Maintenance
|
Service Intervals
|
Oil Change Interval:
|
Typically every 5,000-10,000 miles (8,000-16,000 km) or 12 months, depending on driving conditions and oil used (refer to manual for specific model/engine).

|
Known Issues
|
Engine 1.8T:
|
Oil sludge buildup (requires regular maintenance), PCV system failures, coil pack failures, coolant flange leaks, turbocharger issues.
|
Engine 2.0L Alt:
|
Oil consumption issues, timing chain tensioner problems, intake manifold flap issues.
|
Engine 3.0 V6:
|
Timing chain guides and tensioners can wear, leading to noise and potential damage; coolant leaks, particularly from the water pump and thermostat housing.
|
Suspension:
|
Worn control arm bushings and ball joints can lead to steering looseness and premature tire wear. Knocking noises from the front suspension are common indicators.
|
Electrical:
|
Window regulator failures, door lock module issues, HVAC blower motor resistor failures, instrument cluster pixel degradation.
