### **Pros and Cons of Buying a 2008 2012 Infiniti EX35/EX37/QX50 (2012) with the Specified Roof Handle (73940JN21A)**
#### **Pros**
1. **Reliability and Durability**
- The **Infiniti EX35/EX37 (2008 2012)** and **QX50 (2012)** are based on the **Nissan CVT platform**, which, while not as refined as traditional automatics, is generally reliable if maintained properly. The **2012 QX50** (a newer model) benefits from minor refinements over the EX35/EX37.
- The **CVT transmission** is smooth in modern iterations, but older models (pre-2012) may require **fluid changes every 30K 60K miles** to prevent premature wear.
- The **roof handle (73940JN21A)** is a standard **power moonroof** (if equipped), which adds convenience and resale value.
2. **Comfort and Ride Quality**
- The **EX35/EX37** offers a **spacious, upscale interior** with good sound insulation, making for a **quiet cabin** a rare trait in CVT-equipped cars.
- The **QX50 (2012)** improves upon this with a **more refined suspension** and better build quality compared to the older EX models.
- **Comfortable seating** (especially in the EX37) and **standard power features** (power windows, locks, seats) enhance usability.
3. **Fuel Efficiency (For Its Class)**
- The **EX35 (3.7L V6)** gets ** 16 18 MPG combined**, while the **EX37 (3.7L V6 with VDC)** is similar.
- The **QX50 (2012, 3.7L V6)** is slightly more efficient ( 17 19 MPG) due to minor refinements.
- **CVT transmission** improves fuel economy over traditional automatics, though it may not match a manual or dual-clutch setup.
4. **Resale Value and Brand Perception**
- Infiniti has historically held its value better than some Japanese brands, though it has fallen behind in recent years.
- The **QX50 (2012)** is a **more modern SUV** with a **cleaner design** than the older EX models, which may appeal to buyers looking for a **compact luxury SUV**.
- The **moonroof (if equipped)** is a **desirable feature** that can improve resale value.
5. **Available Features (Depending on Trim)**
- **EX35/EX37 (2008 2012):**- **Leather upholstery, heated seats, Bluetooth, backup camera (later models), and available navigation.**
- **EX37** includes **VDC (Vehicle Dynamic Control)** for better handling.
- **QX50 (2012):**- **More modern infotainment (if equipped), better sound system, and improved safety tech (like stability control upgrades).**
- **Available 8-inch touchscreen (in higher trims).**
6. **Affordability (Used Market)**
- These models are **cheaper than luxury competitors** (e.g., BMW 3 Series, Audi A4) in the used market.
- The **QX50 (2012)** is **more desirable** than older EX models due to its **SUV practicality and modern styling.**
---
#### **Cons**
1. **CVT Transmission Concerns**
- **Older CVTs (pre-2012) are prone to failure** if not maintained properly (fluid changes are **critical**).
- **Symptoms of CVT failure:** rough shifting, overheating, slipping, or **complete transmission lockup.**
- **Repair costs can be high** ($2,000 $4,000 for a rebuild or replacement).
- **2012 models improve slightly**, but the **QX50 s CVT is still not as robust as a traditional automatic.**
2. **Reliability Issues with the 3.7L V6**
- The **3.7L V6 (used in EX35/EX37/QX50)** is **notoriously weak** on timing chain tensioners, leading to **chain stretch or failure ( 80K 120K miles).**
- **Symptoms:** rattling under acceleration, misfires, or **complete engine failure if ignored.**
- **Repair is expensive ( $1,500 $2,500)** and often requires **rebuilding or replacing the timing chain kit.**
- **Later models (2012 ) may have slight improvements**, but the **3.7L remains a weak point.**
3. **Infotainment and Tech Limitations**
- **EX35/EX37 (2008 2012) have outdated infotainment** (CD/USB only, no Apple CarPlay/Android Auto).
- **QX50 (2012) improves slightly** with a **better display in some trims**, but still **lagging behind competitors.**
- **Bluetooth is basic** (no wireless, limited audio streaming in older models).
4. **Safety Ratings (Older Models)**
- **EX35/EX37 (2008 2012) lack modern safety tech** (no automatic emergency braking, poor NHTSA ratings).
- **QX50 (2012) is slightly better** with **stability control and side airbags**, but still **not as safe as modern luxury SUVs.**
5. **Maintenance Costs**
- **CVT fluid changes are mandatory** ( $200 $400 every 30K 60K miles).
- **Timing chain replacement is inevitable** ( $1,500 $2,500).
- **Oil changes should be done every 5K 7.5K miles** (CVT oil is thicker and requires frequent changes).
- **Brake pads and rotors wear faster** than in traditional automatic cars due to CVT torque converter limitations.
6. **Depreciation and Market Demand**
- **Infiniti has lost brand prestige** compared to Lexus, Acura, or German brands.
- **EX35/EX37 are less desirable** than the **QX50 (2012)**, which is **more practical as an SUV.**
- **Moonroof-equipped models hold value better**, but **general demand is declining.**
7. **Handling and Driving Experience**
- **EX35/EX37 feel sluggish** due to the **CVT and heavy weight.**
- **QX50 improves slightly** but still **lacks the precision of a BMW or Audi.**
- **Rear-wheel-drive models (EX37) handle better** than FWD (EX35), but **not sporty.**
