### **Cons of Buying a W167 GLE 350/450 (Especially with Fuel Vent Hose Issues)**

1. **Fuel Gas Tank Vent Hose/Tube/Pipe Problem (Primary Concern)**

- **Fuel smell** in the cabin or engine bay (indicating a leak).

- **Poor fuel economy** due to improper venting.

- **Hard starts or stalling** in extreme cases.

- The **plastic or rubber vent hose** connecting the fuel tank to the EVAP system can **crack, harden, or detach** over time, especially in hot climates.

- **OEM hoses may degrade faster** than aftermarket replacements.

- **Labor:** $150 $300 (depending on dealership vs. independent shop).

- **Parts:** $50 $200 (OEM vs. aftermarket).

- **Potential additional issues** if the hose fails completely (e.g., fuel leaks requiring tank replacement, which can cost **$1,500 $3,000**).

- More common in **higher-mileage models (50K miles)** but can occur earlier in hot or humid climates.

- **High demand for used luxury SUVs** could lead to **higher purchase prices** for well-maintained examples.

### **Key Considerations Before Buying**

1. **Inspect the Fuel Vent Hose Thoroughly**

- **Check for cracks, leaks, or detachment** at the fuel tank, EVAP canister, and intake manifold connections.

- **Scan for CEL codes** (P0446, P0455, etc.) and verify if they ve been properly repaired.

- **Ask for service records** if the hose was replaced, ensure it was done with **OEM or high-quality aftermarket parts**.

2. **Test Drive and Listen for Fuel Smells**

- A **fresh fuel smell** in the cabin or engine bay is a **red flag**.

- **Accelerate hard** to see if the engine runs smoothly stumbling could indicate a venting issue.

3. **Get a Pre-Purchase Inspection (PPI)**

- **Fuel system integrity** (hoses, tank seals, EVAP canister).

- **Engine performance** (no misfires, smooth power delivery).

- **Electrical components** (MBUX system, sensors, wiring).

4. **Negotiate Based on Known Issues**

- If the **fuel vent hose has been replaced**, use that as leverage to **lower the price**.

- If the issue is **unrepaired**, walk away unless the seller offers a **significant discount** or **warranty coverage**.

5. **Consider Alternatives**

- **BMW X5 (F90)** Similar luxury, slightly better resale, but higher maintenance costs.

- **Audi Q7 (4K)** More refined ride, but **Quattro AWD issues** are a concern.
