Ford Explorer Suv Reliability Reviews – The Ultimate Guide To Finding
Searching for a used Ford Explorer requires a keen eye for mechanical detail and a solid understanding of which model years stand the test of time. This guide breaks down the most reliable generations, common mechanical pitfalls like internal water pumps, and essential maintenance steps to keep your SUV on the road or the trail for years to come.
Finding a family vehicle that balances off-road capability with daily comfort is a tall order, but the Ford Explorer has been a staple in this category for decades. If you are currently in the market, you know that searching for ford explorer suv reliability reviews is the first step toward avoiding a “lemon” and finding a powerhouse that lasts.
You want an SUV that can handle a weekend camping trip just as easily as the Monday morning school run. However, not every model year is created equal, and some suffer from expensive flaws that can drain your wallet if you aren’t careful.
In this guide, I will draw on years of mechanical experience to show you exactly what to look for under the hood. We will cover the “Golden Years” of production, the specific engines to avoid, and the DIY checks you can perform right in the seller’s driveway.
Analyzing Ford Explorer SUV Reliability Reviews Across Different Generations
When you start digging into ford explorer suv reliability reviews, you will notice a clear divide between the different design generations. Each era of the Explorer brought new technology, but it also introduced unique mechanical challenges that owners need to understand.
The fifth generation (2011–2019) moved to a car-based unibody platform, which improved handling but changed the maintenance landscape for DIYers. These models are generally sturdy, but they have specific “achilles heels” regarding their cooling systems and Power Transfer Units (PTU) on all-wheel-drive versions.
The sixth generation (2020–Present) returned to a rear-wheel-drive bias, offering better towing and performance. While these newer models offer cutting-edge tech, early production years faced some software glitches and transmission “teething” issues that are well-documented in enthusiast forums.
The Fifth Generation (2011–2019) Strengths
This generation is widely available on the used market and offers a comfortable ride. The 3.5L Ti-VCT V6 engine is a workhorse, often reaching well over 200,000 miles if the oil is changed religiously every 5,000 miles.
However, you must be aware of the internal water pump design on the 3.5L Cyclone engine. Because the pump is driven by the timing chain inside the engine, a leak can dump coolant directly into the oil pan, leading to catastrophic engine failure.
The Sixth Generation (2020–Present) Expectations
The latest Explorer models feature the 10R80 10-speed automatic transmission. Early 2020 models often received Technical Service Bulletins (TSBs) for harsh shifting, which can usually be fixed with a dealership software flash.
If you are looking for performance, the ST trim with the 3.0L EcoBoost engine is a favorite among enthusiasts. Just keep in mind that turbocharged engines require high-quality full synthetic oil to protect the turbo bearings from heat soak.
Common Mechanical Pitfalls: What to Watch Out For
Every vehicle has its quirks, and the Explorer is no exception. Based on my time in the shop, there are three main areas where these SUVs tend to show their age or design flaws.
First is the Electric Power Assist Steering (EPAS) rack. On older fifth-gen models, these units can fail suddenly, making the steering incredibly heavy. If you hear a “whirring” or “crunching” noise when turning the wheel during a test drive, walk away or budget for a pricey replacement.
Second is the PTU fluid in AWD models. Ford originally claimed this fluid was “lifetime,” but many ford explorer suv reliability reviews from owners suggest otherwise. The fluid sits near the exhaust, gets cooked, and turns into a thick sludge, eventually leading to gear failure.
The Internal Water Pump Disaster
As mentioned before, the 3.5L V6 (non-turbo) has a water pump hidden behind the timing cover. To check for a failing pump, look at the weep hole located behind the alternator. If you see orange or green crusty residue there, the pump is dying.
If you buy one of these, I recommend replacing the water pump and timing chain as preventative maintenance around the 120,000-mile mark. It is a labor-intensive job, but it is much cheaper than buying a whole new engine after a coolant-oil mix occurs.
EcoBoost Carbon Buildup
The 2.3L and 3.5L EcoBoost engines use Direct Injection (DI). Because fuel isn’t sprayed over the intake valves, carbon deposits can build up over time, causing rough idles and lost fuel economy.
Using a high-quality intake valve cleaner every 20,000 miles can help mitigate this. For high-mileage units, a professional “walnut blasting” of the intake ports might be necessary to restore original performance levels.
Off-Roading and Suspension Longevity
Many owners use their Explorer for light off-roading or reaching remote trailheads. While the Explorer is capable, its independent rear suspension has several bushings that can wear out prematurely under heavy loads.
Listen for “clunking” sounds when going over speed bumps or uneven terrain. This often indicates that the rear knuckle bushings are shot. Replacing these requires a specialized press tool, so it is a task best suited for an advanced DIYer or a trusted local mechanic.
Upgrading for the Trail
If you plan on frequenting dirt roads, consider upgrading to a set of All-Terrain tires. Not only do they provide better grip, but the thicker sidewalls offer more protection against sharp rocks that could puncture a standard highway tire.
Always check the condition of your CV axles and boots. A torn boot will let dirt into the joint, causing it to click and eventually snap while you are miles away from the nearest paved road.
Essential Maintenance Checklist for Explorer Owners
To ensure your vehicle doesn’t end up as a negative statistic in future ford explorer suv reliability reviews, you must stay ahead of the factory maintenance schedule. Standard “oil and filter” changes are just the beginning.
I suggest a “Severe Service” mindset, especially if you tow or live in a dusty environment. Shorter fluid intervals are the cheapest insurance policy you can buy for a modern, complex SUV.
- Engine Oil: Every 5,000 miles using a high-quality filter.
- PTU Fluid: Every 30,000 miles (extract and refill with 75W-140 gear oil).
- Transmission Fluid: Drain and fill every 50,000 to 60,000 miles.
- Coolant: Flush every 5 years to prevent pH imbalance that eats gaskets.
- Brake Fluid: Test for moisture content every 2 years to protect the ABS module.
Using a basic OBD-II scanner is also a great habit. Even if the “Check Engine” light isn’t on, scanning for “pending codes” can alert you to a misfire or a failing oxygen sensor before it leaves you stranded.
Pro Tips for the Pre-Purchase Inspection (PPI)
Never buy an Explorer without doing your own “boots on the ground” inspection. Even if the car looks shiny, the mechanical health is what determines its true value. Bring a flashlight and a pair of gloves.
Start the engine from a cold soak (meaning it hasn’t been driven for several hours). Listen for a rattling sound that lasts for 2-3 seconds upon startup. This often points to a stretched timing chain or failing cam phasers, which are expensive repairs.
- Check the Oil Cap: Look for “milky” residue which indicates coolant contamination.
- Test Every Button: The Sync infotainment system can be buggy; ensure the screen and cameras work.
- Smell the Interior: Musty smells can indicate a clogged AC drain line or a leaking sunroof seal.
- Drive at Highway Speeds: Feel for vibrations that might suggest a bent driveshaft or unbalanced tires.
If the seller won’t let you take the car to an independent mechanic for a professional inspection, that is a massive red flag. A professional inspection usually costs about $150, but it can save you thousands in the long run.
Frequently Asked Questions About ford explorer suv reliability reviews
