Hyundai's owner's manual splits service into Normal and Severe schedules. Most US drivers qualify as Severe due to short trips, extreme temperatures, or stop-and-go traffic. Hyundai Assurance covers the first 3 years / 36,000 miles of complimentary maintenance on new vehicles. The Theta II 2.0L and 2.4L engines (2011-2019) are subject to TSBs around oil consumption — strict adherence to oil intervals matters.

Dealer
~$180–$200

Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Hyundai Long-Life Coolant (pink): first change at 60,000 miles, then every 30,000. Do not substitute green or orange coolant — it damages the cylinder head gasket on GDI engines.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Estimated cost — typical U.S. ranges
Dealer
~$60–$95

Estimated cost — typical U.S. ranges
Dealer
~$195–$235
Shop
~$135–$165
DIY
