UNKNOWN warning Iâm the owner of a 2011 Hyundai Santa Fe and a week ago at 185k mikes all of a sudden driving on the freeway it started hesitating and sounded like metal grinding and smoking really bad. Pulled to the side of the freeway on a ramp at that. Tried to restart the vehicle and I heard a bang noise which upon later discovery the engine blew a rod with no warning locked the steering wheel couldnât get the keys out of the ignition DO NOT buy this car still owe 5k on the vehicle
