FORD Explorer — What to know
The Explorer is Ford's mid-size SUV with a broad service network. The 3.5 EcoBoost V6 (2011–2019) is the most popular engine and is generally reliable. Known issues include cabin exhaust fume intrusion on 2011–2017 models and carbon buildup on EcoBoost direct injection engines.
