Try this:
http://php.net/phpinfo

Code:

<?php phpinfo(); ?>

Stick that in a file, load it in your browser and it will give you information about the PHP configuration and modules.

I find it more likely that the issue revolves around your input and variable management. I would run some debug tests to ensure the variable is being passed through as you expect.

Try putting this after your $vehicle=$this->input->post('vehicle');

Code:

<?php
echo '<pre>';
var_dump($vehicle);
echo '</pre>';
?&gt;

Use that same snippet right before you set your session data also. Make sure they both match the values that you expect.
