What is wrong if your car hesitates to start for a few days and finally a few days later it won't turn over. I have an 03 XG350L never replaced the starter. How long do starters last?

Starters are normally good for at least ten years. Often they last much, much longer. BUT, they do occasionally fail sooner. Yours does not sound like a starter problem. Recharge the battery and jump start the car and get it to a competent mechanic.
