### **Pros and Cons of Buying a Ford 2355R (2015 2018) or Lincoln MKX (2016 2018) with Rack-and-Pinion Steering**
#### **Pros**
**1. Reliability and Durability**
- The **Ford 2355R** (used in the 2015 2018 Ford Edge and 2016 2018 Lincoln MKX) is a well-regarded V6 engine (3.5L EcoBoost) known for its robustness when maintained properly. It is less prone to catastrophic failure compared to some older engines, especially if the owner followed service intervals.
- The **rack-and-pinion steering** system is generally more durable than recirculating ball steering, offering smoother operation and fewer binding issues over time. It also tends to last longer if not abused.
**2. Good Fuel Economy for a V6**
- The **3.5L EcoBoost** provides a balance between power and efficiency, delivering around **20 22 MPG combined** in the Edge/MKX, which is decent for a V6 SUV of its era. This is better than many naturally aspirated V6s from competitors.
**3. Strong Resale Value**
- Both the **Ford Edge** and **Lincoln MKX** hold their value relatively well compared to some luxury SUVs. The **MKX** (especially the 2016 2018 models) is particularly well-regarded for its refinement and comfort, which can make it easier to resell later.
**4. Comfortable Ride and Interior Quality**
- The **MKX** (Lincoln s take on the Edge platform) offers a more premium interior with better materials, quieter cabin, and refined ride quality. The **Edge** is still a solid choice but lacks some of the luxury touches.
- Both models come with **all-wheel drive (AWD)** as an option, which is useful for light off-road or winter driving.
**5. Availability of Parts and Mechanics**
- Ford and Lincoln parts are widely available, and mechanics familiar with these models are common. The **3.5L EcoBoost** is a popular engine, so finding help for maintenance or repairs is easier than with niche vehicles.
**6. Tech Features (Especially in Later Models)**
- The **2016 2018 models** come with **SYNC 3** (in some trims), which is a more advanced infotainment system compared to earlier generations. Bluetooth, USB ports, and basic navigation are standard in higher trims.
- The **MKX** often includes **adaptive cruise control** and **lane-keeping assist** in higher trims, which are useful safety features.
**7. Decent Towing Capacity**
- The **3.5L EcoBoost** can tow up to **5,000 lbs** when properly equipped, making these SUVs suitable for light towing needs (trailers, small boats, etc.).

#### **Cons**
**1. Turbocharger and Oil Consumption Issues**
- The **3.5L EcoBoost** is turbocharged, which means it is more prone to **oil consumption** than naturally aspirated engines. Some owners report **burning oil** (especially in higher-mileage examples), which can lead to **smoke from the exhaust** and potential engine damage if ignored.
- **Solution:** Check oil levels frequently and consider using **synthetic oil** (preferably **5W-30 or 5W-40**). If oil consumption is excessive, a **turbo upgrade or oil injection system** may be needed.
**2. Transmission Problems (Especially in Early 2015 Models)**
- The **6-speed automatic transmission** in the **2015 Edge** has had some reports of **rough shifting, delayed engagement, or failure** in severe cases. The **2016 2018 models** improved slightly, but some still experience **jerky shifts under load**.
- **Solution:** Ensure the transmission fluid is changed **every 60,000 100,000 miles** (Ford recommends 60K). If shifting is rough, a **transmission flush or rebuild** may be necessary.
**3. Suspension Wear and Noise**
- Both the **Edge and MKX** can develop **worn suspension components** (struts, bushings, control arms) over time, leading to **clunking noises over bumps** or a **harsher ride**.
- **Solution:** Inspect suspension parts every **50,000 70,000 miles** and replace worn components.
**4. Electrical Gremlins (Especially in Lincoln MKX)**
- The **MKX** has had some reports of **intermittent electrical issues**, such as:- **SYNC system freezing or rebooting**
- **Power window or door lock malfunctions**
- **Sensor failures (e.g., rain sensor, parking sensors)**
- **Solution:** These are often software-related and may require **SYNC updates** or **sensor recalibration**. Avoid extreme weather exposure to electronics.
**5. Infotainment Lag and Glitches**
- The **SYNC system** (especially in earlier 2015 models) can be **slow to respond** and may **freeze occasionally**. Later models (2016 2018) are improved but still not as smooth as modern systems.
- **Solution:** Keep the system updated via **Ford s SYNC app** or a dealership.
**6. Higher Maintenance Costs Than Compact SUVs**
- While not as expensive as luxury brands, **Ford/Lincoln parts and labor** can be **more costly** than Japanese or Korean SUVs. The **EcoBoost engine** also requires **more frequent oil changes** than a naturally aspirated V6.
**7. Potential Rust Issues (Especially in Snow-Belt Regions)**
- If the vehicle was driven in **snowy or salted roads**, check for **rust in wheel wells, undercarriage, and frame rails**. Rust can weaken structural components over time.
- **Solution:** Inspect thoroughly before purchase and address any rust immediately.
**8. Limited Off-Road Capability**
- While the **AWD system works well for light off-roading**, these SUVs are **not true off-roaders**. They lack **locking differentials, high ground clearance, or skid plates**, so they are best suited for **paved roads and light trails**.
