I have a '05 ION with 9000km on it. This has happened to me twice in two weeks. The first time it happened, the car just stopped running when I put it in park and the battery light came on. I started it up again with no problems and drove it all this week. Well, a couple days ago it happened again, but this time I noticed that the RPMs, which usually over around 700 when in park, hit 500 and just kept dropping to 0, and then my car shut off. The battery light also came on again. Again, the car started up with no problems. Also, about 25% of the time when I do put it in park, the RPM briefly dip to 500 RPM for about a second or two. At that time, the car sort of hesitates and headlights dim but then the RPMs kick back up to 750 and lights strengthen again. This only happens on accasion. I'm puzzled as to why this is happening. It just so happens that both times I had just filled up my gas tank just before, but I doubt that'd be it. I called the service dept at my local Saturn dealer and they've never heard of it, but I'm bringing it in to be checked in a few days. However, it's possible they might not be able to pull the code for it, and will just hand me back my car, saying they couldn't duplicate the problem. Any ideas?
