Understanding the 2017 ford explorer xlt reliability and Common Mechanical Issues
The 2017 model year falls within the fifth generation of the Explorer, which benefited from several years of refinements. However, “reliability” is a broad term that depends heavily on which powertrain is sitting under your hood. The XLT trim typically comes with either the 3.5L Ti-VCT V6 or the 2.3L EcoBoost four-cylinder engine.
The 3.5L Cyclone V6 is a workhorse, but it has one major “Achilles heel” that every owner must know about. The water pump is driven by the timing chain and is located inside the engine block. If it fails, it can leak coolant directly into the oil pan, potentially destroying the engine.
On the other hand, the 2.3L EcoBoost offers better fuel economy and avoids the internal water pump design. However, being a direct-injection turbo engine, it is more susceptible to carbon buildup on the intake valves. Knowing these distinctions is the first step in mastering 2017 ford explorer xlt reliability for your specific vehicle.
The Internal Water Pump Challenge
If you have the 3.5L V6, you must monitor your coolant levels religiously. A disappearing coolant reservoir with no visible puddles on the ground is a massive red flag. This often means the internal pump is weeping into the crankcase.
Check your oil dipstick for a “milky” or “chocolate milk” appearance. If you see this, do not start the engine, as coolant destroys the lubricating properties of the oil. Replacing this pump is a labor-intensive job that involves removing the timing cover and chain.
EcoBoost Carbon Buildup
The 2.3L EcoBoost engine is generally reliable but can suffer from “stuttering” or loss of power over time. This is often caused by carbon deposits on the intake valves because fuel doesn’t wash over them in a direct-injection system. Using high-quality synthetic oil and regular Italian tune-ups (spirited driving) can help minimize this.
The PTU and Drivetrain: Avoiding the “Lifetime Fluid” Trap
One of the biggest hurdles to 2017 ford explorer xlt reliability is the Power Transfer Unit (PTU) found in All-Wheel Drive (AWD) models. The PTU is responsible for sending power to the rear wheels. Ford originally marketed the PTU fluid as “filled for life,” but enthusiasts and mechanics disagree.
The PTU sits very close to the exhaust manifold, which subjects the small amount of gear oil inside to extreme heat. Over time, this oil turns into a thick, sludge-like consistency often compared to “burnt molasses.” If the fluid breaks down completely, the PTU gears will grind and fail.
To prevent a costly $1,500 to $2,000 replacement, we recommend changing the PTU fluid every 30,000 miles. This is a messy job for a DIYer because many units lack a drain plug, requiring the fluid to be sucked out through the fill hole. However, it is the single best way to ensure your drivetrain stays healthy.
Signs of PTU Failure
Listen for a high-pitched whining noise that increases with vehicle speed. You might also notice a distinct “propane-like” or burnt oil smell after a long drive. If you see silver metallic flakes in the fluid during a change, the internal bearings are already starting to go.
Transmission Health (6F50/6F55)
The 6-speed automatic transmission in the 2017 Explorer is generally robust if maintained. Some owners report “harsh shifts” or hesitation between gears. Often, a simple drain and fill of the transmission fluid (using Mercon V) can resolve these minor software or pressure issues.
Suspension and Steering: The Rear Toe Link Issue
If you notice your Explorer feels “loose” in the rear or makes a clunking sound over bumps, check the toe links. The 2017 Ford Explorer has been subject to recalls regarding rear suspension toe links that can fracture. This is a critical safety item because a fracture can lead to a loss of steering control.
Inspect the rear suspension for any visible cracks or excessive play in the bushings. Even if your vehicle has had the recall performed, these parts endure a lot of stress, especially if you tow or go off-road. High-quality aftermarket replacements with greaseable fittings are a popular upgrade for DIYers.
Wheel bearings are another common wear item on this platform. If you hear a “humming” or “growling” noise that changes pitch when you turn the steering wheel, a hub assembly is likely failing. Replacing a front hub assembly is a straightforward task for a weekend mechanic with a good torque wrench.
Interior Electronics and the Sync 3 System
The 2017 model was a great year for tech because it featured the Sync 3 infotainment system. Unlike the previous “MyFord Touch,” Sync 3 is much faster and supports Apple CarPlay and Android Auto. This significantly boosts the perceived 2017 ford explorer xlt reliability because the interface is less prone to crashing.
However, some owners experience issues with the GPS antenna or the APIM (Accessory Protocol Interface Module). If your screen goes black or the navigation becomes “lost,” a master reset is the first step. If that fails, you may need to replace the APIM, which is located behind the screen.
Another interior quirk involves the climate control. If you hear a clicking sound behind the dashboard when changing the temperature, a blend door actuator has likely failed. These are small plastic motors that are inexpensive to buy but can be a bit of a “knuckle-buster” to install depending on which one broke.
Backup Camera Glitches
A common complaint involves the backup camera showing a blue screen or a distorted image. This is usually caused by a failing camera module in the liftgate or a loose wiring harness. Before buying a new camera, check the connection inside the rear hatch panel for corrosion or moisture.
The “Exhaust Smell” and Cabin Safety
A specific concern regarding 2017 ford explorer xlt reliability involves reports of exhaust fumes entering the cabin. This typically occurs under heavy acceleration. While Ford has issued various technical service bulletins (TSBs) to address this, it remains a point of concern for many owners.
The issue often stems from unsealed seams in the rear of the vehicle or cracked exhaust manifolds. If you smell fumes, inspect the exhaust manifolds for soot or cracks, especially on the 3.5L engines. Replacing the cabin air filter with a high-quality carbon-activated version can help, but it won’t fix a mechanical leak.
For your safety, consider carrying a portable carbon monoxide detector if you suspect a leak. Ensure the rear liftgate seals are clean and pliable. Any gap in the weatherstripping can allow exhaust “vortexing” to pull gases back into the cabin while driving at highway speeds.
Essential Maintenance Schedule for the DIY Mechanic
To maximize the life of your Explorer, you should move beyond the “standard” dealership intervals. Modern SUVs work hard, and heat is the primary enemy of mechanical longevity. Follow this “enthusiast” schedule to keep your XLT in top shape.
- Engine Oil: Change every 5,000 miles using full synthetic oil. This is vital for the 2.3L EcoBoost turbo and the 3.5L timing chain.
- Coolant: Flush every 60,000 miles. Fresh coolant prevents the internal water pump seals from hardening and leaking.
- PTU Fluid: Change every 30,000 miles. Do not believe the “lifetime” claim.
- Transmission Fluid: Perform a drain and fill every 50,000 miles. Avoid high-pressure flushes which can dislodge debris.
- Spark Plugs: Replace every 60,000 miles, especially on EcoBoost models, to prevent ignition coils from overworking.
Tools You Will Need
If you plan on maintaining your Explorer yourself, a few specific tools will make life easier. A fluid extraction pump is mandatory for the PTU and differential service. You will also want a set of metric sockets, a 1/2-inch drive torque wrench, and a scan tool capable of reading Ford-specific codes (like FORScan).
Having a solid floor jack and high-quality jack stands is non-negotiable. The Explorer is a heavy vehicle, and you should never work under it supported only by a hydraulic jack. Always chock the wheels and use secondary safety measures when performing suspension or brake work.
Frequently Asked Questions About 2017 ford explorer xlt reliability
Is the 2017 Ford Explorer XLT a good used car?
Yes, it is generally a strong performer. However, its long-term value depends on whether the previous owner addressed the PTU fluid and monitored the water pump. It offers great utility and modern tech for the price point.
How long will a 2017 Ford Explorer last?
With meticulous maintenance, these vehicles can easily cross the 200,000-mile mark. The engines and transmissions are physically stout; the failures usually come from neglected fluids or the specific internal water pump issue on the V6.
