Hello, my girlfriend owns a 2008 Dodge Caliber 2.0 and her red security light and TPMS start flashing after about 30 minutes of driving. She does not have TPMS installed anymore so it isn't tire inflation. I am here because it seems that it is not only the calibers that have this problem, but many different FCA models. I am wondering what I can do to fix this problem. Thank you.
