The 2014 Explorer is a capable three-row SUV undermined by serious powertrain reliability issues, particularly catastrophic engine failures in EcoBoost models and widespread transmission problems across the lineup.
3.5L EcoBoost Catastrophic Engine Failure (Coolant Intrusion)
Occasional · high severityTypical onset: 80,000-150,000 mi
Symptoms: White smoke from exhaust on cold start, Rapid coolant loss with no external leaks, Milky oil on dipstick or oil cap, Misfires and rough idle that progressively worsen, Hydrolocked cylinders requiring tow-in
Fix: Internal coolant leak from failed cylinder head or block casting porosity allows coolant into cylinders, destroying bearings and requiring complete engine replacement or full rebuild. 18-25 labor hours for long block swap.
Estimated cost: $8,000-12,000
2.0L EcoBoost Overheating and Head Gasket Failure
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Coolant loss without visible leaks, Overheating under load or highway driving, White exhaust smoke, Rough idle and cylinder misfires, Oil contamination with coolant
Fix: Head gasket failure common on 2.0L EcoBoost, often combined with warped head requiring machining. Some cases progress to complete engine failure. 12-16 labor hours for head gasket replacement, both heads if needed.
Estimated cost: $3,500-6,500
6F50/6F55 Transmission Shudder and Internal Failure
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Harsh shudder during 4-5-6 gear shifts especially under light throttle, Delayed engagement when shifting to drive or reverse, Slipping between gears under acceleration, Check engine light with transmission codes P0735, P0741, P0744
Fix: Torque converter clutch failure and valve body issues plague these 6-speed automatics. Fluid and filter service sometimes helps early cases, but most need transmission rebuild or replacement. 8-12 labor hours for R&R and rebuild.
Estimated cost: $3,500-5,500
PTU (Power Transfer Unit) Failure
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: Grinding or whining noise from center of vehicle, Vibration during acceleration, Metal shavings in PTU fluid during service, Complete loss of AWD function, Burning smell from underneath vehicle
Fix: PTU fails from inadequate factory fluid service interval (Ford says lifetime, reality is 30k-40k intervals needed). Once internal damage occurs, complete PTU replacement required. 4-6 labor hours.
Estimated cost: $1,800-2,800
Rear Axle Hub and Bearing Assembly Failure
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Humming or growling noise from rear that increases with speed, ABS warning light illumination, Wheel speed sensor codes, Excessive wheel play when jacked up
Fix: Rear hub bearings fail prematurely, often one side then the other within 20k miles. Related to NHTSA recalls but failures continue. Hub assembly replacement required per side. 2-3 labor hours per side.
Estimated cost: $400-700 per side
Front Suspension Lower Control Arm Bushing Failure
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Clunking over bumps from front end, Wandering or loose steering feel, Uneven tire wear on inside edges, Excessive movement visible during brake application
Fix: Front lower control arm bushings tear and separate, causing alignment issues and handling problems. Replace complete control arms both sides for long-term fix. 3-4 labor hours both sides with alignment.
Estimated cost: $800-1,200
Panoramic Sunroof Drain Clogs and Water Leaks
Common · low severitySymptoms: Water dripping from headliner at A-pillars or overhead console, Wet front footwells after rain or car wash, Musty smell in cabin, Water staining on headliner
Fix: Sunroof drain tubes clog with debris, causing water to overflow into cabin. All four drains need clearing and sometimes tube replacement if kinked. 1-2 labor hours if tubes intact.
Estimated cost: $150-400
Hard pass unless priced $3,000-4,000 below market to cover inevitable powertrain repairs—the EcoBoost engines and transmissions have unacceptable failure rates for a modern vehicle.
