I have had the exact same problem two times now - it is scheduled to go to the dealer tomorrow - but they already told me if they cannot replicate problem they can't do anything????? The first time it happened I played around 15 - 20 minutes to try to get the car turned off - including putting the key in - off course that didn't work. Once I finally got it off - I came back to leave about 20 minutes later and had no dash lights either. Yes - I am sure I didn't have the dimmer turned down - in fact after driving about 20 minutes - they automatically came on by them selfs - magic! Yesterday when I started the car in the morning I had no dash lights again - when I got to my destination the car would not turn off - ended up playing with it for about 10 minutes. Also, last week I was sitting in the car (engine not running) - just listening to the radio waiting to pick my daughter up - when I pushed the power button the car came on in Neutral - couldn't shift to drive or reverse - had to power off completely and restart. Any ideas - again my dealer said if the car is not doing this when I take it in tomorrow they cannot do anything - so another words wasted trip because when I get there it may be just fine and then they don't know what to check.
