I have not been able to correlate this with anything, time of day, temperature, city or highway driving, etc. It will sometimes be that way when I start and stay that way until I turn the car off and restart it and at other times it will be OK when I start the car and then all of a sudden I will get the TPMS error display that will usually stay on until I turn the car off and restart it. Sometimes it will spontaneously clear itself and read the tire pressures accurately. All the while this is occuring the tire pressures are normal, 35 psi. As usual when I ask my dealer about it I get the usual response "I dunno"!

Anybody got any ideas (other than going to another dealer, which I am strongly considering)?

Go to a dealer. You have a bad sensor.
