NHTSA Complaint #11659902 — 2016 KIA SOUL

My 2016 Kia soul had the engine white come on. I took it to have the computer read what the problem was. It came back engine knock sensor. I was told there was a recall on this and I needed to take it to an authorized Kia dealer. I took this to an authorized Kia dealer who told me that that was a faulty check engine light there was nothing wrong with the sensor, but my pistons were bad and I needed a new engine. Well, when I read further into the recall, it specifically said that this check engine sensor issue could affect the engine. My car just hit 100,000 miles. I had regular service. I now have a Kia who is sitting in front of my house not being able to be run. I truly feel that there is an issue that was not addressed when it was checked the check engine light indicated faulty knock sensor. This recall connected that there may be issues with the motor if this were the problem. I feel like I’m being taken advantage of. I am currently without any transportation and cannot get any help. Is there anything you can do to help me?
