### **Pros and Cons of Buying a BMW E65/E66 750i/750li (2006 2008) with a Power Steering Gear Rack/Pinion Issue**

#### **Overview**

The BMW E65/E66 750i/750li (2006 2008) is a luxury sedan powered by the twin-turbocharged V12 (7.0L) or V8 (5.0L in the 750i), producing 507 550 hp. While these models are iconic, they come with unique challenges, particularly regarding the power steering gear rack and pinion. Below is a detailed breakdown of their advantages and drawbacks.

---

### **Pros**

1. **Exceptional Performance and Power**

- The twin-turbo V12 (760i) and V8 (750i) deliver breathtaking acceleration, with the V12 capable of 0-60 mph in under 4.5 seconds. The 750i (V8) is slightly less powerful but still rapid.

- Smooth, linear power delivery with minimal turbo lag when properly maintained.

2. **Luxury and Comfort**

- High-end interior with premium materials, heated/ventilated seats, and advanced infotainment (for its time).

- Quiet cabin, especially with the V12 s low-end torque.

- Comfortable ride with adaptive damping (optional).

3. **Reliability of Core Components**

- The V12 and V8 engines are robust if maintained properly. Common issues (like oil leaks or turbo failures) are manageable with regular servicing.

- The transmission (ZF 8HP automatic) is durable but requires proper fluid changes.

4. **Resale Value and Prestige**

- BMW s luxury status ensures these models retain value better than many competitors.

- Collectible status for enthusiasts, especially low-mileage examples.

5. **Aftermarket Support**

- Strong aftermarket community for performance upgrades (exhaust, suspension, tuning) and restoration parts.

- Availability of OEM and aftermarket power steering racks/pinions for replacement.

---

### **Cons**

1. **Power Steering Gear Rack/Pinion Failure**

- **Common Issue:** The hydraulic power steering rack/pinion in these models is notorious for failing prematurely, often between **80,000 120,000 miles**. Symptoms include:

- Heavy steering effort.

- Whining or grinding noises.

- Vibrations in the steering wheel.

- Complete loss of power assist (requiring manual effort to steer).

- **Cost of Repair:** Replacing the rack/pinion can cost **$1,200 $2,500 ** depending on labor and whether an OEM or aftermarket part is used. Some owners opt for hydraulic-to-electric conversion kits ( $2,000 $3,500), which improve reliability but add complexity.

2. **High Maintenance Costs**

- **Engine:** Twin-turbo V12s/V8s require frequent **oil changes (every 5,000 7,500 miles)** to prevent sludge buildup. Turbocharger failures are possible if maintenance is neglected.

- **Transmission:** The ZF 8HP automatic needs **fluid changes every 30,000 50,000 miles** to avoid premature wear.

- **Suspension:** Air suspension systems (if equipped) can fail, requiring costly repairs or replacements.

- **Electronics:** Complex infotainment and driver aids (e.g., navigation, adaptive cruise) can be finicky and expensive to repair.

3. **Fuel Economy and Running Costs**

- **Poor MPG:** The V12 averages **12 14 MPG highway**, while the V8 does slightly better ( 14 16 MPG). High fuel consumption adds to ownership costs.

- **Insurance:** Premiums are high due to the car s value and performance capabilities.

4. **Common Wear Items**

- **Brakes:** Carbon-ceramic or high-performance rotors wear quickly and are expensive to replace.

- **Tires:** Premium tires (e.g., Michelin Pilot Sport) are necessary for performance but costly to maintain.

- **Exhaust:** Catalytic converters and mufflers can fail or corrode due to the V12 s high exhaust temperatures.

5. **Age-Related Reliability Risks**

- **Timing Chain:** The V12/V8 uses a timing chain (not a belt), but wear can occur over time, leading to rattling noises or failure.

- **Water Pump:** Often fails around **100,000 miles**, requiring a costly replacement.

- **Coolant System:** Plastic coolant lines and hoses can degrade, leading to leaks.

6. **Driving Experience Quirks**

- **Steering Feel:** A failing rack/pinion can make the car feel unstable, even if the issue isn t severe yet.

- **Noise:** The V12 is loud, especially at highway speeds, and the cabin can feel cramped for tall drivers.

---

### **Key Considerations Before Purchase**

1. **Power Steering Rack/Pinion Condition**

- **Inspect Thoroughly:** Have a trusted mechanic test the rack for play, leaks, or unusual noises. A visual inspection may not reveal internal wear.

- **Budget for Replacement:** If the rack is failing, factor in **$1,500 $3,000** for repair or conversion.

- **Consider Electric Power Steering:** If buying used, look for models that have already undergone an electric conversion (e.g., **Steer-By-Wire or BMW s own system**). This eliminates future rack issues but adds complexity.

2. **Maintenance History**

- **Oil Changes:** Verify frequent oil changes (every 5,000 7,500 miles) to prevent sludge.

- **Transmission Fluid:** Check for recent ZF 8HP fluid changes.

- **Turbo Inspection:** Listen for exhaust leaks or unusual noises indicating turbo wear.

3. **Engine and Drivetrain Health**

- **Compression Test:** Ensure the engine is healthy; low compression can indicate internal damage.

- **Transmission Check:** Test shifting smoothness and listen for grinding noises.

4. **Body and Interior Condition**

- **Rust:** Check undercarriage, wheel wells, and rocker panels for corrosion (common in older BMWs).

- **Interior Wear:** Leather and plastics degrade over time; assess for cracks or excessive wear.

5. **Cost of Ownership**

- **Insurance:** Get quotes these cars are expensive to insure.

- **Parts Availability:** While parts exist, some OEM components (e.g., specific racks) may require longer lead times.

---

### **Conclusion and Recommendation**

#### **Who Should Buy?**

- **Enthusiasts who prioritize driving dynamics and luxury** and are prepared for high maintenance costs.

- **Owners who can afford regular servicing** (oil changes, transmission fluid, turbo inspections).

- **Buyers who find a well-documented example** with a **recently replaced or converted power steering rack**, minimal rust, and a clean maintenance history.

- **Those who enjoy the challenge of owning a high-performance luxury car** and are not deterred by potential repair bills.

#### **Who Should Avoid?**

- **Budget-conscious buyers** these cars are expensive to own long-term.

- **Those unwilling to invest in maintenance** neglect leads to costly failures.

- **Daily drivers** fuel economy, repair frequency, and insurance costs make them impractical for everyday use.

- **Buyers who cannot verify the power steering rack s condition** this is the single biggest reliability risk.

#### **Final Recommendation**

If you **absolutely love the E65/E66 platform** and can afford the upkeep, **buy with caution**:

1. **Prioritize models with a documented power steering rack replacement or electric conversion**.

2. **Get a pre-purchase inspection** focusing on the rack, engine, transmission, and suspension.

3. **Budget for at least $2,000 $3,000 annually** for maintenance and potential repairs.

4. **Consider a lower-mileage example (under 80,000 miles)** if possible, as the V12/V8 engines are more reliable in this range.

**Alternative Consideration:**

If the power steering issue is a dealbreaker, explore **electric power steering conversions** (e.g., **Steer-By-Wire**) or look for **E63/E64 M5/M6 models**, which share some components but have slightly different reliability profiles. However, no BMW of this era is without trade-offs owning one of these cars is as much about passion as it is about practicality.

For most buyers, the **E65/E66 is a fantastic car for those who can afford its demands**, but it is not a "set-and-forget" luxury sedan. Treat it like a high-performance machine that requires diligent care.
