2016 here with 9K miles on it. Had an interesting occurrence two days ago which has yet to repeat itself. The car had sat about a month while I was on vacation. Car was on trickle charge all that time. I got a text from the My Cadillac app on my phone saying the the left rear tire pressure was low and the others were low, but not as low. I checked all the pressures manually and all were within specs and half PSI of each other. I uninstalled the app and restarted it. The app still said low pressures. Then magically the next day after haviing driven the car, the app displayed all pressures were normal and agreed with the manual tire pressure gauge. I guess the electronics self corrected themselves. Has anybody ever experienced this or want to guess what caused it? Could it be from sitting unstarted for several weeks? Just curious. Any insights appreciated.
