Maintenance
|
Service Intervals
|
Oil Change:
|
Typically every 10,000-15,000 km or 1 year, whichever comes first (depending on driving conditions and oil quality).
|
Timing Belt:
|
Recommended replacement interval for most 4-cylinder engines is around 90,000-120,000 km or 5-7 years. V6 engines with timing chains have longer intervals or are designed to last the life of the engine.
|
Spark Plugs:

|
Known Issues
|
Ignition Coils:
|
Failure of ignition coils is a common issue, leading to misfires.
|
Window Regulators:
|
Plastic components in window regulators can break.
|
ABS Sensors:
|
ABS sensor failures can trigger ABS and traction control warning lights.
|
Oil Leaks:
|
Leaking valve cover gaskets and oil pan gaskets are common.
|
Cv Joints:
|
Wear on constant velocity (CV) joints can lead to clicking noises during turns.
|
Suspension Components:
|
Wear in control arm bushings and ball joints can affect handling.
|
Climate Control Actuators:
|
Blend door actuators in the HVAC system can fail, affecting temperature control.
