Model error

Hi, recently I start seeing Model error in logs. It happens rarely but I wanted to know reason.
Error saying:
ERROR - 2018-02-05 13:57:26 --> Severity: error –> Exception: /public_html/application/models/Car_model.php exists, but doesn't declare class Car_model /public_html/system/core/Loader.php 336

My Car_model.php:

PHP Code:

<?php if (!defined('BASEPATH'))  exit('No direct script access allowed');


class Car_model extends CI_Model { 


starts this way.

What might cousing this error?

Are you just loading the Model in a controller or are you auto loading it?

If it's in a controller try loading it in the controllers __constructor.

What did you Try? What did you Get? What did you Expect?

You're saying this happens intermittently? In other words, sometimes the class loads, but sometimes it won't?

I am loading it in MY_Controller.

yes Dave it happens intermittently 

PHP Code:

class MY_Controller extends CI_Controller {

    public function __construct() {

        parent::__construct();
        $this->load->model('utility_model');
        $this->load->model('blogs_model');
        $this->load->model('car_model');
}
} 


If your going to load it in the MY_Controller you might as well autoload them.

I would load them in the Controllers that use them.

What did you Try? What did you Get? What did you Expect?
