FORD Explorer — What to know
The Explorer is Ford's mid-size SUV with a broad service network. The 3.5 EcoBoost V6 (2011–2019) is the most popular engine and is generally reliable. Known issues include cabin exhaust fume intrusion on 2011–2017 models and carbon buildup on EcoBoost direct injection engines.
What is this repair?
Plain-English overview
Solenoids, relays and fuses are the switching components of the electrical system; a failed relay can prevent a system from operating while a starter solenoid failure prevents the engine from cranking. Diagnosis to pinpoint the exact faulty component is often quicker than the replacement itself.
Warning signs
How to tell your FORD Explorer needs this repair
- A system (fuel pump, cooling fan, starter) completely failing to operate
- Clicking sound when attempting to start (starter solenoid failure)
- Intermittent electrical fault that clears when tapping a component
- Blown fuse that returns repeatedly (indicates an underlying short)
- Battery voltage dropping — voltage regulator failure overcharges or undercharges
Common causes
Why FORD Explorer vehicles need this repair
- 1.Worn brushes or commutator inside the motor from high-cycle use
- 2.Faulty solenoid failing to engage the starter ring gear
- 3.Oil contamination from leaking seals near the starter
- 4.High mileage causing internal winding failure
What affects the price
Why your quote may differ
- Whether the fault is a single component or part of a broader electrical issue
