Your Hyundai Sonata’s TPMS light can feel urgent, especially when you already checked the tires. In many Sonata models, the Tire Pressure Monitoring System (TPMS) reset button sits under the steering wheel or near the lower dash, but the exact spot can vary by model year. Before you press it, check every tire with a gauge and inflate each one to the pressure listed on the driver-side door placard. This guide shows you where to look, how to reset the light, and what to do if the warning stays on.
Quick Answer
Look for the Hyundai Sonata TPMS reset button under the steering wheel, near the lower dash, or close to the pedal area. Inflate all tires first, then turn the ignition to ON and hold the reset button until the TPMS light blinks three times. Start the engine and drive for several minutes so the system can relearn the tire pressure readings.

Why TPMS Matters in Your Hyundai Sonata
The Tire Pressure Monitoring System (TPMS) in your Hyundai Sonata helps you spot low tire pressure before it creates a safety issue. Proper tire pressure can improve handling, help tires wear more evenly, and support better fuel economy.
Most modern Hyundai Sonata models use sensors that monitor tire pressure and trigger a dashboard warning when pressure drops too low. A solid TPMS warning light usually points to low tire pressure. A blinking light often points to a system fault, such as a weak sensor battery or sensor communication issue.
Check your tire pressure at least once a month and before long trips. You should also check it when the weather changes because tire pressure can drop as outside temperatures fall.
Common TPMS Issues in Your Hyundai
Your Hyundai TPMS can alert you for several reasons. Some issues involve tire pressure, while others involve the sensors or valve stems.
TPMS issues in your Hyundai can affect tire performance; knowing them helps ensure safety and optimal function.
- Low tire pressure: One or more tires may need air.
- Slow leaks: A puncture, damaged valve stem, or tire bead leak can trigger the warning light.
- Temperature changes: Cold weather can lower tire pressure enough to turn on the TPMS light.
- Sensor problems: A weak battery, corrosion, or sensor damage can cause false or repeated alerts.
If the TPMS light turns on, check all four tires and the spare if your Sonata has a monitored spare tire. Do not rely on the warning light alone to judge tire safety.
Before You Reset the TPMS
Plan for about 5 to 25 minutes to reset the TPMS and let the system update. You will need a tire pressure gauge and an air source if one or more tires need air.
- Park your Sonata on a level surface.
- Let the tires cool before you check pressure.
- Find the recommended PSI on the driver-side door placard.
- Inflate each tire to the listed pressure.
- Inspect each tire for visible damage, nails, or low tread.
Warning: Do not reset the TPMS to hide a warning before you confirm that every tire has safe pressure.
