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
  • Starter solenoid accessibility — sometimes easier via the top, sometimes the underside
  • Fuse box access and component identification (requires wiring diagram)

The cost varies by year, engine size, and your location. Use the estimator above for an accurate breakdown of parts and labour specific to your FORD Explorer.

Common parts for this repair include: Starter solenoid.

Starter solenoid replacement on a FORD Explorer typically takes 1.5–4.5 hours of labour at a garage.

For a FORD Explorer, starter solenoid replacement is typically needed as needed; relays and fuses fail unpredictably; voltage regulators typically at 80,000–130,000 miles.

Always ask for an itemised quote showing parts cost and labour time separately. Research the cost of the specific parts required online — the part number is often readable from the old component. Compare the labour hours quoted against RepairFair's estimate for your specific FORD model and year. A quote that is 20–30% higher than RepairFair's estimate warrants a second opinion. Ask whether aftermarket or OEM parts are being used, and whether a remanufactured option is available — both legitimate choices, but you should always know which one you are paying for.

For most repairs, a reputable independent with experience on FORD vehicles is the better value choice — typically 30–50% less in total cost for the same quality outcome. The scenarios where a dealer makes sense are: work covered by a manufacturer or extended warranty, recalls or technical service bulletins requiring dealer-level software, and complex electronic programming that requires proprietary tools not yet available to independents. For mechanical repairs, an independent using quality parts is equivalent to a dealer in terms of outcomes and often exceeds dealer service in the attention given to each job.

Quality aftermarket parts from reputable tier-1 manufacturers are appropriate for most FORD repairs. The distinction is between tier-1 aftermarket (Bosch, Denso, Delphi, Gates, SKF, Brembo — brands that supply car manufacturers as original equipment) and budget unbranded parts. Tier-1 aftermarket parts perform identically to OEM and often cost 30–60% less. The components where OEM is genuinely preferable are safety-critical items with tight tolerances (airbag modules, antilock brake modulators), items with FORD-specific software coding (ECU, certain sensors), and components where the OEM part has been specifically improved over earlier versions that were prone to failure.

When any system component is replaced, it is worth inspecting nearby components that share labour time. Replacing one part while the relevant area is already disassembled often costs very little in extra labour compared with doing it as a separate job later. Ask your mechanic to inspect adjacent components and report their condition during the repair. Any part that is visibly worn or leaking and is accessible during the main repair is worth addressing at the same time — this is good planning, not upselling, when the mechanic can clearly show you the condition of the component in question.

At 1.5–4.5 hours of labour this repair requires a solid level of mechanical knowledge and the proper tools. Most owners prefer to use a professional to ensure the job is done correctly and backed by a parts-and-labour warranty.
