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.

2003 Ford Explorer Sport Trac Problems
A failed heater blend door or actuator can cause the temperature control for the HVAC system to stop working. A clicking sound from the dash area would commonly indicate an actuator fault. If the heater gets stuck on the hottest setting, the heater blend door may be broken requiring replacement of the heater box to repair the issue.
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.

We have had our 03 SportTrac since Oct 2009, and the only problem I should mention is the crappy positioning of the inerita switch right under the passenger dashboard. If you have a long legged person riding shotgun, you need to make them aware not to put their feet too far up under the dashboard by the passenger door, or YOUR TRUCK WILL LOSE FUEL TO THE ENGINE AND YOU WILL LOSE POWER STEERING!!!
