The electrical system completely shuts down. Nothing works. Sometimes if I wait a while it will start. If it doesn't you need a tow. Last time it shut down it locked with key inside. Combination lock would not work because no electric. Had to call locksmith. As soon as he opened the door, electric came on. Had it at the dealer all day and they can't find the problem. I can't count on the car to start, it's always a doubt. Some times it will go a month or two no problem, then it does it again.
