TPMS Warning Light
Kia Vehicle
Severity: ModerateWhat Does This Error Mean?
The Kia TPMS (Tyre Pressure Monitoring System) warning light means at least one tyre is significantly under-inflated. Kia's system triggers the warning when any tyre drops 25% or more below the recommended pressure. Inflate all four tyres to the correct pressure shown on the sticker inside the driver's door jamb — not the number on the tyre sidewall.
Affected Models
- Kia Sportage
- Kia Sorento
- Kia Forte
- Kia Soul
- Kia Seltos
- Kia Telluride
- Kia EV6
- Kia Carnival
- Kia Niro
Common Causes
- One or more tyres losing pressure gradually (slow puncture or natural seepage)
- Cold weather — tyre pressure drops approximately 1 PSI per 10 degrees F temperature drop
- A nail, screw, or sharp object causing a slow puncture
- TPMS sensor battery dead — sensor stops transmitting, module flags the tyre as unresponsive
- TPMS sensor damaged after a tyre change — sensor dislodged or broken by the tyre machine
How to Fix It
-
Check tyre pressure on all four tyres with a gauge.
Find the correct pressure on the sticker inside the driver's door jamb — typically 32-36 PSI for most Kia models. Do not use the number moulded into the tyre sidewall — that is the maximum pressure, not the recommended pressure.
-
Inflate any under-inflated tyres to the correct pressure.
Check cold (before driving more than a mile). Warm tyres read 4-6 PSI higher than their actual cold pressure.
-
Drive for 10-20 minutes at speeds above 25 mph.
Kia's TPMS sensors transmit pressure readings while driving. The warning light should go off automatically once all four sensors report correct pressure.
-
If the light stays on after inflating, inspect for a nail or puncture.
Spray soapy water around each tyre's tread and sidewall. Bubbles indicate where air is escaping. A nail or screw often causes a slow leak that does not go flat immediately.
-
If the light flashes for 60-90 seconds then stays solid, a TPMS sensor has failed.
A flashing then solid TPMS light means one sensor is not communicating. Sensor replacement is required — this is a dealer or tyre shop repair.
Frequently Asked Questions
Do I need to reset the TPMS after inflating my Kia tyres?
Usually no — Kia TPMS resets itself automatically once it detects all sensors reporting correct pressure. On some older Kia models, you may need to hold a TPMS reset button under the steering column for 3-5 seconds after inflating. Check your owner's manual for your specific model year.
How much does a Kia TPMS sensor replacement cost?
A single Kia TPMS sensor typically costs 50-100 USD for the part. With installation at a dealer or tyre shop (which requires a tyre dismount and remount), expect 80-150 USD per sensor total. All four sensors need to be relearned after replacement.
Can cold weather cause the Kia TPMS light to come on?
Yes — this is very common in winter. For every 10 degrees Fahrenheit the temperature drops, tyre pressure decreases by about 1 PSI. If your tyres were at the minimum acceptable pressure in autumn, they will be under the threshold in winter cold. Inflate to the upper end of the recommended range in autumn to prevent winter TPMS warnings.
