### **Pros and Cons of Buying a 2013 Infiniti G37 (400-62462, LKQ436155746, 3.7L V6, Automatic Transmission)**

1. **Reliability and Durability** The 3.7L V6 engine (VQ37VHR) is a well-regarded Infiniti/Nissan powerplant known for longevity when properly maintained. Many examples with 100,000 miles run smoothly if service records are available.

2. **Comfortable Ride** The G37 is designed for a smooth, quiet cabin, making it ideal for highway driving and long trips. The suspension is well-tuned for comfort rather than sportiness.

3. **Good Fuel Economy** For a V6 sedan, it offers decent efficiency, averaging around **18-20 MPG city / 26-28 MPG highway** when driven conservatively. Better than many comparable luxury sedans from the same era.

4. **Spacious Interior** The cabin is roomy, with a comfortable front bench and decent rear legroom. The infotainment system (if equipped with the optional navigation) is functional for its time.

5. **Resale Value** Infiniti sedans from this era hold value reasonably well, especially if well-maintained. The G37 is less common than some competitors, which could be an advantage if you want something unique.

6. **Available Luxury Features** Depending on trim, options include leather seats, heated/ventilated front seats, power-adjustable seats, a premium sound system, and available navigation.

7. **Proven Transmission** The **Jatco JF515E automatic** (a 5-speed) is a robust unit when maintained. Common issues (like delayed shifts) are often fixable with a transmission fluid flush or minor adjustments.

8. **Lower Purchase Price** As a used luxury sedan, the G37 is often priced competitively compared to BMW 5-Series or Mercedes E-Class equivalents from the same era.

---

1. **Aging Infotainment System** The **iDrive-style touchscreen (if equipped)** can be slow and outdated by modern standards. Some models lack Bluetooth or Apple CarPlay/Android Auto.

2. **Maintenance Costs** While the engine is reliable, **Nissan/Infiniti dealership labor rates are high**, and parts (especially for suspension, brakes, and electronics) can be expensive. Independent mechanics may not be as familiar with Infiniti-specific repairs.

3. **Transmission Issues (Potential)**

- Some G37s develop **rough shifting, delayed engagement, or slipping** over time, often due to **low-quality transmission fluid or lack of maintenance**.

- A **transmission fluid flush** (around **$200-$400**) may be needed if the fluid is dark or burnt.

- The **torque converter** can fail, leading to **hard shifting or no engagement** a costly repair ( $1,500 ).

4. **Suspension Wear** Many G37s develop **stiff or clunky suspension** due to worn struts, bushings, or ball joints. A **suspension inspection** ( $200-$500) is recommended before purchase.

5. **Rust Concerns** If the car has seen **salt exposure or poor storage**, check for **rust in the wheel wells, rocker panels, and undercarriage**. Rust can lead to structural issues over time.

6. **Power Steering Problems** Some G37s develop **leaking or failing power steering pumps**, causing **hard steering or whining noises**. Replacement pumps can cost **$500-$1,000**.

7. **Electrical Gremlins** Infiniti s wiring harnesses can degrade over time, leading to **intermittent issues with lights, windows, or sensors**. A **full electrical system check** is wise.

8. **Limited Aftermarket Support** Finding **OEM or high-quality aftermarket parts** (e.g., brakes, filters) can be harder than for more common brands like Toyota or Honda.

9. **Depreciation** While it holds value better than some competitors, luxury sedans from this era still depreciate significantly. If you plan to keep it long-term, factor in **ongoing maintenance costs**.

10. **Safety Ratings** The G37 does not have the latest **IIHS Top Safety Pick** ratings. While it s not unsafe, newer models would offer better crash protection.

### **Key Pre-Purchase Inspection Checklist**

**Transmission fluid** Should be **red and clear** (not burnt or dark).

**Suspension components** Check for **worn struts, bushings, or ball joints**.

**Power steering fluid** Should be **clean and at proper level**.

**Brake system** Look for **thin pads, warped rotors, or leaking calipers**.

**Electrical system** Test **all lights, windows, sensors, and infotainment**.

**Underbody for rust** Especially in **wheel wells, frame rails, and subframe**.

**Service records** Proof of **oil changes, transmission fluid flushes, and major services**.

**Test drive** Listen for **unusual noises (whining, grinding, clunking)** and check for **smooth shifting**.

---

### **Conclusion & Recommendation**

You **prioritize reliability over cutting-edge tech** and are willing to **budget for maintenance**.

You **prefer a comfortable, quiet sedan** for **daily driving and highway use**.

You **find a well-documented example** with **clean service records** and a **mechanic s pre-purchase inspection**.

You **don t mind occasional quirks** (e.g., outdated infotainment) in exchange for **V6 power and luxury seating**.

You **need the latest tech** (Apple CarPlay, advanced safety features, modern infotainment).

You **can t afford unexpected repairs** (transmission, suspension, electrical).

The car has **no service history** or **visible rust/corrosion**.

You **find better alternatives** (e.g., a **2014 Infiniti Q50, BMW 530i, or Lexus ES 350**) at a similar price with fewer issues.

The **2013 Infiniti G37 is a solid choice if you find a **well-maintained example** with a **clean transmission and suspension**. It offers **reliable V6 power, a comfortable ride, and decent fuel economy** but **only if you re prepared for potential aging issues and higher maintenance costs than a Toyota or Honda**.

- **Get a pre-purchase inspection** (costs **$100-$200** but saves thousands).

- **Verify transmission fluid condition** (flush if needed).

- **Check for rust and suspension wear**.

- **Negotiate price based on inspection findings** (common issues can drop value by **$1,000-$3,000**).

If all checks out, the G37 can be a **great used luxury sedan** but if you re unsure about maintenance, consider a **more modern Infiniti (Q50, Q60) or a well-documented BMW/Mercedes alternative**.
