This just happened to me this morning. It started by my car saying there was no key..which was in car...so my daughter took the key and walked away,walked back and it started. A few hours later I go to leave,it started fine went into store came out and hour later and dead ,nothing.Then finally it said shutting down to save the battery...My husband unplugged the battery ,then after a few times it started.I took it straight to dealer it started fine,they check battery fine...I talked to service manager he said it was the key fob,use the other .Starts perfect ,go home use other key a little later takes 3 times to start.Once started it runs perfect.We updated the sync...still doing it...Any ideas? I really love this car it only has 39,000 miles on it. UGH*
