The 2005 Mercury Mountaineer Premier is a moderately easy car to maintain. Its fog light is reliably accessible by simply reaching behind the front bumper. Its battery is also easily accessible, with open access to both its terminals and its bracket, allowing for a simple repair procedure. The engine air filter is easy to replace as well, with no tools needed to disengage its housing and the filter itself sliding out with ease.
However, the 2005 Mercury Mountaineer Premier does have its share of pain points. The tail lights will require some screws to be removed before their housing can be wiggled out. The non-LED center brake lights will need more attention paid to them over time, and removing their housing is also rather tedious. The spare tire’s location underneath the vehicle may lead to problems with it rusting to the vehicle, which will be inconvenient in the event of a flat.
