I have a 2004 Cayenne S. Almost 80K miles. Been great. Basically no problems.

The other day, I'm driving along and the sun roof starts opening and closing on its own (popping up). It was moving like I was pushing the button. I pushed the button and it seemed to kind of reset and I haven't seen that problem since.

The past couple of days, I go to turn the ignition and it flashes the 'battery' warning (red battery light) but starts. I noted that the clock was back to 12--lost its time. But, it doesn't seem to have low battery power. It starts and the lights are strong, etc. But it was like the electrical system had reset or something.

This evening, I come out of a store. Turn the key and it won't start. Like the battery is 'almost' dead. Tried it twice and same thing. Then I tried one more time and it started like 'normal'--plenty of battery power.

Any help appreciated.

Thank you
