NHTSA Complaint #11530571 — 2016 HYUNDAI SONATA

1. The component or system that failed or malfunctioned is suspected to be related to oil consumption or engine failure, as indicated by the burning of 1 quarts of oil within 400 miles driven, premature burning of spark plugs (The spark plugs, which were replaced prematurely, can be made available for inspection upon request), stalling of car, not accelerating, and failing twice within a months' time. 2. The safety of both myself, my family and others were compromised due to the potential engine failure caused by the oil consumption issue.

They mentioned oil consumption but advised me to monitor the situation. However, on 5/22/2023, the car stalled and died in a parking garage, resulting in a delay of 5 hours before I was able to drive it home. Subsequently, on 5/23/2023, I took the car to the
