NHTSA Complaint #11341225 — 2015 KIA OPTIMA

I WAS DRIVING AND OUT OF NOWHERE THE CAR STARTED TO BOG DOWN AND THE CHECK ENGINE LIGHT CAME ON. IT CONTINUED TO DO IT EVERY FEW SECONDS AND WAS GETTING WORSE THE WHOLE WAY TO THE SHOP, WHICH WAS THE CLOSEST ONE I COULD FIND AS SOON AS IT STARTED DOING IT. THE SHOP RAN THE ERROR CODE AND GOT A KNOCK SENSOR ERROR. I HAD KIA COME PICK IT UP AND TAKE IT TO THE SHOP. THE SHOP PERFORMED A BEARING CLEARANCE CHECK AND THE VEHICLE DID NOT PASS SO THEY REPLACED THE ENGINE AND INTAKE MANIFOLD DUE TO "CATASTROPHIC FAILURE". WHILE REPLACING THE ENGINE THEY FOUND THE TURBO HAD PLAY AND SO THEY INSTALLED A NEW TURBO ASSEMBLY. AFTER ENGINE REPLACEMENT THEY FOUND THE STARTER SEIZED, THEY REPLACED THE STARTER. AFTER ENGINE REPLACEMENT THEY PERFORMED THE ECU UPDATE AND RESET ADAPTIVE VALUES, THEN PERFORMED WIRING SIGNAL INTERFERENCE CHECK WHICH STARTED OK. IMMEDIATELY AFTER GETTING THE VEHICLE BACK FROM THE SHOP I NOTICED A LOUD NOISE COMING FROM FRONT DRIVER WHEEL AREA. SHOP ENDED UP REPLACING CALIPER AND WHEEL BEARINGS ALONG WITH NEEDING AN ALIGNMENT. ALL HAPPENED AROUND 58K MILES. LUCKILY STILL UNDER WARRANTY. SHOP SAID IT WAS JUST A BAD ENGINE. NOTHING I COULD OF DONE COULD OF CAUSED IT.
