🔧 Maintenance

Oil Change Interval:

Typically 5,000 - 7,500 miles or 6-12 months, whichever comes first (refer to manual for exact specification)

Air Filter Replacement:

Every 15,000 - 30,000 miles or as needed based on operating conditions

Spark Plug Replacement:

Every 30,000 - 60,000 miles (depending on spark plug type - standard or platinum)

Timing Belt Replacement:

Critical interval, typically 60,000 - 90,000 miles or 5-7 years. Failure can cause catastrophic engine damage.

Engine Oil Type:

API SJ or SL, SAE 10W-30 or 5W-30 (viscosity may vary based on climate, refer to manual)

Engine Reliability:

Can be prone to minor oil leaks, ignition coil issues, and potentially early wear on valve stem seals if maintenance is neglected.

Transmission Reliability:

Manual transmissions are generally robust. Automatic transmissions may develop issues with shifting or torque converter if not serviced regularly.

Electrical System:

Aging wiring harnesses, intermittent electrical gremlins, and issues with door lock actuators or power window motors are common with age.

Suspension And Steering:

Worn ball joints, tie rod ends, and bushings can lead to vague steering and poor handling. Power steering pumps can also be a failure point.

Corrosion:

Body rust, especially around wheel arches, rocker panels, and the subframe, is a significant concern in areas with road salt.
