According to RepairPal data, these Explorers averaged 0.8 repair visits per year compared to 0.5 for competitors.
2020-2023: Redesign Growing Pains
The sixth-generation Explorer’s launch was marred by problems including:
- Transmission shudder during cold starts (documented in NHTSA Campaign #22V-543)
- Electrical faults in the SYNC 4 system causing backup camera failures
- Engine stalling in the 3.0L EcoBoost V6 models
Consumer Reports initially gave these models a dismal 1/5 predicted reliability rating and explicitly warned buyers to avoid the 2023 model.
Common Ford Explorer Problems
Knowing what typically breaks can help you budget for repairs or watch for warning signs:
Transmission Issues
Transmission problems have historically been the Explorer’s Achilles’ heel:
- Failure symptoms: Harsh shifts, slipping gears, or total failure
- Repair cost: $3,800-$5,200 for a complete rebuild
- Most affected years: 2002-2006, 2020
For 2020+ models, many transmission shudder issues can be resolved with software updates or replacement of specific components rather than entire transmissions.
Engine Problems
Engine reliability varies significantly by powerplant:
| Engine | Common Issues | Reliability Rating | Years Affected |
|---|---|---|---|
| 2.3L EcoBoost I4 | Timing chain stretch | Moderate | 2013-2015 |
| 3.0L EcoBoost V6 | Carbon buildup, fuel injector failures | Fair | 2020-2022 |
| 3.5L V6 (non-turbo) | Water pump leaks | Good | 2011-2019 |
| 5.0L V8 | Relatively few issues | Very Good | 2011-2019 |
The non-turbocharged engines generally prove more reliable long-term than their EcoBoost counterparts, which require more maintenance.
Electrical System Failures
Electrical issues plague certain Explorer generations:
- Malfunctioning power windows and locks
- Dead instrument clusters
- Backup camera failures
- Battery drain issues
These problems appear most frequently in 2006-2010 models and again in 2020-2022 versions, though dealer software updates have resolved many issues in newer models.
Maintenance Costs: What to Expect
Owning an Explorer isn’t cheap. The average annual maintenance cost is $732 according to RepairPal, significantly higher than the midsize SUV average of $573.
Key maintenance items include:
| Service | Interval | Cost | Importance |
|---|---|---|---|
| Oil changes | Every 5,000-7,500 miles | $75-$125 | Essential |
| Transmission fluid | Every 30,000-60,000 miles | $150-$250 | Critical for longevity |
| Timing belt/chain | 100,000 miles | $1,200-$1,800 | Prevents catastrophic failure |
| Differential/transfer case fluid | Every 60,000 miles | $120-$200 | Prevents $4,000+ repairs |
Following Ford’s recommended maintenance schedule isn’t just good advice—it’s essential for Explorer reliability. Owners who stick to the schedule report 40% lower repair costs over a decade.
How Explorer Reliability Varies By Trim
Not all Explorer trims are created equal when it comes to reliability:
