Premature automatic transmission failure is common. Diagnoses of the fault will be necessary to determine if repair or replacement is the proper repair.
Jaguar S-Type Problem Reports
Most Reported Jaguar S-Type Problem Reports
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.
The front and/or rear window regulators are prone to failure. A failed window regulator will require replacement.
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.
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.
oil leak from oil pan gasket. Not repaired yet.
On this V8 engine, timing chain problems are very common. Because the timing chain tensioners were made from plastic, they can fail prematurely and cause serious engine damage. A noticeable engine noise while idling or during a cold start can indicate a timing chain tensioner problem. The engine noise may also be accompanied by a rough or uneven engine idle. Improved components are available to remedy this problem.
