I have 37 PSI cold, I drove to Austin and back, about 200 mile round trip, air temp was 85 and sunny. My tire pressure light came on, I pulled over and looked at tires they were fine, checked pressure all were 40PSI. it stayed on for rest of trip, about 40 minutes. I got home, turned off car, came back out 20 minutes later and went to store light did not come on. I has not come on again. Any ideas?
I've had that happen, with our 2010. I pulled into a gas station, checked pressures, they were all around 35~36, the usual pressure. For the heck of it I bumped them all close to 40. The light went out after a few minutes driving. The next day I took them back down to 35~36, and the light stayed off. Short version: gremlins.
