Q: TPMS light comes on frequently, but false alarms

The Tire Pressure Monitoring System light has been frequently turning on while driving. Several times I have been to the service department and every time I am told that they can not find any problem. I learned that there is a known defect of the TPMS light going on when something is being charged. Since this would mean it’s not the service departments problem, I only charge when necessary. However the TPMS light goes on even when nothing is in the charger. According to the manual, when it goes on I am supposed to go immediately to the service department. Since mine is going on so frequently, it is impossible to take it in every time and I work full time.

Everytime it goes on, my family and I feel so stressed because we hope it’s a false alarm like the other times. And each time, sure enough it has been false alarms, but this is causing too much stress! There is no pattern to this - no rhyme or reason as to why or when it will light up. What worries me is that I’ve gotten to the point where I assume it is a false alarm and what if one time it happens and it is a Real Warning! I have no confidence in my car, constantly stressed, waiting for something to go wrong. In your expertise, what is causing this and what will fix it?
