The 2006–2010 Ford Explorer covers the 4th gen generation from start to finish. Mechanically these years are the same car — same platform, same engine family, same failure points — so shop the individual car's condition and service history rather than chasing a specific model year. V8 with maintenance records is the safer pick. 4.0L SOHC timing chain is a red flag.
Bottom line: Only with verified maintenance records and a thorough pre-purchase inspection.
Don't stop at researching the model — get a verdict on the exact car you're looking at.
This score covers 2006–2010 only. The model guide scores the Explorer across all generations.
This generation launched in 2006: Body-on-frame, revised suspension, refined V6/V8 options. Powertrain and core hardware carry over across the span, which is exactly why we cover the whole generation on one page instead of splitting near-identical years apart.
Across 2006–2010, reliability tracks the generation as a whole rather than any one model year. Early-build cars (2006–2007) carry the usual first-run risk, and late-run cars have had years of TSB and running fixes applied. The issues that actually decide whether a car is worth buying: Timing chain issues on 4.0L SOHC (rare but expensive); 5R55 transmission failures on higher-mileage cars; Rear differential seal leaks.
Bring this list to your pre-purchase inspection.
Expect Explorer maintenance costs typical of the 4th gen generation. Engines: 4.0L SOHC V6 / 4.6L 3V V8. Transmissions: 5-speed automatic / 6-speed automatic (V8). Budget for the usual service intervals (oil, brakes, cooling, transmission fluid) plus preventative work on the known-weak items above. Parts for a 2010 Ford Explorer are cheap and widely available.
Focused on what tends to fail on the 4th gen generation.
Within 2006–2010, condition and maintenance history beat model year almost every time. Later cars in the span are typically the most sorted; earlier cars are the cheapest way into the generation. If a 2006–2010 Ford Explorer passes a pre-purchase inspection with the known weak points checked, it's a defensible used buy. Strengths in this generation: Tows well, Simple mechanicals.
Best for: Buyers cross-shopping the whole 4th gen generation of the Ford Explorer rather than one specific model year.
The 2011–2019 generation brings newer powertrains and driver assistance at a higher price.
Verdict rates it 4.0/5 for reliability and 3.9/5 as a buy. The faults that decide a given car are listed below — check those, not the badge.
