What owners wrote

The 2004 rx8 has internal seals fail prematurely. This causes the engine to "blow" by a loss of compression in one of the two rotor chambers. The problem being the car with still run with half power. I continued to drive to find help off the highway. The rotor that is not working is dumping gas into the catalytic converter. By the time I parked, I could smell burning fiber and plastic and the exhaust shot out several large chunks of red hot ceramic material.
