CakePHP 3 not saving hasOne associations

I have two models - Cars and CarOptions

Cars hasOne CarOptions

If the user were to edit Cars - they can also set some CarOptions and save

Everything related to Cars saves just fine, but CarOptions does not save. If I were to debug the Car object just before save - I see the following

Car: {
    "id": 3,
    "name": "Ford Mustang",
    "description": "some description",
    "city": "San Francisco",
    "state": "California",
    "country": "USA",
    "created": "2015-08-14T12:20:14-0500",
    "CarOptions": {
        "manual_transmission": "N"
    }
}

My code to save is as below

$car = $this->Cars->findByName('Ford Mustang')->first();
$car = $this->Cars->patchEntity($car, $this->request->data);
$carOptions = $this->Cars->CarOptions->newEntity();
$carOptions->manual_transmission = 'N';
$car->CarOptions = $carOptions;
$this->Cars->save($car);

However the CarOptions record is not created or edited. What am I missing?

You're not following the conventions properly, see

Cookbook > Database Access & ORM > Saving Data > Saving HasOne Associations

When saving hasOne associations, the ORM expects a single nested entity at the singular, underscored version of the association name. [...]

So for an association named CarOptions, the property to use should be car_option.

Also note that if you want to let the user choose the option and its value, hard coding it like you're doing it isn't really the way to go, instead pass it properly in the request data, and let the marshaller do the "to entity" conversion when patching the entity.
