When I got this car, I noticed that the coolant container doesnt stay full. In fact, I have to go to walmart to by collant and fill the container every week. I noticed there is a leak as well and its spraying all over the motor and battery. Aldo after driving for hours, I'm able to open the cap to the collant container with no issues. It's not hot or anything. Not sure what's going on with this car and dint want go spend hundreds of dollars just for someone to look at it.
