Specs side by side
What owners say
Explorer
Overall
Mixed sentiment with a clear generational divide. The current-generation Explorer (2020+) is frequently praised for its spacious interior, particularly the generous cargo and third-row space, comfortable ride, and strong performance in ST and Platinum trims. The 3.0L EcoBoost V6 in performance models is highlighted as a standout feature, providing a fun and powerful driving experience.
Best version to buy
Explorer ST (2020+): The ST trim is specifically recommended by owners for its engaging 400-horsepower 3.0L EcoBoost V6 engine, which transforms the driving experience and is described as "a blast to drive." It is noted for retaining practicality while offering performance that makes it enjoyable for the driver. The Platinum trim is also mentioned as a top choice for maximizing luxury features.
Known issues
- Transmission reliability problems: Includes rough shifting, laggy response, complete failure, and concerns about longevity. Noted as a weak point across the model line, with failures occurring at both low and high mileage.
- Engine and cooling system problems: Reports of engines overheating, internal flooding, and repeated catalytic converter failures requiring multiple replacements. Frequency: recurrent.
- General reliability concerns: Broad statements about Ford reliability being "average to below average," with specific mentions of expensive repairs and the need for significant maintenance budgets. Frequency: recurrent.
Flex
Overall
Mixed to highly positive among owners, with sentiment heavily dependent on powertrain choice and awareness of a critical, well-known mechanical flaw. Owners express deep affection for the vehicle's unique boxy styling, exceptional passenger comfort across three rows, versatile cargo space, and car-like driving dynamics that avoid the bulkiness of traditional SUVs. The EcoBoost turbocharged V6 engine is frequently praised for strong, satisfying acceleration, making the vehicle a "rocket" or "sleeper." However, this enthusiasm is tempered by a very frequent and severe criticism: the failure-prone internal water pump design on the 3.5L V6 engines (both naturally aspirated and EcoBoost), which can lead to catastrophic engine failure and is described as a matter of "when, not if." Fuel economy is consistently criticized as poor (16-20 MPG combined is typical), exacerbated by a small fuel tank, making it a primary reason owners seek replacements.
Best version to buy
Limited trim with EcoBoost engine and AWD. The Limited trim is associated with premium features like leather, rear climate control, and advanced technology.
Known issues
- Internal water pump failure: Design flaw where the pump is located inside the engine timing cover; failure can leak coolant into the oil pan, leading to catastrophic engine seizure without obvious external leaks.
- Poor fuel economy: Real-world combined mileage reported between 16-20 MPG, with a small fuel tank leading to frequent fill-ups. A primary reason owners seek to replace the vehicle. Frequency: very frequent.
- Rust and corrosion: Significant rust issues reported, particularly on door tops under weather stripping, rear hatch seams, and exhaust components (e.g., "flex pipe"). Frequency: recurrent.
