Common 2012 ford explorer problems and Solutions
Every vehicle has its “achilles heel,” and for the 2012 Explorer, there are several distinct areas where the engineering falls short. The most documented 2012 ford explorer problems involve the steering rack, the cooling system, and the transmission. Understanding these helps you prioritize your maintenance budget.
Early detection is the key to preventing a breakdown in the middle of a trail or a busy highway. We see many owners ignore small vibrations or faint smells, only to find themselves stranded later. Let’s break down these issues by system so you can check your own vehicle systematically.
The EPAS Power Steering Failure
The transition to Electronic Power Assisted Steering (EPAS) was a major shift for Ford, but the 2012 model year suffered from significant reliability issues. Owners often report a sudden loss of power steering while driving, accompanied by a Service Power Steering Now warning on the dash. This is one of the most dangerous 2012 ford explorer problems because it makes the heavy SUV very difficult to maneuver at low speeds.
The culprit is usually a faulty sensor or a motor failure within the steering rack assembly. Ford issued recalls for many of these units, so your first step should always be checking your VIN on the NHTSA website. If your vehicle is not covered, a full rack replacement is often the only permanent fix.
For the DIYer, replacing a steering rack is a labor-intensive job that requires subframe support and a professional alignment afterward. If you feel a “notchy” sensation in the wheel or hear a grinding noise when turning, do not wait. Address the steering system immediately to ensure your safety on the road.
The Internal Water Pump Nightmare
If you have the 3.5L Ti-VCT V6 engine, you need to be aware of the internal water pump design. Unlike most vehicles where the pump sits outside the engine, this pump is driven by the timing chain inside the engine front cover. When the pump’s internal seals fail, it leaks coolant directly into the engine oil.
This creates a “chocolate milk” sludge that destroys engine bearings in a matter of miles. Check your oil dipstick frequently for any signs of milky discoloration or a sudden rise in oil level. You might also notice a sweet smell of coolant or a small puddle near the front of the engine from the weep hole.
Replacing this pump is a massive undertaking for a DIY mechanic, as it involves timing the engine and removing the front cover. Expect to spend 10 to 12 hours on this job. If you see coolant loss without a visible external leak, stop driving immediately and investigate the water pump.
Transmission Hesitation and Shifting Issues
The 6F55 6-speed automatic transmission in the 2012 Explorer is generally robust but can develop “hunting” or harsh shifts. Many owners complain about a lunging sensation when downshifting or a delay when shifting from Park to Drive. These 2012 ford explorer problems are often related to the Transmission Control Module (TCM) software or worn solenoids.
Before assuming you need a new transmission, try a simple fluid exchange. Note that I said “exchange,” not a high-pressure flush, which can dislodge debris and cause more harm. Use only Motorcraft Mercon LV fluid to ensure compatibility with the internal clutches.
If the fluid change doesn’t help, a software “relearn” at the dealership might solve the shifting logic issues. For off-roaders who tow frequently, installing an auxiliary transmission cooler is a smart mod. It keeps fluid temperatures down during heavy strain, extending the life of the internal components significantly.
Diagnosing Transmission Solenoid Faults
If your Explorer is throwing a check engine light with codes like P0750 or P0760, you likely have a shift solenoid issue. You can test these solenoids with a multimeter by checking the resistance at the transmission connector. This is a great task for a weekend DIYer who wants to save thousands over a full rebuild.
Always check the wiring harness for signs of heat damage or rodent chewing before replacing parts. A frayed wire can mimic a mechanical failure and lead to unnecessary repairs. Clean the connectors with electrical contact cleaner to ensure a solid signal between the TCM and the gearbox.
Body and Interior: Paint Bubbling and Electronics
While mechanical issues are the priority, the 2012 Explorer has some frustrating aesthetic and electronic quirks. The most common body complaint is paint bubbling on the leading edge of the aluminum hood. This is caused by iron contamination during the manufacturing process, leading to galvanic corrosion under the paint.
Inside the cabin, the MyFord Touch system is a frequent source of headaches. Users report the screen freezing, failing to recognize Bluetooth devices, or the backup camera going dark. While these aren’t safety risks like steering failure, they certainly impact the daily driving experience.
- Hood Corrosion: Sanding and repainting is often a temporary fix; many owners choose to install a bug deflector to hide the bubbling.
- Sync Updates: Ensure your system is running the latest software version by downloading updates from the Ford owner portal onto a USB drive.
- Rear Camera: If the camera is intermittent, check the wiring harness inside the liftgate, as it can pinch over time.
Essential Tools for Troubleshooting 2012 Ford Explorer Problems
To tackle these 2012 ford explorer problems effectively, you need more than just a basic wrench set. Modern SUVs rely heavily on sensors and modules, so your diagnostic kit needs to be up to date. Here are the tools I recommend for any Explorer owner who wants to do their own maintenance.
- OBD-II Scanner with Live Data: A basic code reader is okay, but a scanner that shows live fuel trims and sensor voltages is better.
- Coolant Pressure Tester: This is vital for finding those elusive leaks before they turn into engine-killing failures.
- Digital Multimeter: Essential for testing the battery, alternator, and various electrical sensors.
- Torque Wrench: Critical for suspension and engine work where bolt tension must be exact to prevent leaks or failures.
- FORScan Software: This is a powerful tool for Ford owners that allows you to access dealer-level diagnostics and module programming via a laptop.
Having the right tools doesn’t just make the job easier; it makes it safer. When working under the vehicle, always use heavy-duty jack stands and never rely on the factory bottle jack. Safety is the first priority for any DIY project.
Safety First: When to Stop and Call a Pro
DIY repair is rewarding, but knowing your limits is part of being an expert mechanic. Some 2012 ford explorer problems require specialized equipment that the average garage simply doesn’t have. If you find yourself in the following situations, it is time to call a licensed professional.
First, anything involving the timing chain or internal engine components is high-risk. If the engine timing is off by even a single tooth, you risk catastrophic valve damage. If you don’t feel comfortable “pinning” the cams, let a pro handle the water pump replacement.
Second, the EPAS steering system often requires a software initialization after the rack is replaced. Without the proper scan tool to “marry” the new rack to the vehicle’s computer, the power assist may not activate. Check with a local shop to see if they can perform the programming if you do the mechanical install yourself.
Finally, if you are dealing with fuel system leaks or pressurized AC components, exercise extreme caution. Gasoline is highly flammable, and AC refrigerant requires professional recovery to protect the environment and your health. Don’t take shortcuts with safety to save a few dollars.
Frequently Asked Questions About 2012 ford explorer problems
