The TPMS light usually means a tire is low on air. Check pressure and inflate to the door-jamb spec. Most causes are temperature change or slow leaks.
Every modern vehicle sold in the US since 2008 has tire pressure sensors that warn you when any tire drops 25 percent below the manufacturer's recommended spec. The most common causes are temperature change (cold weather drops pressure about 1 PSI for every 10 degrees F), slow leaks from valve stems or small punctures, and wheel-rim corrosion that lets air seep around the bead seal. Less often, a TPMS sensor battery has died. Sensor batteries typically last 5 to 10 years.
Yes for short distances. Check tire pressure within 10 to 20 minutes of seeing the light. Underinflated tires generate excess heat, accelerate sidewall flexing wear, and reduce handling and braking response. Severely underinflated tires under 20 PSI can separate from the rim during a hard turn and blow out from internal heat buildup at highway speeds.
Check pressure at all four tires and inflate any that are below the door-jamb sticker spec. Temperature drop is the most common cause.

See tire repair (plug or patch) pricesAll tires are properly inflated but the light stays on after driving 10 or more minutes. The sensor battery has died, typical at 5 to 10 years old.

Document what you find. Hand the notes to the shop when you check in. Technicians charge for time, not for guessing, so anything that narrows the diagnostic search saves you money.
Most shops follow a three-step diagnostic process for symptom-driven complaints: replicate, scan, and inspect. Replicate means the technician drives the vehicle until the symptom appears, confirming it is reproducible. Scan means hooking up an OBD-II scanner to pull stored fault codes and live sensor data. Inspect means putting the vehicle on a lift and checking the components most associated with the symptom and any codes found.
Diagnostic fees in Florida and Georgia run $80 to $150 for the basic process and up to $250 for more involved drivetrain or electrical issues. Many shops apply the diagnostic fee toward the cost of the repair if you authorize the work the same day. Ask whether the shop rolls the diagnostic into the repair before you commit.
