### **Pros and Cons of Buying a 2018 2020 Lexus LS500 (3.5L V6 Engine, Crankshaft Considerations)**

#### **Pros**

1. **Premium Build Quality and Reliability**

The Lexus LS500 is built on Toyota s robust platform, known for durability and long-term dependability. The 3.5L V6 engine (a modified version of Toyota s 2GR-FKS) is a refined powerplant with good fuel efficiency for its class and low maintenance requirements compared to some luxury rivals.

2. **Strong Performance and Driving Dynamics**

The LS500 delivers a balanced blend of power (306 362 hp, depending on the year) and smooth acceleration, with precise handling and a comfortable ride. The 8-speed automatic transmission (with paddle shifters in later models) is smooth and responsive.

3. **Luxury and Comfort**

The interior is high-end, with premium materials, quiet cabin acoustics, and advanced features like Lexus s Entune infotainment system (though some users report occasional software glitches). The seating is supportive, and the ride is well-damped, making it comfortable for long drives.

4. **Resale Value**

Lexus vehicles hold their value well, and the LS500 is no exception. Even after a few years, it retains a strong resale price, especially in well-maintained examples.

5. **Low Maintenance Costs (Compared to Competitors)**

Lexus dealerships are known for transparent pricing and competitive service costs. The 3.5L V6 is a relatively simple engine with fewer issues than some German or high-performance luxury engines.

6. **Safety Features**

The LS500 comes standard with Lexus Safety System 2.0, including pre-collision braking, lane-keeping assist, and adaptive cruise control features that enhance both safety and convenience.

7. **Crankshaft Durability**

The 2GR-FKS engine (used in the LS500) has a forged crankshaft, which is more durable than cast crankshafts found in some engines. This reduces the risk of catastrophic failure, though proper maintenance is still critical.

---

#### **Cons**

1. **Higher Upfront Cost**

The LS500 is one of the most expensive Lexus models, with prices ranging from **$40,000 $60,000 ** depending on the year, trim, and mileage. Used examples in good condition can still be pricey, especially in high-demand markets.

2. **Potential Engine and Transmission Issues**

- **3.5L V6 (2GR-FKS) Concerns:**

- Some owners report **oil consumption** (especially in high-mileage examples), which can lead to frequent oil changes.

- **Carbon buildup** in the intake valves may occur, requiring a **carbon cleaning service** (around $500 $800) if symptoms like rough idling or hesitation appear.

- **Timing chain stretch** is rare but possible over very high mileage (150,000 miles), though Lexus does not recommend replacing it proactively.

- **Transmission Issues:**

- Early 2018 models (pre-refresh) had some reports of **rough shifting** or **delayed engagement**, though Lexus addressed this with software updates.

- Later models (2019 2020) improved with smoother transmissions, but some still experience **jerky shifts under load**.

3. **Maintenance Can Be Expensive**

While cheaper than German luxury brands, Lexus parts and labor are not as budget-friendly as Toyota s smaller models. Major services (e.g., valve cover gasket replacement, suspension work) can add up.

4. **Infotainment System Limitations**

The Entune system is functional but lacks the polish of Apple CarPlay/Android Auto. Navigation is decent but not as advanced as some BMW or Mercedes systems. Some users report **slow response times** or **app compatibility issues**.

5. **Rear Seat Comfort and Space**

While spacious, the LS500 s rear seats are **less comfortable for long trips** compared to some rivals (e.g., BMW 7 Series or Mercedes S-Class). Legroom is adequate, but the fixed rear seats lack the reclining luxury of higher-end competitors.

6. **Fuel Economy Trade-offs**

The LS500 is not a fuel-efficient luxury sedan. Expect **16 18 MPG highway** in automatic mode, which is decent but not great for a large V6. Hybrid options (like the Lexus LS 500h) offer better efficiency if that s a priority.

7. **Crankshaft-Specific Risks (If Purchasing a Used Example with Suspected Issues)**

- While the **forged crankshaft** is durable, **excessive wear or damage** (from neglect, oil starvation, or severe misfires) can lead to **engine failure**.

- If buying a used LS500, **check for:**

- **Oil leaks** (valve cover, oil filter housing gasket).

- **Blue smoke from the exhaust** (sign of burning oil).

- **Ticking or rattling noises** (could indicate timing chain or rod bearing issues).

- **Service records** proving regular oil changes (every 5,000 7,500 miles).

8. **Depreciation Over Time**

While Lexus retains value well, the LS500 s premium pricing means it may depreciate faster than more affordable luxury sedans (e.g., Acura TLX, Cadillac CT6).

---

### **Ending Conclusion**

The **2018 2020 Lexus LS500 with a 3.5L V6 engine** is a **strong choice for buyers** who prioritize **luxury, reliability, and driving pleasure** without the complexity of high-performance engines. Its **forged crankshaft, Toyota-built durability, and lower maintenance costs compared to German rivals** make it a practical luxury sedan.

However, **potential buyers should be aware of:**

- **Higher upfront and maintenance costs** than smaller luxury or non-luxury vehicles.

- **Possible engine quirks** (oil consumption, carbon buildup) that require attention.

- **Transmission smoothness variations** (early 2018 models may need software updates).

- **Infotainment limitations** if advanced connectivity is a must.

**If you find a well-maintained LS500 with a clean service history, it is a reliable and enjoyable luxury sedan.** However, if **budget is a concern**, consider alternatives like the **Lexus GS 500 (same engine, lower price)** or a **used BMW 5 Series/7 Series** (if you re okay with higher maintenance risks).

### **Recommendation**

- **Buy if:**

- You want a **luxury sedan with Toyota s reliability** and **low long-term hassles**.

- You can afford **higher upfront and maintenance costs** without hesitation.

- You prioritize **comfort, performance, and resale value** over cutting-edge tech.

- The **crankshaft and engine** have been properly maintained (oil changes, no leaks, no blue smoke).

- **Avoid if:**

- You re on a **tight budget** and can find a well-equipped alternative (e.g., Acura TLX, Genesis G80).

- You **ignore maintenance** this car rewards proper care.

- You **need advanced infotainment** (Entune is functional but not as smooth as CarPlay/Android Auto).

- You **plan to drive over 20,000 miles per year** fuel costs and wear may outweigh savings.

**Final Verdict:** The LS500 is a **solid luxury choice** for those who value **durability, comfort, and prestige** but it s not the best value for every buyer. **Get a pre-purchase inspection, verify service records, and test-drive thoroughly** before committing.
