Common Issues and Reliability of the 2015 Ford Explorer 3.5L Twin Turbo

Alright, let's talk about the nitty-gritty. No car is perfect, and the 2015 Ford Explorer 3.5L Twin Turbo is no exception. While it's a fantastic vehicle, it does come with a few potential issues that owners should be aware of. Knowing these can help you stay ahead of the game and keep your Explorer running smoothly. Let's dig in!

  • Water Pump Failures: One of the more common issues reported by owners is water pump failure. The water pump is a critical component responsible for circulating coolant throughout the engine.

Regular transmission fluid changes and inspections can help prevent these problems. If you notice any unusual behavior from your transmission, it's best to have it checked by a qualified mechanic.
  • Carbon Buildup: Direct-injection engines, like the 3.5L EcoBoost, are prone to carbon buildup on the intake valves. This buildup can reduce engine performance and fuel efficiency. Regular use of fuel additives designed to clean the fuel system and intake valves can help mitigate this issue. If the problem persists, a professional cleaning might be necessary.
  • Electrical System Issues: Electrical problems, such as issues with sensors, wiring, or the computer system, can also occur. These can lead to a variety of symptoms, including warning lights, erratic engine behavior, and difficulty starting the vehicle. Having your car's electrical system inspected regularly is a smart way to address potential problems early.
  • Routine Maintenance: Regularly scheduled maintenance is key to preventing major issues. Following the manufacturer's recommended maintenance schedule for oil changes, filter replacements, and other services will help ensure your Explorer runs reliably for years to come. Make sure you use high-quality parts and fluids to keep the engine and related components in top condition.
  • Preventative Measures: To minimize potential issues, consider performing preventative maintenance tasks like regularly checking fluid levels, inspecting belts and hoses, and listening for any unusual noises. Address any symptoms you notice right away, as this can prevent minor issues from becoming major problems. Knowing the common issues and taking preventive measures will help you enjoy your 2015 Ford Explorer 3.5L Twin Turbo for a long time!

Performance and Modifications

For those of you who like to tinker and squeeze every ounce of performance out of your ride, the 2015 Ford Explorer 3.5L Twin Turbo offers a solid platform for modifications. Whether you're looking to boost horsepower, improve handling, or simply give your Explorer a unique look, there are plenty of options. Let's explore some popular modification paths:
