This happened each of the 5-6 times that I tried to start it. I let it set in my garage overnight and it did start the next day, although the automatic transmission was in the "limp home" mode. The transmission went into it's usual status when I shut the engine off and restarted (no problem) as instructed by the owner's manual. Since this incident, the car has started normally dozens of times. I checked the battery and it's indicator shows an adequate charge. The "check engine"/ MIL is not illuminated.
Does anyone have an opinion as to what caused this failure to start? Will the OBD2 system have a record of this incident? I don't yet have such a tool but will probably get one soon. I'd like to know what happened and if a future occurance will leave me stranded away from home.

If I'd left the car's lights on I would have noticed it. And when I tried to start the car, the headlight switch was in the off position. The car also has a warning chime that sounds if I exit the car with the ignition off and the lights on. I too thought that the car was acting like low battery, but that wasn't the case. When it wouldn't start, I switched the headlights on to see how bright they would appear; they appeared normal. If it happens again, I'll check the battery with my battery (load) tester.
Do you think the OBD2 has a record of this incident? I'm thinking about getting Autoenginuity's OBD2scan tool and it's associated pc software. This tool is a bit more expensive that some other scan tools. Is it worth the extra cost or is this program useless?
