First thing. Please use code blocks for your code. Makes it much easier to read. like this

Controller
Code:
code here...
Model
Code:
code here...
View
Code:
code here...

Now on to your question. From the looks of you code am I correct in saying that for each category displayed the result is all the car names from the last category.

Category 1
------------
Car_name_1_from_Category_3
Car_name_2_from_Category_3
Car_name_3_from_Category_3

Category 2
------------
Car_name_1_from_Category_3
Car_name_2_from_Category_3
Car_name_3_from_Category_3

Category 3
------------
Car_name_1_from_Category_3
Car_name_2_from_Category_3
Car_name_3_from_Category_3

If I am correct, it is because of this

Code:
foreach($fleets as $row)
{
$cid = $row->category_id;
$this->data['listefleets'] = $this->Fleets_model->list_fleets($cid);
}

from this code it looks like every time you loop you are overwriting $this->data['listefleets'] so by the time you call the view your $this->data['listefleets'] only has the info from the last loop

Try:

Code:
foreach($fleets as $row)
{
     $cid = $row->category_id;
     $listefleets[] = $this->Fleets_model->list_fleets($cid);
}

$this->data["listefleets"] = $listefleets;

Use <pre>&lt;?php print_r($variable);?&gt;</pre> to see what you've to render (an array).

Show your databse table structure, that could be the problem!

When dealing with categories any sub-categories need to have
a parent_id pointing to the main category.
