Car is not working

I am creating a car, and, to say the least, it does nothing. Now, I am using the old surface system simply as I don’t know how to use the new system (help with that would be appreciated). I noted that AreHingesDetected is 0, which is odd, as this and the 4 cylinders with hinges touching the block part are also all in a model. Any help with why this is happening would be appreciated.
