Owner's description

On 2/19/2026 while driving, my 2020 Hyundai Sonata Limited 1.6T began making several loud explosive / popping sounds. At the same time, the fuel gauge on the display screen appeared to rapidly drop, as if the vehicle was losing gas. Immediately following this, the vehicle began to hesitate and lose power while accelerating. The hesitation felt like the engine was misfiring or struggling to maintain consistent performance. There were multiple explosive sounds before and during the hesitation. This created a major safety concern while driving and the vehicle underwent an inspection at Hyundai in Deland, FL. The service department was brief and stated they needed to keep the vehicle for repair for an unknown amount of time as the fuel tank expanded. No further information was provided at that time.
