While doing my first long trip last weekend, the tire warning light came on. I pulled over and looked at the tires, and all appeared to be OK, and since I didn't have a tire gauge, I went on. The light went out for awhile and then came back on; did this 2 or 3 times. When we got to our stopover point, I bought a gauge, and checked the pressure. They were all right on the money.

Anyone else ever experience this? For the rest of the trip, it came on and went off several times. It would stay on for about 15 or 20 minutes at a time, and maybe off for a couple of hours.

The day after I got it, I lost one of the valve stem caps. Could this cause the problem? I was just waiting til I took the car in for service to replace it; but if that's the cause, I'll take it in sooner.

If the tires weren't low on preassure then the light should not have come on. Not having a valve stem cap could cause this because as dumb as it sound the little caps act as tiny antenna's so that the computer can pick up on the data that the sensor is giving off.

Let me ask if by chance one of the tires that's missing the cap is on the rear? If so it might be that the computer is unable to read the sensor correctly..

There is one more thing that it could be which is related to tire temp, as you drive the air inside the tires expand a little (not much) but little, if you checked the tires right when you stopped then you could have been reading on the high side of the pressure, ever notice that it says "XX" amount of PSI COLD

You also said that it would come one for a little bit and then go back off and I'm curious if you where maybe driving at different elevations as this plays a little bit into tire pressure as well.

I work at NTB p/t and we have had a few newer Hyundais come in and the owners complain about the tire light being on and sometimes its a matter or 1-2 psi that we top it off with and the light goes off, I think these newer sensors and the programing is very sensitive. One thing I do really like is that the sensors on the new Hyundais have the rebuildable valve stems that use a little bolt the hold the valve stem to the sensor, this makes it so much easier to not break the sensors when changing tires.

I hope some of this info helps you and maybe solves ur issue.

Nope the cheap plastic caps do not act as an antenna..............
I replaced mine with a nicer metal cap and it didn't change anything. I had all 4 of the plastic caps off and no lights came on.
I believe you have a bad sensor on one of the wheels or one of the long life batteries is starting to fail

I did some testing a while back on my TPMS. First, I used a gauge known to be accurate (I work at a testing / inspection lab). Working with cold tires that sat overnight, in 70ish degree weather, all four sensors tripped the warning light at 28 psi, +/- about 1/2 psi. I have the 17" Limited wheels w/ Kumho KH-25 tires.

I had all four tires set at 34 psi (16 in. Kumho's) when I left home. After the incident (several hundred miles), they were all within 1/2 lb of each other. Part of this trip was in a bad rain storm, and I thought this might have had something to do with it. But the return trip was several days later, dry and hotter; so I guess that wasn't the cause.

Guess I'll go by the dealer and pick up another cap, when I get up that way. It was on the rear, by the way.

Since it was on the rear, could it be something as simple as a weak battery in the sensor?

I highly doubt it would be a weak battery in this short of time, I mean anything is possibly but these sensors are designed to last years and years.

While making a 400 mile trip I too got the tire warning light. We had so many Tech gears in the car using at the same time that I am convinced one of those caused problems with the RF of the sensors. We had 4 4G phones, 1 of those phones paired with the NAVI via bluetooth, 1 lap top with wireless on and connected via bluetooth to one of the 4G phones as tethering device for Web Browsing, there was also an iPod using the tethering phone. I am sure all that caused the carputer go crazy. Still I had to stop at Loves and get an air gauge just to make sure all 4s where OK on PSI. All I can tell you is that this issue is making the air gauge bussines grow..LOL.

Try with no wireless devices on the car at all. I know when we started turning off the devices it eventually stayed off, so many tech gadgets confused the computer and sensor communication. No tire light since then and that was 2 1/2 months ago, or 3,000 miles ago however you want to see it.

By the way, we ALWAYS carry our 4G androids and one of them (usually mine) always connects to the NAVI via bluetooth. We haven't seen the problem again, but our commute is usually less than 30 miles while going out during the weekend, only difference is that we don't carry the lap top and browse and the iPod and.... LOL... you get the idea.

I don't think the caps have anyhing to do with this issue.

My Tire Pressure Warning came on yesterday morning on my 2011 SE Turbo with 18" Hancook tires.
I had a 25 mile drive to work during which the car rode and handled normally.
When I got to work I didn't have time to check tire pressure, but none of the tires looked low based on a quick walk around the car and a visual check.
After work, I used the old, cheap tire gague I keep in the console and each tire was around 30 psi instead of 35psi.
I stopped at a gas station and put air in all 4 tires to inflate them back to 35psi, not worrying about the fact that the car was originally delivered with Nitrogen in the tires, and when I started the car the warning light was off.

It worked as I would want it to - warn me there's a problem before it really affects anything and turn the warning off when the cause is fixed.

While it's curious that all 4 tires were down by 5 psi and that the warning came on, I'm guessing that one of the tires was probably a little lower than my tire pressure gauge registered and that's why the warning was triggered. At any rate, I'm please it worked as it did and still love the car - no pull issues.

I have had numerous problems with the TPMS on my '11 limited. I have an aftermarket Garmin nuvi and dealer told me there was a service bulletin reporting of interference between the gps and tpms. Don't know if anyone else has heard of this problem. If it was my truck I'd put a piece of tape over the light and be on down the road. lol
