Fuel injector failed. The vehicle stall and accelerate poorly due to misfires. It is leaching gasoline into the oil which can result in total engine failure. Dealership verified the injector was bad. There was a warning light at one time after refueling, presumed it was my fuel cap, tightened it, and the light went away.

Car is a Sonata Hybrid Limited equipped with a solar roof which charges the hybrid battery. Vehicle began to cut off battery power while parked, requiring the use of a factory equipped 12V override switch in March 2025 after approximately 3.5 years of ownership. This occurred multiple times, often when the car was parked in the sun but independent of how long it had been driven prior or how long it had sat without being started. Evaluated by two Hyundai dealers; second dealer found a fault in the "solar DCDC converter" as well as the hybrid battery bulging. Battery module replaced. Unclear if this resolves the issue or it will recur again. Am speaking to Hyundai regarding battery warranty extension as vehicle had 88000 miles on it at the time of the issue starting. Online fora (e.g., Reddit, Facebook) note other customers who have had similar problems with similar fixes. - [XXX] - [XXX] - [XXX] - one individual in this thread had complete power loss while driving down the highway This issue potentially risks stranding customers, and if the hybrid battery continues to bulge increases the risk of fire which could lead to property damage, personal injury, or death.

Since a few weeks after buying the car new, the battery dies and self resets every few weeks on average. No error codes occur, but the car had clearly lost power while parked, indicating an issue with power management. For the last could months, car now has 26-27K miles and is 21-23 months old, it had mostly stopped resetting. It now is dead when I go out to it, even after only a couple hours of it being parked at night or during the day. I have to manually access the car and use the battery reset button. They observe no error codes. I have read other people have the failure while driving and fear and electrical issue could be a fire hazard. At the very least, it is a personal safety issue in making me take time to access my car, which could increase my risk of being attacked while trying to get into my car safely. It has occurred 5 or 6 times since August 21, most recently on October 8th and 9th.
