintenance records** to confirm if the throttle body has been **cleaned or replaced**.

- **Test drive the vehicle** and listen for **rough idling, stalling, or hesitation**.

- **Check for active or past "Check Engine" codes** (P0120-P0123 are throttle-related).

- **If the throttle body is failing**, factor in **
