Review MASERATI Power Steering Gear Rack And Pinion fits QUATTROPORTE 2005–2019

The **Maserati 1739202 OEM Power Steering Gear Rack and Pinion Assembly (M139, 2008 2019 Quattroporte)** is a precision-engineered component designed to deliver the effortless, responsive, and luxurious steering dynamics that define the iconic Maserati Quattroporte. This high-performance rack and pinion system is integral to the vehicle s refined handling, ensuring smooth, linear feedback and minimal play while maintaining the brand s signature blend of Italian craftsmanship and cutting-edge automotive technology. Crafted from durable, corrosion-resistant materials and engineered to exacting specifications, this rack and pinion assembly features a robust helical gear design optimized for longevity and reliability, even under the demanding conditions of spirited driving or prolonged use on varied road surfaces. The pinion, machined from hardened steel, meshes seamlessly with the rack s precision-cut teeth, reducing friction and backlash while enhancing steering precision and reducing the effort required to maneuver the vehicle. This assembly is specifically tailored for the **M139 platform**, which underpins the Quattroporte from 2008 through 2019, ensuring a perfect fit with the vehicle s suspension geometry, steering column, and tie rod linkages. Whether restoring a classic Quattroporte to its original glory or upgrading an existing system for improved performance, this OEM replacement part guarantees the same level of performance and refinement as the factory-equipped component, with the added assurance of genuine Maserati quality. Its seamless integration with the vehicle s hydraulic or electric power steering system (depending on the model year) ensures consistent, predictable steering response, even at high speeds or during aggressive cornering, embodying the Quattroporte s reputation for both elegance and performance.

### **Pros and Cons of Buying a Maserati Quattroporte (M139, 2008 2019) with Power Steering Gear Rack, Pinion**

#### **Pros**

1. **Luxury and Prestige** The Quattroporte is one of Maserati s most iconic grand tourers, offering a blend of Italian design, refined interiors, and a commanding presence. Its V8 engine (initially the 4.2L, later the 4.7L) delivers a smooth, engaging driving experience with strong performance.

2. **Strong Engine Options** The M139 platform introduced a more powerful and modern engine (4.7L V8) in later models, producing around **450 500 hp** (depending on trim) with excellent torque. Earlier 4.2L models are still capable but slightly less refined. The engine is paired with a **6-speed automatic transmission**, which, while not the smoothest, is reliable when maintained.

3. **Comfort and Ride Quality** The Quattroporte is built on a solid platform with good suspension tuning, offering a **luxurious, well-insulated cabin** that absorbs road imperfections well. The seats are supportive yet plush, making long drives comfortable.

4. **Aesthetic Appeal** The design remains timeless, with sharp lines, aggressive front grille, and a commanding silhouette. The **LED headlights (on later models)** and available **carbon fiber accents** add to its premium look.

5. **Resale Value (Compared to Peers)** While not as high as a Ferrari or Lamborghini, the Quattroporte holds its value better than many luxury sedans due to its brand prestige and limited production numbers.

6. **Tech and Features (Later Models)** The **2012 facelift models** introduced improvements like **Brembo brakes, adaptive suspension, and a more refined infotainment system** (though still basic by modern standards). Some models come with **heated/cooled seats, leather-trimmed interiors, and ambient lighting**.

7. **Driving Dynamics** The Quattroporte is **more engaging than a typical luxury sedan**, with a well-balanced chassis, precise steering (especially with power assist), and a **direct, engaging driving experience** that appeals to enthusiasts.

8. **Availability of Parts and Support** As a Maserati, it benefits from **official dealer networks** (though service can be expensive). The M139 platform is well-documented, and aftermarket support exists for common issues.

#### **Cons**

1. **High Maintenance and Repair Costs** Maserati is a luxury brand, and **labor and parts are expensive**. Routine maintenance (oil changes, brake jobs, suspension work) can cost **$1,000 $3,000 per year** if done at a dealer. Independent mechanics may offer better rates but risk voiding warranties.

2. **Reliability Concerns (Especially Early Models)** The **4.2L V8 (pre-2012)** is known for **oil consumption issues, timing chain wear, and electrical gremlins** (e.g., sensor failures, infotainment glitches). The **4.7L V8 (post-2012)** is more refined but still not bulletproof **carbon buildup in intake manifolds, water pump failures, and suspension wear** are common problems.

3. **Transmission Issues** The **6-speed automatic** can be **jerky or slow to shift**, especially in cold weather. Some owners report **clutch or torque converter failures**, which are costly to repair.

4. **Poor Fuel Economy** The V8 engine **averages 12 15 MPG (city/highway)**, making it **expensive to run** compared to modern turbocharged sedans.

5. **Interior Quality (Early Models)** The **pre-2012 interiors** feel **cheap in places**, with **plastic trim, thin padding, and basic sound insulation**. Later models improved with **better materials and noise reduction**, but they still lack the **premium feel of a BMW 7 Series or Mercedes S-Class**.

6. **Comfort vs. Sportiness Trade-Off** While the Quattroporte is **comfortable for cruising**, it is **not as nimble as a Porsche 911 or Audi A8**. The steering is **heavy without power assist** (though the power steering helps), and the **body roll under cornering** is noticeable.

7. **Depreciation** Like most luxury cars, the Quattroporte **loses value quickly**. A well-maintained 2015 model may retain ** 40 50% of its original price**, but this varies based on mileage and condition.

8. **Noise and Vibration Issues** Some owners report **wind noise at high speeds**, **engine cover rattles**, and **road noise penetration** in the cabin, especially in older models.

9. **Limited Aftermarket Support** While not as extreme as a Ferrari, **finding aftermarket parts or tuning solutions** is harder than for a BMW or Mercedes. Modifications (e.g., exhaust, suspension) are **expensive and not always worth it**.

10. **Resale Market Challenges** Finding a **reliable, low-mileage example** can be difficult. Many potential buyers are **turned off by maintenance costs**, making it harder to sell later.

### **Key Considerations Before Buying**

1. **Budget for Maintenance** If you re not prepared for **$10,000 $20,000 in repairs over 5 7 years**, this is not the car for you. **Always get a pre-purchase inspection (PPI) from a Maserati specialist.**

2. **Check Service History** Look for **regular oil changes (every 5,000 7,000 miles)**, **timing chain inspections**, and **suspension work**. A **well-documented car** is far more reliable.

3. **Test Drive for Comfort & Handling**

- Does the **steering feel responsive** (not too heavy)?

- Are there **excessive vibrations** at highway speeds?

- Does the **transmission shift smoothly**, or is it sluggish?

4. **Avoid Early 4.2L Models (Pre-2012)** If possible, **prioritize a 4.7L V8 (2012 )** for better reliability and power. However, even these require **vigilant maintenance**.

5. **Consider Alternatives**

- **BMW 7 Series (F01/F10)** More refined, better tech, and easier to maintain.

- **Mercedes-Benz S-Class (W222/W223)** Superior comfort and reliability.

- **Audi A8 (D4/D5)** More practical, better fuel economy, and easier to work on.

- **Porsche 911 (997/991)** If you want **more driving excitement** without Maserati s maintenance headaches.

---

### **Final Recommendation**

You **prioritize luxury, prestige, and driving enjoyment** over practicality.

You **have a budget for maintenance** (expect **$1,500 $3,000/year** in upkeep).

You **find a well-maintained example** (preferably **2012 with the 4.7L V8**).

You **enjoy the V8 sound and sporty handling** of a grand tourer.

You **plan to keep it for 5 7 years** and are okay with **higher insurance costs**.

You **can t afford unexpected repairs** (common issues include **timing chain, water pump, suspension**).

You **prefer a more reliable luxury sedan** (BMW, Mercedes, Audi).

You **don t want to deal with dealer service costs**.

You **need better fuel economy or practicality** (this is a **luxury cruiser**, not a daily driver).

- **Buy used (2014 2019, 4.7L V8)** from a **trusted dealer or private seller with full service records**.

- **Get a PPI (Pre-Purchase Inspection)** from a **Maserati specialist** to check for **timing chain wear, oil leaks, and suspension issues**.

- **Budget for a full service refresh** (new **oil filter, spark plugs, timing chain inspection, suspension bushings**).

- **Consider financing carefully** these cars **depreciate fast**, and resale value may not cover loan balances.

**Verdict:** The Quattroporte is a **fantastic car for the right owner** someone who appreciates **Italian luxury, V8 power, and a commanding driving experience** while being **financially prepared for its quirks**. However, it is **not a practical or low-maintenance choice** for most buyers. If you re set on a Maserati, **priorit
