Ok so I have had my car only 30 - 40 days. 2005 Shinka RX-8, my TPMS light has come on. It does not stay on all the time though It will randomly just turn off after driving fora little while or it will just not come on and then turn on after starting to drive. I don't know why this is happening.

I have not changed tires. ( I have taken them off to fix my Auto Headlight monitoring light... donno if that could have done anything.)

Also None of the tires seem to be low in air.

Any suggestion on what might be the problem?

 

You need to check the pressure. You can't go by "seem to". Look in your manual and read up on it. If you are too low or too high the lite will come on. Most people run 32-34psi.

 

As Old Rotor said. Check your air pressure. Chances are your Air Pressure is a little low in one tire. Cold weather also plays a part in the TPMS. Cold in the morning, light on. Warm in the afternoon TPMS off.

 

thanks guys lol, so far it seems like it worked... Simple solution sorry for the stupid question.
