2016 Ford Explorer Issues – A Comprehensive Repair And Maintenance
The 2016 Ford Explorer is a versatile SUV, but it is known for specific mechanical vulnerabilities like internal water pump failures and drivetrain PTU overheating. Understanding these common pitfalls allows owners to perform preventative maintenance and avoid the high costs of catastrophic engine or transmission failure.
Owning a 2016 Ford Explorer offers a blend of utility and comfort that few other SUVs in its class can match. Whether you are hauling gear for a weekend camping trip or navigating a snowy commute, this vehicle generally performs with confidence.
However, long-term ownership requires a keen eye for detail to stay ahead of known 2016 ford explorer issues that can arise after the odometer passes the 60,000-mile mark. If you ignore the warning signs, a simple leak or a strange noise can quickly escalate into a multi-thousand-dollar repair bill.
In this guide, we will break down the most critical mechanical concerns, safety recalls, and DIY maintenance steps. By the end of this article, you will have the expert knowledge needed to keep your Explorer running smoothly for another 100,000 miles.
The Internal Water Pump Disaster in the 3.5L Cyclone V6
If your Explorer is equipped with the naturally aspirated 3.5L V6 engine, you must understand the design of its water pump. Unlike most vehicles where the pump is driven by an external accessory belt, this engine uses an internal water pump driven by the timing chain.
This design choice means that when the pump seal fails, it does not just leak on the ground. Instead, the coolant often leaks directly into the engine’s oil pan, creating a milky “sludge” that destroys the engine’s main bearings within miles.
To catch this early, look for a small weep hole located behind the alternator. If you see orange or green crusty deposits near that area, your pump is failing. Replacing this pump is a massive job that requires timing chain removal, so many owners choose to replace the chain and guides at the same time.
Symptoms of Water Pump Failure
- Unexplained loss of coolant without visible puddles under the car.
- A milky, “chocolate milk” appearance on the oil dipstick.
- Sudden engine overheating while idling or driving at low speeds.
Pro Tip for DIYers
If you attempt this repair yourself, you will need a camshaft holding tool to ensure the engine stays in time. Never rotate the crankshaft once the timing chain is removed, or you risk bent valves and total engine loss.
Addressing Common 2016 ford explorer issues with the Drivetrain
For those with Intelligent 4WD models, the Power Transfer Unit (PTU) is a frequent source of frustration. The PTU is a small gearbox that sends power to the rear wheels, and it is positioned very close to the hot exhaust manifold.
Ford originally marketed the PTU fluid as “lifetime,” but many enthusiasts and mechanics have found that the fluid cooks into a thick, black paste. This leads to gear shearing and 2016 ford explorer issues involving total loss of AWD capability or a loud grinding noise from the front end.
To prevent this, you should change the PTU fluid every 30,000 miles, especially if you tow trailers or drive in hilly terrain. Since most 2016 units lack a drain plug, you will need a fluid extraction pump to suck the old oil out through the fill hole.
Signs Your PTU is Failing
- A distinct smell of “burning oil” or “propane” after a long drive.
- A high-pitched whining noise that increases with vehicle speed.
- Fluid leaking from the intermediate shaft seal on the passenger side.
Recommended Lubricants
Always use a high-quality 75W-140 full synthetic gear oil. Some owners even install a custom drain plug or a cooling fin kit to help dissipate the extreme heat generated by the exhaust proximity.
Rear Suspension and the Critical Toe Link Recall
Safety is a priority for any family vehicle, but the 2016 Explorer has faced significant scrutiny regarding its rear suspension. The rear suspension toe links are prone to snapping due to stress corrosion cracking, particularly in regions where road salt is used.
When a toe link breaks, the rear wheel can suddenly turn outward, causing a loss of steering control. This is a dangerous scenario that has led to multiple large-scale recalls by Ford. If you haven’t checked your VIN for open recalls lately, do so immediately.
Symptoms of a failing toe link include a clunking sound over bumps or a “fishtailing” sensation when driving on the highway. If the rear of the car feels loose or disconnected, park the vehicle and inspect the links for cracks.
DIY Inspection Steps
- Jack up the rear of the vehicle and secure it on jack stands.
- Grasp the rear tire at the 3 o’clock and 9 o’clock positions.
- Shake the wheel firmly to check for any play or movement in the linkage.
Electronic Throttle Body and Limp Mode
Many owners have reported a terrifying experience where the vehicle suddenly loses power and enters “Limp Mode.” This is often accompanied by a wrench icon on the dashboard and a complete lack of throttle response.
The culprit is usually a faulty electronic throttle body. The internal gears or the motor inside the housing fail, preventing the butterfly valve from opening correctly. While this is a common entry among 2016 ford explorer issues, it is fortunately one of the easier DIY fixes.
Replacing the throttle body involves removing the air intake duct and four bolts. You can typically complete this job in under 30 minutes with basic hand tools. Always perform a throttle relearn procedure after installation to ensure a steady idle.
Cleaning vs. Replacing
Sometimes, carbon buildup around the butterfly valve causes sticking. You can try cleaning it with a dedicated throttle body cleaner and a soft brush, but if the internal electronics are fried, a total replacement is the only permanent solution.
Turbocharger and Carbon Issues in EcoBoost Models
The 2.3L EcoBoost engine is a punchy, fuel-efficient option, but it brings its own set of challenges. Because it is a Direct Injection (DI) engine, fuel never washes over the back of the intake valves, leading to heavy carbon deposits.
Over time, this carbon buildup causes rough idling, hesitation under acceleration, and reduced fuel economy. To mitigate this, many off-roaders and long-distance drivers install an oil catch can to prevent oil vapors from reaching the intake tract.
Additionally, the turbochargers can develop leaks in the coolant or oil lines. If you see white smoke from the exhaust upon startup, it may indicate a failing turbo seal or a coolant leak within the turbo housing.
Maintenance Tips for EcoBoost Owners
- Use only high-quality, full synthetic oil to prevent turbo “coking.”
- Replace spark plugs every 30,000 to 40,000 miles, as turbos are hard on ignition components.
- Run a Top Tier fuel with high detergency to keep the injectors clean.
Interior Tech and Exterior Cosmetic Problems
Beyond the mechanical oily bits, the 2016 Explorer suffers from a few “quality of life” glitches. The SYNC infotainment system can be laggy or freeze entirely. If your screen goes black, try a master reset through the settings menu or pull the fuse for the APIM module.
On the exterior, the most common complaint is hood paint bubbling. This occurs because the hood is made of aluminum, and iron contaminants during the manufacturing process cause galvanic corrosion under the paint. Once it starts, it is very difficult to stop without replacing the entire hood.
Another common annoyance is the A-pillar trim panels. These plastic strips on the sides of the windshield are held on by fragile clips. At highway speeds, the wind can catch them and rip them off the vehicle, creating a safety hazard for drivers behind you.
Fixing Loose Trim
If you notice your A-pillar trim vibrating, do not wait for it to fly off. You can purchase a replacement clip kit online. Apply a small bead of automotive-grade silicone adhesive to the clips during installation for extra security.
