Call to undefined method App\Models\Car::setCreatedAt() - Laravel

I am using latest Laravel. I have a model Car - id | name | * timestamp columns:

namespace App\Models;
use Illuminate\Database\Eloquent\Model;

class Car extends Model{
    protected $fillable = [
        'name'
    ];
}

Cars migration:

public function up()
{
    Schema::create('cars', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->integer('name')->nullable();
        $table->timestamps();
    });

I am trying to save new row in cars table in the controller:

    $car = new Car();
    $car->name = 'example';
    $car->save();

, but for $car->save(), I am getting this error:

Call to undefined method App\Models\Car::setCreatedAt()
