Other Fuel System problem #1

When gas is pressed (even to floor) in drive, vehicle stalls, does not accelerate. Then vehicle jerks into propulsion after revving. Other instances, at deceleration the car will jerk and shake to a stop. I have mentioned the problem at every scheduled maintenance.

Other Fuel System problem #2

I keep getting intermittent hev warnings and 12-volt light. The engine then shuts down and I have no power. This has occurred several times while on the highway and this creates a safety hazard. I have been fortunate enough that this happened while I was close to the shoulder, otherwise, it could have been critical. - the failed component(s) are the 12 volt battery and engine shutdown - with the vehicle being without power while on the highway puts other drivers and myself at risk of an accident - I have taken the vehicle to two different Hyundai dealers and they have not resolved the problem - the issue was escalated to the manufacturer Hyundai motors and they have not resolved this issue. - the 12v battery light and an hev warning light comes on and then the engine shuts off - this issue has been happening intermittently for the past year and I first notice it on October of 2022.

Other Fuel System problem #3

The h e v warning light comes on when driving. The hybrid battery disconnects from the engine and the car is undriveable. Have to pull over, stop the car, turn off the car and then reset the hybrid battery. This has happened twice in last week. Thank fully I was able to pull over safely, but this a dangerous situation for me and other cars around me. The car had been taken to the dealership just two weeks ago and they were unable to diagnose the issue.

Other Fuel System problem #4

While driving the car suddenly turns off. It puts me at risk because if I am in a situation where there are other cars, I can be hit and undangering my life and others! this problem happened suddenly and the car restarted only to fail again,multiple times. Towed to dealer /danbury Hyundai and they claim not to find problem. The car had a full tank of fresh gas. This happened without warning.
