The water never gets to 32 F because the car and water retain heat, which takes time to dissipate. The night is too short.

Obviously the water in the bottle has not reached the freezing point. Just because the air around it has reached 32 degrees does not imply the water is at 32 degrees. Also even when the water has reached 32 degrees there must be a change of state before it can turn to ice and that takes even more heat out of the water. The water has heat capacity. Each gram of water at 32 degrees must give up 333 calories to the environment of the car before it can turn into 1 gram of ice at 32 degrees. So if you have a liter of water (1000g), 333,000 calories has to be removed from it even when the water is at 32 degrees for it to freeze and turn to ice at 32 degrees.
In food calories that would be 333 food calories.

You car retains heat and does not cool down below 32 fast enough. Let it colder and you will find a block of ice there.

probably cause it doesn't actually get below 32 in your car. It might be outside but not inside.

Leave it long enough in the perma-frost and you'll succeed
