Laravel join 3 tables using Query Builder

I have a function that expects a query builder as input parameter. On the query I want all the records returned from this query:

$query = $model->newQuery()
            ->leftJoin('materials', 'products.material_id', '=', 'materials.id')
            ->leftJoin('vehicles', 'products.vehicle_id', '=', 'vehicles.id')
            ->leftJoin('parts', 'products.part_id', '=', 'parts.id')
            ->select(
                'products.id as id',
                'products.name as product_name',
                'parts.part_name as part_name',
                'materials.public_name as material',
                'vehicles.name as vehicle'
            );

Using leftJoin the function runs but returns nothing and if I replace leftJoin for join (what I think it's the right solution for this case) vsc says it's not a Query Builder and executing returns 5xx error.

$model binds to my Product model.
