There is no denying that the Explorer is one of the most influential SUV models that has hit the market. There are millions of them on the road right now and it continues to be a sales success as time goes on (via Motor 1).

However, numerous issues happen to the Explorer models as time goes on, and many of these are very expensive to repair. The main issues that happen to the older Explorer models are the suspension going out and the transmission starting to slip. These repairs are crucial to the driving quality of the vehicle.
