Tire pressure sensors fail without indication. The sensor registers pressure when it is actually zero. With run flat tires this causes an unsafe condition.

There is a dangerous problem with my Corvette that I believe is tied to faults in the tire pressure monitoring system. I was driving on a freeway following a left curve when I felt the brakes grab. I saw "active handling" displayed; however, there was no reason for active handling to occur (roadway was dry, was driving at posted speed limit, was not making a sudden turning maneuver). Later I saw that the car was displaying a front right tire pressure of 0 psi, but no other warnings occurred (typically, a yellow warning light goes on an car displays a low tire pressure or right front tire flat warning when this occurs). I've had ongoing problems with the tire pressure monitoring system and Chevy has attempted repair once. Usually one of the front tires will read zero psi and the aforementioned warnings will appear, and the car's active handling system will engage more easily, then a few minutes later, the car will display normal tire pressures again. In the incident I'm describing here, there was no warning that the tire pressure was being read at zero, and no indication that active handling would engage so easily. This is a definite safety hazard that could result in loss of control or a crash. I have an appointment to get the car serviced in two days.
