Failed component: engine - burnt valve/ snapped piston/ piston scrapping internally; available for inspection - risk of safety: car sputters/jerks upon acceleration, takes a long time to gain speed, stalls when slowing or stopping, may or not start after stalling, violently shakes while driving - problem has been confirmed by Hyundai dealer/repair - component has not been inspected by the manufacturer, police, insurance representative; only Hyundai repair - warning lamp, messages, and symptom prior to failure, no, after the failure, yes; check engine light and all symptoms listed above; all appeared approximately September 15, 2024. Since the purchase of the vehicle in January 2024, I have made complaint regarding the performance of the vehicle. Have had multiple oil changes/fill ups within the last 7 months, due to excessive oil consumption. Vehicle has had scheduled maintenance, several diagnostics, and too many trips to the dealership/repair for a 5 year old vehicle, with regular maintenance, and 3 owners. I have owned the vehicle for less than a year and I am unable to drive it due to Hyundai stating it needs a new engine. It stalls when slowing and stopping, which it may or may not start back up - this happened a few times in the middle of traffic. It will not gain speed appropriately when moving from a complete stop, inhibiting me from keeping up with traffic. It shakes violently while accelerating, causing mishandling and ability to steer effectively.
2019 Sonata 2. 0t with just over 11k miles on it began to suddenly studder and want to stall at low rpm or at the stop. Obdii error code p0302. Dealership said cylinder 2 had little to no compression and needed repair. Could barely limp vehicle to dealership and smell the unburned fuel being ported out of the exhaust.
