NHTSA Complaint #11653112 — 2017 HYUNDAI SANTA FE

The engine in my 2017 Hyundai Santa Fe (VIN [XXX] ) began knocking, losing power, and showing signs of imminent failure. These symptoms directly match those identified in Recall #168 (NHTSA Campaign 17V578000), which involves engine bearing wear due to crankshaft irregularities in Hyundai 3.3L GDI engines. However, my VIN is not currently included in the recall batch. Hyundai has denied engine replacement under warranty or goodwill, citing a gap in oil change records between 5,000 and 45,000 miles — mileage which occurred before I purchased the vehicle used at ~60,000 miles. I have since performed multiple oil changes, though not always on a tight schedule. The vehicle is now at ~89,000 miles and located at Murdock Hyundai of Logan, UT, where technicians confirmed the engine is failing. This defect poses a serious safety concern due to the risk of sudden power loss while driving. The issue has been reproduced and confirmed by Hyundai service technicians, but they declined coverage and repair despite the failure matching a known federal recall issue. There were no warning lamps initially; the knocking and loss of power began subtly, then worsened rapidly. The vehicle is available for inspection, and all failure symptoms are consistent with others affected by Recall #168. I am requesting that NHTSA investigate this VIN for potential inclusion in the recall and take action to expand the recall scope, as this appears to be the same dangerous engine defect already recognized under federal recall.
