On a somewhat related thought, my TPMS threw up an error once. Not a "low pressure" alert, but something to the effect that service was required. It only happened once in a torrential downpour and cleared itself. I assumed RF interference due to all the water. I mentioned it to service and they seemed to know about an issue having to do with the receiver in the car. However, when I got my car back, they said it was because the tire pressure was too low, and adjusted the pressure in my tires. I dunno about that because I do check my pressure regularly and had never once received a "low pressure" warning. In any event, it has not given me any trouble since.
I had something similar happen to me twice. Both times I had been on an extended drive on a hot day and the car was full. Once I had three adults and two dogs for passenger and the other was when I was moving my son to a university and I had two passengers and a car full of his things. Both times the error cleared itself up after letting the car sit so I assume that the pressure in the tires had risen too high because of the excess heat and weight.
