2004 Jaguar S-Type Problems
RepairPal has identified the most common problems with the 2004 Jaguar S-Type based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The plastic coolant reservoir is prone to leak. The reservoir can mysteriously lose coolant or coolant may pool under the engine compartment. If this occurs, the coolant reservoir should be inspected for cracks. If leaks are neglected, the reservoir may fail and cause the engine to overheat.
Premature automatic transmission failure is common. Diagnoses of the fault will be necessary to determine if repair or replacement is the proper repair.
The front and/or rear window regulators are prone to failure. A failed window regulator will require replacement.
Improved coolant hoses that are able to withstand cooling system pressure are available (Jaguar Service Bulletin S518). These improved hoses help avoid engine overheating by preventing the coolant hose from inadvertently detaching from the engine.
A plastic component in the HID head light may fail and cause the head light to point toward the ground. The adjuster—which is very expensive—needs to be replaced to fix the problem.
