You can be charged if it can be shown that you loaned the car to someone who you knew, or had some reasonable basis or grounds to believe, would use it for criminal acts: in that case, you assisted in the acts by providing them a car and can be charged as an accomplice. If you had no idea what they were going to do, you did not commit a crime and should not be charged--or even if initially charged (because the authorities are not sure of your role) would not be convicted if there is no evidence of your collusion.Also, be aware:If you loaned the car to someone without a valid license, that can result in most states in a fine and suspension of your own license.If there was anything of yours criminal in the car (e.g. drugs or paraphrenalia) and it was found, you could be charged for those things.
