Why the light loves cold mornings, when it means a real leak, and why 'just add air' sometimes isn't enough.
The little horseshoe-shaped light with an exclamation point is your Tire Pressure Monitoring System (TPMS), and it confuses a lot of drivers. Here's what it's actually telling you.
Why it loves cold mornings
Air contracts as it cools, so a cold snap can drop your tire pressure enough to trip the light, even with no leak. Tire pressure falls roughly 1 PSI for every 10°F drop, which is why the light so often appears on the first cold morning of the season. Topping the tires back up to the correct pressure usually clears it.
When it means a real problem
If the light keeps coming back after you've properly inflated the tires, you likely have a slow leak, a nail, a bad valve stem, or a wheel that isn't sealing. And if the light flashes for a bit before staying on, that often points to a failing TPMS sensor (the sensors have small batteries that eventually die, usually after several years).
Why correct pressure matters
Underinflated tires wear out faster and unevenly
They hurt fuel economy
They can overheat at highway speed, a blowout risk
Correct pressure gives you the best grip and braking
Don't just ignore it
Taping over the light isn't a fix. At TAB Motors we diagnose the TPMS, find any leak, set your pressures to spec, and service sensors when needed, so the light goes off and stays off. Call (703) 243-3080.
