Hi I am having issues with the steering in my 2018 Silverado 3500 duramax. It has not happened before today. While driving straight at 40-45 km/h (25mph) on flat paved road, it feels like the steering wheel is being pulled left for a split second then returns to normal. A slight jerking or tugging and the whole truck feels very loose momentarilly then stiffens back up. It feels like it is an electrical malfunction instead of mechanical. The truck will not replicate at higher speeds. After reading other's posts, some say possibly a PSCM or ESM issue, others say an ABS or Stabilitrak issue where the left front brake is grabbing at random. I did have a blown out CV axel on the left front that I decided to finally change today after this started but it has not fixed this issue. After researching a bit more I have discovered GM had a recall for 2015 vehicles having the same issue. Can anyone help me out in diagnosing? I fear if I bring it to the dealership they will not be able to replicate and give it back to me without a fix. I have no DTC's or warning lights on so far. Here is a link to my YouTube channel and a video which clearly shows the steering wheel jerking and what I believe to be manipulated by an electronic malfunction. The section of road I'm driving on has no potholes and surface is very smooth. The truck is moving the steering wheel on its own. Thanks
