NHTSA Complaint #11164285 — 2013 CHEVROLET SONIC

AIR INTAKE SYSTEM. NOT LONG AFTER WE BOUGHT THE CAR THE CHECK ENGINE LIGHT CAME ON READING A CODE PH171. WE WERE TOLD IT WAS A KNOCK SENSOR WHICH WE REPLACED AND IT DIDN'T FIX THE PROBLEM, AFTER WE WERE TOLD IT WAS THE AIR INTAKE HOSE, CHECKED IT AND IT LOOKS LIKE IT'S A NEW HOSE NO ISSUES WITH IT. NOW WE ARE TRYING EVERYTHING WE CAN TO FIGURE OUT THE PROBLEM. WE CHECK ONLINE FORUMS AND FOUND OUT THAT THIS IS A HUGE PROBLEM WITH THIS CAR AND ALMOST NO ONE KNOWS EXACTLY WHAT IT IS TO FIX IT. WHEN THE CAR IS DRIVING IT SEEMS FINE BUT AS SOON AS YOU STOP AND IT IDLES IT SEEMS LIKE IT WANTS TO DIE AND ALMOST HAS A FEW TIMES. WAS JUST CURIOUS IF THIS IS SUCH A HUGE PROBLEM THAT SO MANY PEOPLE ARE HAVING WHY THERE HAS NOT BEEN A RECALL?
