This guide breaks down the most critical reliability concerns, from steering failures to internal engine leaks, providing actionable solutions to keep your SUV on the road.

Owning a fifth-generation SUV is a great way to handle family duties and weekend adventures, but it can be frustrating when mystery noises or warning lights appear. You deserve a vehicle that is as reliable as it is capable, whether you are commuting or heading to a remote campsite. In this guide, I will detail the most common problems with ford explorer 2011 owners face and how you can address them effectively.

We will explore the infamous power steering failures, the “hidden” water pump issues in the 3.5L engine, and the nuances of the Power Transfer Unit. By the end of this article, you will have a clear roadmap for diagnosing and repairing these specific 2011 model year quirks. Let’s dive into the technical details and get your Explorer back in peak condition.

Understanding the Steering System problems with ford explorer 2011 Models

One of the most frequent complaints regarding this model year involves the Electric Power Assisted Steering (EPAS) system. Unlike older hydraulic systems, this setup uses an electric motor to provide assistance, which can fail without much warning. When it fails, the steering becomes incredibly heavy, making the vehicle difficult to maneuver at low speeds.

Ford issued recalls for many units, but not every vehicle was covered under the initial campaigns. If you see a “Service Power Steering Now” message on your dashboard, do not ignore it. This often indicates a fault in the steering rack’s internal sensors or a software glitch that requires a professional scan tool to reset.

Diagnosing EPAS Failure

Start by checking the battery voltage, as electric steering is highly sensitive to power fluctuations. A weak battery or a failing alternator can trigger steering fault codes even if the rack itself is healthy. Use a multimeter to ensure you have at least 12.6 volts with the engine off and 14 volts while running.

If the battery is fine, inspect the electrical connectors leading to the steering rack for corrosion or loose pins. Off-roaders should be especially careful, as mud and water can ingress into these sensitive connections. If the internal motor has failed, the entire steering rack usually needs replacement, which is a significant job for a weekend DIYer.

The Recall 14S06 and Software Updates

Check your VIN on the Ford owner portal to see if recall 14S06 has been performed on your vehicle. This recall involved updating the Power Steering Control Module (PSCM) software to prevent a total loss of steering assist. Even if your car isn’t recalled, a dealership can often perform a software flash that resolves intermittent “stiff” spots in the steering wheel.

Engine Reliability: The 3.5L V6 Water Pump Challenge

The 3.5L Ti-VCT Cyclone V6 is a powerhouse, but it features a design choice that keeps many mechanics up at night. The water pump is driven by the timing chain and is located inside the engine front cover. When this pump fails, it doesn’t just leak on the ground; it often leaks directly into the oil pan.

Mixing coolant with engine oil creates a “chocolate milkshake” consistency that destroys rod bearings and cam journals rapidly. This is a critical failure point that requires immediate attention if you notice your coolant level dropping without any visible external leaks. Monitoring your oil color is a mandatory habit for 2011 Explorer owners.

The “Weep Hole” Inspection

Ford engineers did include a weep hole designed to vent leaking coolant outside the engine block before it enters the oil. You can find this hole behind the alternator on the side of the engine block. Use a small mirror and a flashlight to check for any crusty orange or green residue around this area during every oil change.

If you see signs of leakage, you must replace the pump immediately. This job involves removing the intake manifold, the valve covers, and the front timing cover. It is a labor-intensive process that usually takes 10 to 12 hours, so many owners choose to replace the timing chain and tensioners at the same time.

Preventative Maintenance for the Cooling System

To extend the life of your internal water pump, never skip a coolant flush. Old coolant becomes acidic and eats away at the pump’s internal seals. Use only Motorcraft Orange or the newer Yellow approved coolant, and avoid mixing universal brands that might not have the correct additives for Ford’s seals.

Drivetrain and PTU Issues: Keeping the AWD System Alive

If your 2011 Explorer is equipped with Intelligent 4WD, you have a Power Transfer Unit (PTU) bolted to the transmission. This unit sends power to the rear wheels, but it is notorious for overheating. Ford originally claimed the fluid was “lifetime,” but real-world experience proves otherwise, especially for those who tow or drive off-road.

The PTU holds a very small amount of gear oil (usually less than a quart) and sits very close to the hot exhaust manifold. Over time, the oil turns into a thick, black sludge that resembles molasses. Once the oil breaks down, the internal bearings fail, leading to a costly replacement of the entire unit.

Signs of PTU Distress

Listen for a high-pitched whine or a grinding noise that changes with vehicle speed. You might also smell a “propane-like” or burnt oil odor after a long highway drive. If you see oil leaking from the PTU seals, the internal pressure from cooked oil has likely blown the gaskets.

I recommend changing the PTU fluid every 30,000 miles, even though the manual doesn’t require it. Since many 2011 units do not have a drain plug, you will need to use a suction pump to extract the old oil through the fill plug. Refill it with a high-quality 75W-140 full synthetic gear lubricant.

Optimizing the Terrain Management System

The 2011 Explorer features a dial to select different driving modes like Sand, Mud/Ruts, and Grass/Gravel/Snow. While effective, using these modes on dry pavement can strain the PTU and center differential. Only engage these modes when the surface allows for tire slip to prevent “driveline wind-up,” which can accelerate mechanical wear.

Interior Electronics and MyFord Touch Glitches

The 2011 model year was the debut for the MyFord Touch infotainment system, and it was plagued with software bugs. Common issues include the screen freezing, the backup camera not displaying, or the Bluetooth failing to sync. While frustrating, most of these are software-related rather than hardware failures.

If your screen is unresponsive, you can often perform a “Master Reset” in the settings menu. If that doesn’t work, pulling the fuse for the Sync system (usually located in the passenger footwell) for 60 seconds can force a hard reboot. Keeping the system updated to the latest available software version is the best way to minimize these headaches.

The Rear Liftgate Crack

A purely aesthetic but very common issue is the plastic panel just below the rear window on the liftgate. It frequently develops a vertical crack, often right through the Ford logo. This is caused by the plastic expanding and contracting at a different rate than the metal liftgate it is bolted to.

While this doesn’t affect drivability, it can allow moisture to seep into the liftgate latch mechanism. Some owners choose to replace the panel with a reinforced aftermarket version. If you are a DIYer, you can remove the interior trim of the liftgate to access the nuts holding this panel in place for a relatively simple replacement.

Suspension and Braking System Wear

Because the 2011 Explorer is a heavy vehicle, it puts significant stress on its suspension components. Owners often report clunking noises when going over bumps or a “loose” feeling in the steering. This is frequently traced back to worn lower control arm bushings or stabilizer bar links.

Inspect your front tires for uneven wear patterns. If the inside edge is wearing faster than the rest of the tire, your control arm bushings are likely shot, causing the alignment to shift under load. Replacing the entire control arm is often easier for a DIYer than trying to press out the old bushings.

Brake Pulsation and Rotor Warping

The factory brake rotors on the 2011 model are prone to warping if subjected to heavy braking or mountain descents. If you feel a vibration in the brake pedal, it is time for new rotors. When replacing them, I suggest upgrading to “heavy-duty” or “towing” grade vented rotors to help dissipate heat more effectively.

Always clean the hub surface thoroughly before installing new rotors. Even a tiny bit of rust between the hub and the rotor can cause “run-out,” which leads to the vibration returning within a few thousand miles. Use a wire brush and a bit of brake cleaner to ensure a perfectly flat mating surface.

Frequently Asked Questions About problems with ford explorer 2011

Is the 2011 Ford Explorer a reliable used car purchase?

The 2011 model is generally reliable if the major items like the water pump and PTU have been maintained. However, because it was the first year of a new generation, it has more “teething” issues than the 2013-2015 models. Always check the service history for coolant changes and steering rack replacements.

How do I know if my water pump is failing?

Look for a disappearing coolant reservoir without puddles under the car. Check the oil dipstick for a milky appearance. You can also look for leaks near the alternator area, which indicates the pump’s internal seals are starting to give way.

Can I fix the power steering myself?

Basic electrical checks and software resets are DIY-friendly. However, replacing the steering rack requires dropping the subframe and performing a specialized alignment. This is usually considered an advanced DIY project or a job for a professional shop.

Why does my Explorer smell like burnt oil?

This is often the PTU fluid overheating and venting through the top of the unit. It can also be caused by oil leaking from the valve cover gaskets onto the hot exhaust manifolds. Inspect the PTU for leaks and check the rear of the engine for oil dampness.

What is the average lifespan of a 2011 Ford Explorer?

With meticulous maintenance, these vehicles can easily reach 200,000 miles. The engine and transmission are robust, but the peripheral systems like the cooling and AWD components require proactive care to reach those high mileage milestones.
