NHTSA Complaint #11577737 — 2017 HYUNDAI SANTA FE

My 2017 Santa Fe experienced a catastrophic engine failure while driving on the highway. My [XXX] son was on his way home when the car began to make what he described as a knocking. He began to merge so he could exit the highway. By the time he made it over 1 lane, the vehicle began losing power and smoking. He barely made it to the shoulder before hearing a "loud bang" and thick, black smoke blocking his vision. Him and my [XXX] , fearing the vehicle was on fire, immediately exited the vehicle into the median. No warning lights ever came on in the vehicle, no warning, nothing. When my husband and I arrived, we found several pieces of the engine along the roadway and the oil pooled under the front passenger tire. We had the vehicle towed the next morning to the dealership, 50 miles away and a cost of $188. After almost 2 weeks we were informed by the dealership that our Engines For Life warranty denied the claim because we did not get all of our oil changes there, even though we have NEVER missed an oil change. We were quoted $21,000 for a new engine. Our service advisor informed us the point of failure for the vehicle determined to be "Cylinder 6 rod bearing failure causing rod bearing to exit vehicle at high velocity creating a hole in the block". We were also informed that this is a VERY well known issue with these engines but Hyundai had chosen to only extend warranties to select vehicles, ours was not one of them. A claim has since been filed with our extended warranty and we were told it would be an additional $600 to drop the oil pan to allow the inspection by the extended warranty company. Something has to be done. We are beyond thankful that our children were not injured but had this happened at a different time of day we could have had a significantly different outcome. There were on a highway that is very busy during the day. The undue financial hardship we have faced as a result has only further added to the stress of the situation.
