NHTSA Complaint #11585700 — 2015 KIA OPTIMA

Not sure what the exact problem is and my mechanic cannot figure out either, I had the car a little over a year purchased from carvana! First few months the brakes started messing up got caught in the rain ran into a trash can left minor scartches but nothing was wrong internally. September got side swiped on the highway not a reportable accident but I had to change whatever held the wheel literally everything that holds the right wheel had to be changed and after that incident a sensor came off, traction with wheels off but still drivable, about 3 days ago the engine just started making a cracking sound mechanic said it was some sensors he changed both and still making the weird noise, only had the car for a year and my mechanic cannot pinpoint the problem and suspects some type of engine issue which idk if it’s a recall on Kia optima’s or not because I don’t drive crazy!
