I was driving the car when all of a sudden all the messages came on - TPS, air bag system, traction light, engine light stayed on. I had no gas gauge, no TPS, no speedometer, no turn signal, no flasher, nothing . All gauges went to zero. I came home, shut the car off with the usual shift to park message again. I waited a few minutes, then started the car up and drove around the block and all the messages were gone as if nothing was wrong. I could've been in a serious accident with no warning system to let other drivers know I was in trouble.,
