Critical 2016 ford explorer problems Every Owner Should Know
When discussing 2016 ford explorer problems, the conversation usually starts with the Electric Power Assisted Steering (EPAS). This system is known to fail without warning, making the vehicle extremely difficult to steer at low speeds.
If you experience a “Steering Assist Fault” message on your dash, it is a sign that the steering rack or the electronic motor is failing. For many DIYers, replacing the entire rack is a significant task that requires a subframe drop and specialized alignment tools afterward.
Another major concern is the internal water pump found in the 3.5L Cyclone V6 engine. Unlike traditional pumps, this one is driven by the timing chain and sits inside the engine block. If it leaks, coolant mixes with the oil, which can lead to catastrophic engine failure if not caught immediately.
Power Steering Rack Failure Symptoms
One of the first signs of steering trouble is a heavy or “notchy” feeling when turning the wheel. You might also hear a whining or grinding noise coming from the front end during low-speed maneuvers, such as parking.
Check your battery voltage first, as low power can sometimes trigger false steering codes. If the battery is healthy, use an OBD-II scanner to check for codes like P0633 or U3000, which point directly to the steering control module.
The Internal Water Pump “Ticking Time Bomb”
Because the water pump is hidden, you must look for indirect signs of failure. Check your oil dipstick regularly for a milky, “chocolate milk” appearance, which indicates coolant contamination.
If you notice a sweet smell or see coolant dripping from the weep hole behind the alternator, the pump’s internal seals have likely failed. Replacing this pump is a 10-12 hour job that involves removing the timing cover and timing chain, so many owners choose to hire a professional for this specific repair.
Addressing Transmission Shifting and Durability Issues
The 6F50 and 6F55 transmissions used in this model year are generally robust but are not without their faults. Many owners report harsh shifting or a noticeable shudder when the torque converter engages between 30 and 50 mph.
Regular maintenance is the best defense against these 2016 ford explorer problems. Ford suggests long intervals for transmission fluid, but experienced mechanics recommend a drain and fill every 30,000 to 50,000 miles to remove metal shavings and degraded fluid.
If you notice a delay when shifting from Park to Drive, it may be a sign of a failing solenoid pack or a worn-out valve body. Addressing these issues early can prevent the need for a full transmission rebuild later on.
DIY Transmission Fluid Service
To perform a fluid service, you will need a low-profile drain pan and about 5-6 quarts of Mercon LV fluid. Ensure the vehicle is level when checking the fluid via the small dipstick located deep in the engine bay.
Avoid “flushing” machines, as they can dislodge debris that clogs small passages. A simple drain and fill is much safer for high-mileage transmissions that have not been serviced regularly.
Torque Converter Shudder Fixes
If you feel a vibration similar to driving over rumble strips, try adding a friction modifier designed for Ford transmissions. While this is often a temporary fix, it can help diagnose if the issue is internal wear or simply fluid breakdown.
If the shudder persists, the torque converter likely needs replacement. This requires pulling the transmission, which is a heavy-duty DIY task that requires a transmission jack and plenty of floor space.
Exhaust Fumes and Carbon Monoxide Safety Concerns
A widely reported issue with this generation of Explorer is the smell of exhaust fumes inside the cabin, particularly during heavy acceleration. This is often caused by cracked exhaust manifolds or unsealed body seams at the rear of the vehicle.
This is a significant safety hazard as it can lead to carbon monoxide poisoning. Ford issued several technical service bulletins (TSBs) to address this, which involve reprogramming the HVAC system and sealing the rear air extractors.
If you smell sulfur or “rotten eggs” while driving, check the exhaust manifold bolts. These bolts are notorious for snapping off, which allows exhaust gases to escape directly into the engine bay and eventually the cabin.
Inspecting the Rear Air Extractors
The rear air extractors are located behind the rear bumper cover. Over time, the rubber flaps can get stuck open or perish, allowing exhaust to be sucked back into the cabin through the negative pressure created while driving.
You can inspect these by removing the interior trim panels in the cargo area. If you see daylight or dirt build-up around the vents, they need to be replaced or resealed with automotive-grade silicone.
Replacing Cracked Exhaust Manifolds
The 3.5L EcoBoost engines are especially prone to manifold warping. If you hear a loud ticking noise when the engine is cold that disappears once it warms up, you likely have a manifold leak.
Replacing these manifolds is a tedious job due to the tight space. Use stainless steel studs and high-quality gaskets to ensure the repair lasts longer than the factory components.
Electrical Gremlins and SYNC Infotainment Glitches
Modern vehicles rely heavily on software, and diagnosing 2016 ford explorer problems often involves the SYNC 2 or SYNC 3 infotainment system. Common complaints include frozen screens, GPS inaccuracies, and Bluetooth connectivity issues.
Before assuming the hardware is bad, try a master reset through the settings menu. If that fails, you can often fix software bugs by downloading the latest firmware from the Ford website onto a USB drive and performing a manual update.
Another common electrical issue is the rearview camera failing. The image may become distorted, inverted, or show a black screen. This is usually caused by a faulty camera module or a pinched wire in the liftgate harness.
Troubleshooting the Backup Camera
Open the liftgate and inspect the wiring harness near the hinge. Repeated opening and closing can fray the wires over time. If the wires are intact, the camera module itself is likely the culprit.
Replacing the camera involves removing the exterior trim panel (the “Explorer” branded piece) on the liftgate. It is a straightforward DIY job that only requires basic hand tools and a plastic trim removal kit.
Addressing Battery Drain Issues
If your Explorer has a dead battery after sitting overnight, you may have a parasitic draw. A common culprit is the “Park” sensor in the shifter assembly, which fails to tell the computer the car is off, keeping the modules awake.
Use a multimeter to perform a parasitic draw test at the fuse box. If you find a high milliamp draw while the car is off, pull fuses one by one until the draw drops to identify the offending circuit.
Suspension and Chassis Maintenance for Off-Roaders
While the Explorer is a unibody SUV, many owners use it for light off-roading or towing. This puts extra stress on the rear suspension toe links, which have been the subject of multiple recalls due to their tendency to snap.
Preventing 2016 ford explorer problems during trail rides starts with a thorough inspection of the bushings and links. If you hear a clunking noise over bumps, your sway bar links or strut mounts are likely worn out.
For those who frequently drive on washboard roads, upgrading to heavy-duty struts can significantly improve ride quality and prevent the premature failure of other suspension components.
Replacing Rear Toe Links
Because of the safety risk, you should check if your vehicle has an open recall for the rear toe links. If not, and you see signs of rust or cracking on the links, replace them immediately.
You will need a torque wrench to ensure the new links are tightened to the correct specification. Always perform a four-wheel alignment after any suspension work to prevent uneven tire wear.
Upgrading for Off-Road Use
If you take your Explorer off the pavement, consider installing skid plates to protect the low-hanging oil pan and transmission. The factory plastic splash guards offer very little protection against rocks or debris.
Additionally, check your PTU (Power Transfer Unit) fluid if you have an Intelligent 4WD model. The PTU holds a very small amount of oil that gets extremely hot; changing this fluid every 30,000 miles is vital for off-road reliability.
Frequently Asked Questions About 2016 ford explorer problems
How can I tell if my 2016 Ford Explorer has a water pump leak?
Look for a drop in the coolant reservoir level without any visible external leaks. You should also check the oil for a milky appearance and listen for a rattling noise from the timing chain area, which can indicate the pump bearing is failing.
Is there a recall for the steering issues on the 2016 Explorer?
There have been various recalls and extended warranties for the EPAS system depending on the specific build date and VIN. Check the NHTSA website with your VIN to see if your vehicle is covered for a free steering rack replacement.
Why does my Explorer smell like gas or exhaust inside?
This is usually due to cracked exhaust manifolds or failing seals in the rear cargo area. It is a known issue that requires sealing the body and inspecting the exhaust system for leaks to prevent carbon monoxide entry.
What is the most reliable engine for the 2016 model year?
The 2.3L EcoBoost four-cylinder is often considered slightly more reliable regarding maintenance because it uses an external water pump. However, the 3.5L V6 is very durable as long as the internal water pump is replaced proactively.
How often should I change the PTU fluid?
Although Ford often labels it as “lifetime” fluid, most experts recommend changing the PTU fluid every 30,000 miles, especially if you tow or drive in hot climates, to prevent the fluid from turning into “sludge.”
