Has happened 10+ times in the last few months. Had the service dept look at once already-they just reset the tire pressures and now it is happening again.

The tires look fine and pressure is right.

It's going in tomorrow again but I just wanted to see if anyone else had any issues like this.

Check the manual and reset it if you haven't tried that yet. You should reset the monitor each time you change the pressure.

The tech did it also. took the car for a ride to "test it."

I've had the flat-tire monitor falsely trigger several times, but it would stay on indefinitely until I had it reset at the dealership... Is that what'd happening to you? Each time it went off, I'd check the pressures and confirm that they were normal, and I'd try to reset it exactly per manual without luck. After it went off for the third time, the dealership opted to replace a sensor -- I'm pretty sure I have the work order at home; I'll try to post the details. Unfortunately it *did* go off again, after this... and I *did* have to get them to reset it.

The only thing they mentioned this last time was that you have to reset the TPM with your seatbelt on.. I didn't know that, and I'm not sure why it's designed like that, but I haven't had the occasion to test it out since.

This whole TPM thing has been more of an INconvenience than a convenience, but considering the problems other people are having, I'm willing to suck this one up. ;)

happening for about a month. It goes off very regulary. I know my presure is good. I checked them cold in the morning before i leave for work, and when the TPM goes off I pulled over to check them warm. It just keeps going off and I just keep resetting it.

Have not taken it in to the dealership. If I do take it to the dealerhip they will just want to test drive it till the sensor goes off probably. F-That.

I've had mine go off a 3 times so far and every time i've had a flat tire. although it didn't look like it from just looking at it with a nakid eye. maybe have a professional take care of it.

I have been following this procedure for 16K miles without any problems at all.

1. Check air in tires and set to the correct cold not drive car after checking/setting tire pressure until you perform the following:

2. Turn key to position #2 and start car. Put transmission in 0/neutral with parking brake on.....hold tire pressure monitor button down until dash light comes on (6 seconds).....continue holding button down until dash light goes off (8 seconds).....release car immediately for several miles to allow computer to relearn new tire pressure.

DO NOT reset tire monitor again unless you first check air in tires and set to correct cold pressure.
