The fifth-generation Ford Explorer (U502) marks a radical turning point in the model's history. Abandoning the ladder frame for a unibody structure (D4 platform shared with the Ford Taurus and the first-generation Volvo XC90), it transitions from a true off-roader to a large family SUV (crossover) prioritizing ride comfort. Offered in FWD or AWD, it underwent a major facelift in 2016 (redesigned front end, new 2.3L EcoBoost engine, technological improvements) and a minor update in 2018. Although extremely popular in North America, its overall reliability is rated below average by organizations like J.D. Power and Consumer Reports, primarily due to chronic weaknesses in the AWD system (PTU), the water pump on V6 engines, and the SYNC infotainment system.
The Ford Explorer V (U502) offers undeniable space and comfort for large families, with an imposing look. However, its reliability record is marred by costly design flaws. Buying a V6 model (naturally aspirated 3.5L or EcoBoost) is a risky bet without formal proof of a recent internal water pump replacement and regular transfer case (PTU) fluid changes for AWD versions. The 4-cylinder versions (2.0L and 2.3L EcoBoost) are generally less problematic mechanically. Favor a facelifted model (2016+) to benefit from the much more stable SYNC 3 system, and ensure that the numerous rear suspension recalls have been performed.
