2003 Ford Explorer Sport Trac Problems

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.

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.

Replace the worn wheel bearings.

2003 Ford Explorer Sport Trac Reviews

Great truck (75,000 miles) with one big exception. Three times, in as many months,after parking it has failed to start. First diagnosis "faulty alarm" ($ 600.00) Next diagnosis "bad fuel pump" This is costing me $ 720.00. After this I'm not sure what to do if the problem continues...

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...

I have a 2003 Ford Explorer Sport Trac. Except for the alternator going out at 85,000 miles, it's been a pretty good truck. Now, I have an issue with my brakes squeaking when I back up - only when I back up. I've spent $500 on new brakes, calipers, etc and it still squeaks. My mechanic even put in Ford parts - no change. It's very annoying
