Let’s dive into the details and see how this Ford stacks up against the competition.
The Core Components of 2018 Ford Explorer XLT Reliability
When assessing 2018 ford explorer xlt reliability, you have to look at the foundation of the vehicle. The 2018 model year falls toward the end of the fifth generation (U502), meaning Ford had several years to work out the initial “bugs” found in earlier versions. For the XLT trim, you are typically looking at two main engine choices and a robust, though sometimes quirky, drivetrain.
The XLT serves as the “sweet spot” for many buyers, offering a mix of cloth or leather seating and essential tech without the price tag of the Limited or Platinum trims. From a reliability standpoint, the simpler electronics in the XLT can actually be a benefit. Fewer motorized gadgets often mean fewer small components that can fail over a decade of use.
However, the mechanical heart of the vehicle is where you should focus your attention. Most XLT models come equipped with the 3.5L Ti-VCT V6 or the 2.3L EcoBoost four-cylinder. Both engines have distinct maintenance requirements that directly impact how many miles you can squeeze out of the odometer. Let’s look at how these powertrains behave in the real world.
The 3.5L Cyclone V6: A Proven Workhorse with a Catch
The naturally aspirated 3.5L V6 is the most common engine found in the XLT trim. It is known for smooth power delivery and a relatively simple design compared to its turbocharged siblings. For many owners, this engine is the gold standard for 2018 ford explorer xlt reliability because it lacks the complexity of a turbocharger system.
However, there is a significant “pro tip” every owner should know: the water pump. In this specific engine design, the water pump is located behind the timing cover and is driven by the timing chain. If the pump seal fails, it can leak coolant directly into the engine oil, which can lead to catastrophic engine failure if not caught immediately.
To mitigate this risk, always monitor your coolant levels and look for a “milky” appearance on the oil dipstick. If you notice the coolant reservoir dropping without a visible external leak, have a professional pressure test the system. Replacing the pump is a labor-intensive job, but it is far cheaper than replacing the entire long-block engine.
The 2.3L EcoBoost: Efficiency Meets Complexity
The 2.3L EcoBoost engine offers better fuel economy and surprising torque for a four-cylinder. It is a great option for those who do a lot of highway cruising or light-duty commuting. While generally reliable, turbocharged engines run hotter and put more stress on the engine oil and cooling system.
One common issue with Gasoline Direct Injection (GDI) engines like the EcoBoost is carbon buildup on the intake valves. Because fuel is sprayed directly into the cylinder, it doesn’t “wash” the back of the valves. Over time, this can lead to a rough idle or reduced power. Using high-quality synthetic oil and performing an intake cleaning every 50,000 miles can help maintain efficiency.
Additionally, keep an eye on the turbocharger heat shields and vacuum lines. Heat is the enemy of plastic and rubber components. If you live in a hot climate or frequently tow small trailers, ensure you are following the “severe duty” maintenance schedule found in your owner’s manual to preserve the turbo’s lifespan.
Transmission and Drivetrain: The 6F50 Experience
The 2018 Explorer XLT utilizes the 6-speed SelectShift automatic transmission. For the most part, this transmission is a solid performer, but it does require regular fluid exchanges to stay healthy. Many owners find that 2018 ford explorer xlt reliability is significantly improved by ignoring the “lifetime fluid” claims and sticking to a 30,000 to 45,000-mile service interval.
If you experience “harsh shifts” or a slight hesitation when accelerating from a stop, it might be time for a fluid refresh. Always use the Ford-recommended Mercon LV fluid. Using the wrong fluid type can lead to torque converter shudder or internal clutch wear, which are expensive fixes that no DIYer wants to tackle on a Saturday afternoon.
For those with the Intelligent 4WD system, the Power Transfer Unit (PTU) is another critical area. The PTU is responsible for sending power to the rear wheels. Because it sits close to the exhaust, the gear oil inside can “cook” and turn into a thick sludge. Changing this fluid is a bit tricky but essential for anyone planning on taking their Explorer off the pavement.
Managing the Power Transfer Unit (PTU)
The PTU is often the weak link in the Explorer’s AWD system. Because it only holds about 18 ounces of 75W-140 gear oil, it doesn’t take much heat to degrade the lubricant. If you smell a “burnt propane” odor after a long drive, your PTU fluid might be failing. This is a common sign that the internal seals are under stress.
Many experienced mechanics recommend installing a drain plug if your unit doesn’t have one, or using a vacuum extraction pump to suck out the old fluid through the fill hole. Doing this every 30,000 miles can prevent a complete PTU failure, which often costs upwards of $1,500 to $2,000 to replace. It is a classic example of how proactive maintenance boosts 2018 ford explorer xlt reliability.
If you are a weekend warrior who hits the trails, the PTU is even more vulnerable. Excessive wheel slip in mud or sand generates significant heat. If you’ve spent a day exploring forest service roads, it’s a good practice to crawl under the vehicle and check for any leaks around the PTU seals or the intermediate shaft.
Suspension and Chassis: Staying Level on the Road
The Explorer is a heavy vehicle, and that weight puts a lot of stress on the suspension components. One of the most frequent complaints regarding the 2018 model involves the rear suspension, specifically the toe links. Ford has issued recalls for these parts in the past because they can fracture, leading to a loss of steering control.
When driving, listen for any clunking or rattling sounds coming from the rear end, especially when going over speed bumps or uneven terrain. If the steering feels “loose” or the vehicle wanders in its lane, have the rear toe links and bushings inspected immediately. This is a critical safety item that directly impacts your confidence behind the wheel.
Front-end components like strut mounts and lower control arm bushings also tend to wear out around the 80,000-mile mark. If you notice uneven tire wear or a “pull” to one side, it is likely time for a suspension refresh. For the DIY mechanic, replacing these parts is straightforward with a good set of jack stands and a torque wrench.
Braking System and Tire Maintenance
Brake wear on the 2018 Explorer is fairly standard for a vehicle of its size. However, because it uses an electronic parking brake and various stability control systems, you want to ensure your brake pads are high-quality ceramic or semi-metallic. Cheap pads can lead to excessive dust and annoying squeals that take away from the driving experience.
Tire rotation is equally important, especially on AWD models. Different tread depths between the front and rear axles can put unnecessary strain on the center differential. Aim to rotate your tires every 5,000 to 7,500 miles. This simple step ensures even wear and keeps your traction control system from getting “confused” by varying wheel speeds.
If you plan on light off-roading, consider upgrading to a tire with a slightly more aggressive tread pattern and a higher load rating. The factory tires are optimized for highway fuel economy, but they can be prone to sidewall damage on rocky paths. A set of mild All-Terrain tires can enhance your 2018 ford explorer xlt reliability in the wild.
Electronics and Interior Technology: The Sync 3 System
The 2018 XLT usually comes with the Sync 3 infotainment system, which is a massive improvement over the older MyFord Touch. It is generally stable and supports Apple CarPlay and Android Auto. However, like any computer, it can occasionally freeze or lag. Keeping the software updated via Wi-Fi is the best way to avoid these glitches.
Another electronic area to watch is the backup camera. Some owners have reported the screen going blue or the image becoming distorted. This is often caused by a loose connection or a failing camera module in the liftgate. Before replacing the camera, check the wiring harness for any signs of pinching or corrosion.
The XLT trim also features various sensors for park assist and blind-spot monitoring. These sensors are located in the bumpers and can be sensitive to dirt, mud, or snow. If you get a “sensor blocked” warning, a quick wipe with a microfiber cloth usually solves the problem. It’s a simple fix that prevents unnecessary trips to the dealership.
Climate Control and HVAC Issues
A comfortable cabin is essential for long road trips. The 2018 Explorer uses a dual-zone climate control system that is generally reliable. However, the “blend door actuators” are a known wear item. If you hear a clicking sound behind the dashboard or if one side of the car stays hot while the other is cold, an actuator has likely failed.
Replacing a blend door actuator can be a tedious task depending on which one has failed, as some are buried deep within the dash. If you are a DIYer, there are many forum guides that show how to access them without removing the entire dashboard. Using OEM Ford parts for these actuators is highly recommended to ensure they last another 100,000 miles.
Also, don’t forget to change your cabin air filter annually. A clogged filter puts extra strain on the blower motor and can lead to a musty smell inside the cabin. It is a five-minute job that significantly improves the air quality for you and your passengers, especially during allergy season or dusty trail rides.
Essential Tools for the 2018 Explorer DIYer
If you plan on maintaining your Explorer yourself, having the right tools makes the job much easier. You don’t need a professional shop setup, but a few specific items will go a long way. The 2018 Explorer uses a mix of metric fasteners, so a high-quality socket set is a must-have.
- Digital Torque Wrench: Essential for tightening lug nuts, suspension bolts, and spark plugs to factory specifications.
- OBD-II Scanner: A basic code reader or a Bluetooth dongle with the FORScan app allows you to diagnose “Check Engine” lights and monitor live data.
- Fluid Extraction Pump: Perfect for changing the PTU fluid or removing excess power steering fluid.
- Trim Removal Tools: Plastic pry bars are necessary for accessing the cabin air filter or replacing interior light bulbs without scratching the plastic.
- Heavy-Duty Jack and Stands: Given the Explorer’s weight, ensure your lifting equipment is rated for at least 3 tons for maximum safety.
Having these tools on hand allows you to perform routine checks and minor repairs before they turn into major headaches. Being prepared is the first step in ensuring your 2018 ford explorer xlt reliability remains high throughout your ownership. Plus, doing the work yourself gives you a better understanding of how your vehicle operates.
