i got my son this car for his birthday 2 years ago it still is in great shape i took it out for him to drive around this morning last night i charged the battery but the red light never shut off and the battery pack got hot but the car isn't working at all now no sign of power at all could this just be the battery pack? anyone have this kinda car and have this happen? my son is so upset he loves this car n im trying to figure out if i need just a new battery or need to take the car in itself to be looked at or if its just a waist n buy him a new one for his birthday.
