Tire Pressure Indicator on Dashboard

[sighn34]

Sportage 2020. I would want to enquire if the chilly weather from last night has caused the Tyre Pressure warning light to activate. It indicates a pressure of 31 psi on both the left side and 29 psi on both the right side. Is this a legitimate problem that requires consultation with a Kia agent?

Cold weather causes air to contract, resulting in decreased tire pressure. Inflate the tires to the appropriate pressure (35 psi) when cold to resolve the TPMS alarm.

The alarm will not deactivate until the vehicle exceeds a certain speed, which I believe is 20 mph.

We had the same issue yesterday. Last year, at the onset of winter weather. Requires a little inflation of the tires.

Likewise.
The wife reported that the triangle indicator on the dashboard and the collision warning were activated when she was driving the Proceed to work.
This is as previously stated.
All tires exhibited a decrease in psi owing to a temperature of -4, resulting in a collision warning as the tire pressure fell below the acceptable level.

Annually, I adjust the tire pressure as temperatures fall to winter levels and then modify it again when temperatures rise in late spring and early summer.
This includes monthly inspections as part of standard vehicle maintenance.

I apologise for interjecting in this discussion, but I own an 18-month-old Stonic, and since I first inflated the tires and reset the TPMS, I have not had to add air to them at any point.

I have not personally inspected the tires since then; before anybody criticises me, I have been complacently depending on the TPMS to alert me if any tire becomes underinflated. They all seem satisfactory, and I will examine them this weekend. Is it uncommon to go an extended period without needing to inflate the tires?

Tyre pressures fluctuate with environmental changes; nevertheless, if the tyres are in good condition, they often maintain their pressure within a few psi.

The tire pressure may have been replenished at the car's servicing; nevertheless, tyre pressure might fluctuate when the vehicle encounters a pothole or is curbed. Therefore, if it has not been addressed, it is less probable that your pressure is diminished.
