### **Pros and Cons of Buying a 2011 2015 Infiniti QX56/QX80 (5.6L V8) with Ending Cylinder Head Camshafts**

1. **Strong Engine Performance** The 5.6L V8 (VQ35DE) is a robust, turbocharged engine capable of producing around **400 450 hp** (depending on tuning and modifications). It offers strong towing capacity and spirited acceleration, making it suitable for those who want a powerful luxury SUV.

2. **Luxury and Comfort** The QX56/QX80 is a premium vehicle with high-end interior materials, advanced infotainment (in later models), and a smooth ride, making it a comfortable choice for long drives.

3. **Spacious Interior** The cabin is roomy, with ample seating for five (or six in some trims) and a large cargo area, making it practical for families or those needing extra space.

4. **Reliability (When Well-Maintained)** The VQ35DE engine, when properly maintained, can last well beyond 200,000 miles. Many owners report few major issues if the vehicle has been serviced regularly.

5. **Aftermarket Support** The 5.6L V8 has a strong aftermarket following, with readily available parts, upgrades (turbo kits, exhaust, intake), and tuning solutions for those looking to enhance performance.

6. **Resale Value (Compared to Competitors)** While not as high as some German luxury SUVs, the Infiniti brand still holds decent resale value, especially for well-documented examples.

7. **All-Wheel Drive (AWD)** The standard AWD system provides good traction in various conditions, making it a practical choice for drivers in snowy or wet climates.

1. **Ending Cylinder Head Camshafts (Camshaft Failure Risk)** The most critical issue with these engines is the **camshaft failure** in the cylinder heads, which can occur due to **camshaft journal wear, improper lubrication, or lack of maintenance**. This can lead to catastrophic engine failure if not addressed early. Some owners report hearing a **whining or grinding noise** before failure, but others experience sudden breakdowns.

2. **High Repair Costs** Replacing camshafts or repairing cylinder heads can be **expensive (often $2,000 $4,000 )** due to labor and parts. Some owners opt for **remanufactured heads** or **full engine rebuilds**, which further increase costs.

3. **Turbocharger Reliability** The turbocharged VQ35DE is prone to **turbo failure** if not maintained properly (oil changes, cooling system upkeep). A failed turbo can cost **$1,500 $3,000 ** to replace.

4. **Transmission Issues** Some owners report **rough shifting, delayed engagement, or transmission fluid leaks** in the 6-speed automatic. A transmission rebuild can be costly.

5. **Fuel Economy Concerns** The 5.6L V8 is not fuel-efficient, averaging **14 16 MPG combined**, which can be expensive to operate over time.

6. **Electrical Gremlins** Like many luxury vehicles, the QX56/QX80 has had reports of **electrical issues** (window regulators, sensors, infotainment glitches), which can be frustrating to diagnose and repair.

7. **Depreciation** Luxury SUVs depreciate quickly, and the Infiniti brand, while improving, still doesn t hold value as well as some German or Japanese competitors.

8. **Recall and Warranty Issues** Some early models had **unresolved recalls** (e.g., fuel pump, airbag, or electrical issues). Always check for open recalls before purchasing.

---

- You **prioritize performance and luxury** over fuel efficiency.

- You **plan to maintain the vehicle well** (regular oil changes, cooling system checks, turbo monitoring).

- You **budget for potential camshaft or turbo repairs** (or are prepared to replace the engine if needed).

- You **find a well-documented example** with **service records** showing no camshaft issues.

However, if you **cannot afford unexpected engine repairs** or **prefer a more reliable, lower-maintenance luxury SUV**, this may not be the best option. Consider alternatives like:

- A **2012 Lexus LX570** (more refined, better reliability).

- A **2013 BMW X5 3.0i** (strong engine, better resale).

- A **2014 Audi Q7 3.0T** (turbo V6, more efficient than the V8).

---

1. **Get a pre-purchase inspection (PPI) from a VQ35DE specialist** They can check for **camshaft wear, turbo condition, and cylinder head integrity**.

2. **Request full service records** Look for **oil change intervals, cooling system flushes, and any past camshaft or turbo work**.

3. **Budget for the worst-case scenario** Assume you may need to **replace camshafts or the turbo within the next 50,000 100,000 miles**.

4. **Consider a remanufactured engine or cylinder heads** If the current engine has significant wear, a **remanufactured VQ35DE** ( $5,000 $7,000) may be a better long-term investment.

5. **Avoid high-mileage examples without proof of maintenance** A **well-kept 80,000-mile QX56** is preferable to a **150,000-mile one with no service history**.

**Final Verdict:** This is a **high-reward, high-risk purchase**. If you re **mechanically inclined, financially prepared for repairs, and love the performance**, it can be a fantastic vehicle. Otherwise, consider a more reliable luxury SUV alternative.
