2003 Mercury Mountaineer Problems

Problems With 5-speed Automatic Transmission are Common

Various problems with the 5-speed automatic transmission were common. These problems can be more common on the 2002 models with build dates before March, 2002. There are many service bulletins describing the diagnoses and repairs, which include fluid leak repairs, transmission software updates, or internal failures requiring a costly repair.

Crack on Lift Gate

A cosmetic crack may develop on the plastic liftgate trim panel. Our technicians tell us the Ford has released a service procedure to replace the applique without damage the the liftgate glass.

Plastic Intake Manifold May Crack Causing Coolant Leak

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.
