Has anybody else experienced their Cruz jolting while at a stop light while your foot is firmly on the brake?

I bought my 13 LTZ through hertz. I was thinking that it was doing this because it was a rental but when I took it to the chevy dealer they felt "nothing out of the ordinary". If anybody has experienced this I would like to know if you were able to get a diagnosis.

 

no codes? I'm assuming all the recalls have been done?

 

Does Auto Zone still do free code checks?

I've been hearing about a lot of issues with the Cruz. You would think that Chevy would address them because that is bad publicity.
