I just purchased this vehicle and have been loving every moment of it. Something ive noticed over the past couple of weeks is the check tire pressure light will go on for a while than it will go off. Sometimes it will stay on for 2-3 days at a time. Being in west texas I figured it could be that it was too low in the mornings when its only 65-75 degrees and once it warms up it will be up to the correct pressure. Primarily based on after the day drove on and it got to 105 or so or I was driving it would go away. Well the light still kept coming on even when the temperature was right and I was driving it. I checked all four and they are within operating range. So I took it into the shop and had nitrogen placed in them. When they did the light would not go off. They said it would in a few days and it didnt. So I took it in and they couldnt find anything wrong. They reset the sensor and changed some of the programming and it stayed off for two three weeks. And now its back again. Its under warranty so Im thinking that if its a faulty sensor will it be covered both labor and parts and where can I go to find out how much that would be?

I hope Im not giving you guys newbie questions but Ive done alot of research before buying this car and did alot of things before I came here to ask you guys what you think.

 

Seeing as you just got the car and know little about the history, it may be possible that one of the tires had-has a repair sealer (fix-a-flat) in it at one point in time. That can mess up the sensor. Might be worth a check.
