Common Battery Issues in the 2017 Ford Explorer

Experiencing battery problems with your 2017 Ford Explorer? You're definitely not the only one! It's super common for Explorers of this year to run into some frustrating issues with their batteries. Let's break down the most frequent culprits behind these problems, so you can get a better handle on what might be happening with your ride. One of the main issues is a dead battery. You hop in your Explorer, turn the key, and... nothing. This can happen for several reasons, such as leaving the lights on, a door ajar, or if the battery is simply old and worn out. Over time, batteries lose their ability to hold a charge, especially with extreme temperatures. Another common problem is excessive battery drain. This means something in your car is constantly drawing power, even when the engine is off. It could be a faulty sensor, a malfunctioning module, or even aftermarket accessories that weren't installed correctly. This drain can quickly deplete your battery, leaving you stranded. Corrosion on the battery terminals can also cause issues. Corrosion is that white or bluish buildup you sometimes see on the terminals. It can prevent a good connection between the battery and the car's electrical system, leading to starting problems or other electrical glitches. Keeping those terminals clean is crucial for optimal battery performance. Problems with the alternator are also a major cause of battery issues. The alternator is responsible for charging the battery while the engine is running. If the alternator isn't working correctly, it won't properly recharge the battery, leading to a dead or weak battery over time. A faulty alternator can manifest in several ways, such as dimming headlights, a battery warning light on the dashboard, or even stalling. Lastly, short trips can also contribute to battery problems. If you primarily drive short distances, the alternator may not have enough time to fully recharge the battery after each start. This can lead to a gradual decline in battery health and eventually, a dead battery. Ensuring you take longer drives occasionally can help keep your battery properly charged and extend its lifespan.

Diagnosing the Battery Problem

Alright, so you're dealing with a potentially dead battery in your 2017 Ford Explorer. What's next? Well, figuring out exactly what's causing the issue is the first step to getting it fixed. Let's run through some simple diagnostic steps you can take to pinpoint the problem. Start with the basics. Check the battery terminals for any signs of corrosion. Use a wire brush or a battery terminal cleaner to remove any buildup. Corrosion can prevent a good connection, so cleaning them up is a quick and easy way to rule out a simple fix. Next, test the battery voltage with a multimeter. A healthy battery should read around 12.6 volts when the engine is off. If it's significantly lower, like below 12 volts, your battery might be on its last legs. You can pick up a multimeter at most auto parts stores, and they're pretty straightforward to use. Now, let's move on to checking for parasitic drain. This involves using a multimeter to measure the current draw when the car is off. To do this, you'll need to disconnect the negative battery cable and connect the multimeter in series between the cable and the battery terminal. A normal parasitic draw should be less than 50 milliamps. If you're seeing a higher reading, something is draining power while the car is off. Identifying the source of the drain can be tricky, but start by pulling fuses one at a time to see if the current draw drops. If it does, you've found the circuit that's causing the problem. Don't forget to inspect the alternator. The alternator charges the battery while the engine is running. If it's not working correctly, your battery won't stay charged. You can test the alternator's output voltage with a multimeter while the engine is running. It should be between 13.5 and 14.5 volts. If it's outside this range, the alternator might be faulty. You can also take your car to an auto parts store, where they can often test the alternator for free. Pay attention to any warning lights on your dashboard. The battery light or the check engine light can sometimes indicate a problem with the battery or charging system. If these lights are on, it's a good idea to get your car scanned for trouble codes. These codes can provide valuable clues about what's going on. Lastly, consider the age of your battery. Car batteries typically last between 3 to 5 years. If your battery is older than that, it might simply be time for a replacement. Even if it seems to be working fine, an old battery can fail unexpectedly. Note down all your findings to help you or a mechanic diagnose the problem accurately. A systematic approach will save you time and money in the long run.

Step-by-Step Solutions

Okay, so you've figured out what's causing your 2017 Ford Explorer's battery woes. Now, let's get into the nitty-gritty of fixing it! Here are some step-by-step solutions you can try to get your battery back in tip-top shape. Start with the easiest fix: cleaning the battery terminals. If you found corrosion on the terminals during your diagnosis, disconnect the battery cables (negative first!), and use a wire brush or battery terminal cleaner to scrub away the corrosion. Once they're clean, apply a bit of dielectric grease to prevent future corrosion. This simple step can often resolve starting issues and improve overall battery performance. If your battery is old or failing, the best solution is to replace it. Head to your local auto parts store and get a new battery that's compatible with your 2017 Ford Explorer. When installing the new battery, make sure to connect the positive cable first, followed by the negative cable. Double-check that the terminals are secure and give the battery a good test drive. Dealing with parasitic drain can be a bit more involved. If you identified a circuit that's causing the drain by pulling fuses, investigate the components on that circuit. It could be a faulty sensor, a malfunctioning module, or even an aftermarket accessory that's not wired correctly. Consult a wiring diagram for your Explorer to help you trace the circuit and identify the culprit. If you're not comfortable doing this yourself, it's best to take your car to a professional mechanic. If the alternator is faulty, it's essential to replace it to ensure your battery stays charged. Replacing the alternator typically involves removing the serpentine belt, disconnecting the electrical connections, and unbolting the alternator from the engine. Install the new alternator in the reverse order, making sure to properly tension the serpentine belt. Again, if you're not experienced with this type of repair, it's best to leave it to a professional. Regularly check and maintain your battery. Use a battery tester to monitor its voltage and health, especially before long trips or during extreme weather. If you notice any signs of weakness, such as slow cranking or dimming lights, address the issue promptly to prevent a dead battery. Additionally, avoid leaving your car unused for extended periods, as this can lead to battery drain. If you're storing your car, consider using a battery maintainer to keep the battery charged.
