Hyundai Sonata service: key facts

Routine service items

These are the items covered in a standard service. Most garages include oil, oil filter and a basic inspection. The rest are typically checked or replaced on a schedule.

Service itemIntervalTypical cost
Engine oil and filter
Manufacturer specifies 10,000 miles or 12 months.
EF, NF
 10,000 miles or 1 year
£80–£120
Dealer: £150–£200
Air filter
Replace every 20,000 miles or 2 years. Check more frequently in dusty conditions. Clogged filter reduces performance and increases fuel consumption.
EF, NF
 20,000 miles or 2 years
£20–£35
Dealer: £35–£60
Cabin pollen filter
Replace annually or every 20,000 miles. Blocked filter reduces air flow and can cause HVAC system strain. Check if air conditioning performance deteriorates.

Periodic maintenance

Items that don't need doing at every service but should be on your radar at the right mileage or age.

Service itemIntervalTypical cost
Spark plugs
Replace every 30,000 miles for conventional plugs. Iridium plugs may last longer. Worn plugs cause misfiring, poor fuel economy, and emission test failures.
EF, NF
 30,000 miles or 3 years
£60–£100
Dealer: £100–£160
Brake fluid
Replace every 2 years regardless of mileage. Brake fluid absorbs moisture over time, reducing braking performance and causing internal corrosion. Critical safety item.
EF, NF
 2 years
£50–£80
Dealer: £80–£120
Coolant flush
Replace coolant every 5 years or 60,000 miles. Use correct specification antifreeze. Degraded coolant causes corrosion and overheating. Check level regularly.
EF, NF
 60,000 miles or 5 years
£80–£120
