NHTSA Complaint #11486667 — 2018 KIA SOUL

My vehicle randomly started making a knocking noise. We took it to our local mechanic who stated he has seen a lot of these come from the Kia line lately. the knocking noise comes from the rods. He said the cost to get this repaired would be $4,000-$5,000, since the bottom portion of the engine would need to be replaced. This car is not driveable. We are the 2nd owners and the car only has $65,000 miles on it. We bought the car from carmax in November 2021, and they did a full investigation and found no fault with the car. The rod knock started in March 2022. We are hoping there would be a recall on this, as we see from forums, we are not alone. The check engine light did not come on at any point.
