NHTSA Complaint #11600819 — 2013 HYUNDAI ELANTRA

The engine of my 2013 Hyundai Elantra GT failed due to a known piston-slap issue, and it is available for inspection for a limited time before being sold to a junkyard. This failure occurred suddenly while I was on the highway, putting my safety and the safety of others at risk as I had to maneuver the car to the side of the road amidst heavy traffic. The problem has been confirmed by both the Hyundai dealership and an independent service center, who diagnosed the piston-slap issue and found the engine filled with sludge, a known issue with these engines. Despite having 28 documented service records and regular oil changes, Hyundai denied the warranty claim, citing engine neglect. Hyundai representatives have inspected the vehicle and provided a technical bulletin documenting this defect. Prior to the failure, there were no warning lamps, messages, or other symptoms indicating a problem with the engine.
