At around 63,000 miles, on my way to work, I suddenly had the TPMS light come on- not the low are pressure symbol- then it went off, then it cam eon for just a few seconds, then went off. What is that about? Thx

tps resets after air pressure is corrected but these links or read owners manual should assist How to reset service light in Citroen C4 Tyre Under Inflation Warning light Citroen C4 Picasso TPMS How to Reset Low Tyre Pressure Light TPMS

On some vehicles, you reset the TPMS warning ligh after you have inflated tyres by pressing a button or switch on the instrument panel. On other vehicles, the TPMS system will automatically reset itself and turn the TPMS warning light off after the vehicle has been driven a few miles after re-inflating the tyres.

I means your tire pressure is low

No car defect - there is a normal amount of wear on your tires after 10K miles, and
one (or more) of the tires are starting to leak air just a little bit - which after 1.5 years and
10K miles is entirely expected.
What's happening is that the TPMS (Tire Pressure Management System) sensors (one in each tire)
are sending info to the car's computer telling it that there is low air in at least one tire.
To the TPMS, "low air" means a drop in air pressure of just a few percent (set by the
manufacturer). A drop in pressure in just one tire will light the dashboard light.
The spare (temporary) tire is not monitored by the TPMS, and typically carries a pressure
of 60 PSI.
According to http://www.safercar.gov (NHTSA), a normal tire will lose as much as 1.5 PSI
per month as air escapes the tire and rim naturally.
The 2009 Toyota Venza utilizes the "direct" TPMS system (as opposed to the indirect), which is
explained by the Wikipedia article at http://en.wikipedia.org/wiki/TPMS

If you or dealer suspect the TPMS sensor(s) in one or more tires, they can be purchased on the aftermarket from sites like www.rockauto.com, www.carpartsdiscount.com, et.al. After the new TPMS sensor(s) are installed,
you (or your garage),must re-teach the TPMS system its new sensors using the following procedure: (1) let the car sit stationary on its wheels (not lifted) for at least 20 minutes, then
test drive the car for at least 10 minutes at a continuous speed of 15 MPH or greater. During the
test drive, the TPMS dashboard light should go out.

All you have to do to reset the TPMS light is make sure all your tires are set around 35-38 psi then drive it a a couple miles and the light will turn off. If it is blinking then you have a sensor issue and you will have to take it to the dealer. The tire pressure warning light is yellow not red."Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow"

The little horse shoe-looking looking thing is actually supposed to be a cross-section of a tire. That would be your Tire Pressure Monitoring System (TPMS) trying to tell you to check the pressure in your tires because it has determined that one or more of them are low.

This is covered in the Owner's Manual.
If you don't have an Owner's Manual for your Hyundai, you can get one HERE

This (!) symbol is your TIRE PRESSURE MONITORING SYSTEM (TPMS) warning light.
The manual has this to say about it:
This system monitors tire pressure. if the low tire pressure warning light illuminates, check the tire pressure in all four tires. Adjust the low tire pressure to the recommended cold tire pressure shown on the Tire and Loading information label located in the driver's door opening. After tire pressures are adjusted, the vehicle will need to be driven at speeds above 16 MPH (25 km/h) to activate the TPMS and turn off the low tire pressure warning light.

If your TPMS light is lit solid, air your tires to proper pressure (32-35psi) then drive 1/4 mile and it will reset itself.

If your tire pressure light is FLASHING, you have a fault in the TPMS system and require a trip to a shop to find out what is wrong.

It is the Tire Pressure Mounted System (TPMS). It monitors the air pressure in your tires. If it is on, you have low tire pressure...or like me, it's just a faulty indicator. Mine came on, but I don't even have TPMS on my vehicle.

Same thing happened to my 2006 T&C when the weather turned cold. I found that the recommended tire pressure was 36 lbs/sq. in. When I inflated all 4 tires to this pressure, the light went out after driving a few miles.
