Ford Explorer Generations: What to Know
To evaluate reliability and value, it's essential to understand the major changes across Explorer generations. Let’s take a look at each one and what defines it.
First Generation (1991–1994)
The original Ford Explorer was based on the Ford Ranger platform and featured a body-on-frame construction. It was available in two- and four-door body styles and offered rear- or four-wheel drive. While it’s now considered a classic, finding a well-maintained first-gen Explorer today is rare, and reliability is questionable due to age.
Second Generation (1995–2001)
This generation brought significant improvements in comfort and safety. It introduced side airbags and a more refined interior. However, it's also the generation associated with the Firestone tire controversy and rollover risks, especially when equipped with certain tire brands. These models are now over 20 years old, so mechanical wear and rust are common concerns.
Third Generation (2002–2005)
The 2002 redesign introduced a more aerodynamic design and improved ride quality. This model was still body-on-frame and offered a V8 option for the first time. Common issues include transmission problems, especially with the 5R55S automatic transmission, and cooling system failures. Rust, particularly in northern climates, is also a concern.
Fourth Generation (2006–2010)
Known for its boxy, truck-like appearance, the fourth-gen Explorer continued with body-on-frame construction. It offered three rows of seating and available V8 power. Reliability during these years was mixed. The 4.6L V8 engine is generally durable, but the 4.0L V6 had issues with timing chain tensioners and overheating.
Additionally, the 6R60 transmission began to show signs of shuddering and slipping, especially in higher-mileage vehicles. Power steering pump failures are also frequent in this generation.
Fifth Generation (2011–2019)
This was a major shift: the Ford Explorer switched to unibody construction and front-wheel drive-based architecture, sharing its platform with the Ford Taurus. This change improved fuel economy, ride comfort, and handling. The fifth generation is widely considered one of the most reliable, especially from 2011 to 2016.
Engine options included a 3.5L V6, a turbocharged 2.0L EcoBoost four-cylinder (2013–2014), and a 3.5L twin-turbo EcoBoost V6. The 3.5L naturally aspirated V6 is praised for its longevity, while the EcoBoost engines offer strong performance with good fuel efficiency.
Common issues in this generation include:
- Timing chain tensioner problems in 2011–2012 models
- Transmission hesitation in early 2011 models
- Water pump failures in EcoBoost engines
- SYNC infotainment system glitches
Despite these issues, later models (2016–2019) saw significant improvements in build quality and technology.
Sixth Generation (2020–Present)
The current Ford Explorer features a sleek, modern design, improved aerodynamics, and advanced driver assistance features. It offers a range of powertrains, including a 2.3L EcoBoost four-cylinder, a 3.0L twin-turbo V6, and a hybrid version. The platform is based on the Ford CD6 architecture, shared with the Lincoln Aviator.
Early reliability reports are generally positive, with praise for the smooth ride, responsive handling, and updated interior tech. However, some 2020–2021 models reported issues with the transmission (particularly hesitation during acceleration) and SYNC 4 system bugs. These have largely been addressed in later model years.
