Tire pressure sensor

Well most tire shops are only filling the tire to about 32 psi due to new policies but most car size tires need 35psi. the sensor is set to go off at about 30-31 psi so do yourself a favor and put 35psi in the tires like it says on the tire side wall and it will stop telling you to.

Cool weather will lower the tire pressure.

Check your tire pressure. I run all mine at 36 psi and have no issues. In my opinion the TPMS is one of the greatest things they ever put on a vehicle. No more ruined tires from running them low on air.

my TPMS has been going off almost since I bought the car in 2008. I would ask the dealership to fix it and they just reset it over and over until the warranty went out then told me it was a bad sensor and wanted over $200 to fix it. Over the 5 year warranty I had it looked at least a dozen times but they didn't want to do anything about it until out of warranty so they could charge me.

Bring all records of you taking it to them and take it to the dealership owner.
