What 2023 Hyundai Sonata Hybrid owners say
Engine & cooling
The contact owns a 2023 Hyundai Sonata. The contact stated that while driving 75 MPH, the vehicle briefly lost motive power before downshifting to a lower gear. In addition, the engine revved independently. The contact was able to pull over to the side of the road and turned off the vehicle. The contact was able to restart the vehicle; however, the vehicle failed to exceed 60 MPH. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The failure persisted, and the vehicle was no longer being driven. The contact parked the vehicle at the residence. The contact started the vehicle and the check engine warning light illuminated. The manufacturer was not notified of the failure. The failure mileage was approximately 34,000.
UNKNOWN- While driving on highway, from 70 mph speed the car suddenly lost acceleration and speed dropped. No response to accelerator. Even with pushing the accelerator high, car will go in high RPM and speed will barely reach 40 mph. I was lucky that there was no other vehicle behind me, especially heavy automobile like semi truck as it would have crashed in me from behind due to sudden propulsion loss. The car started working fine next day. I took it to dealer and they couldn't find any error code but said it could be 12V battery BMS software update and they updated it. They mentioned that this is NOT a safety issue which is mind-blowing and concerning as this is a MAJOR safety hazard. I would request you to investigate this further and if this is a software issue then please direct Hyundai to update this with all vehicles and cover the cost for those who have had to pay for it.
Transmission & drivetrain
The push button shifters do not shift gears, unless the brake is depressed. On a slight incline, it is natural to shift from forward to reverse without braking leaving the driver in the wrong gear. So I have often started forward expecting to go backwards. I accidently ran over a portable toilet trying to quickly reverse out of a driveway on a slight incline. I hope no one has run over a person this way. I have had other close calls. This system is far more dangerous than lever style shifters. Even a little mistiming between brake and shift can leave the car going the wrong way.
The car did not shift from Drive to Park after coming to a stop and pressing the Park button. This caused the car to roll forward slowly and run into our garage door. This is not the first time the car hasn't shifted.
Fuel & propulsion system

The vehicle went in for repair at the dealership early July for a check engine light and DTC error code. It was revving high after being driven for more than 20 min or so and wouldn't get to above 60 mph. Jerky, dangerous acceleration and deceleration seemingly out of nowhere. The dealership replaced the fuel pump which is what they said was causing the error. Today on August 10th, check engine light popped up again with a DTC error code. Weird acceleration and deceleration and general jerkiness when driving. Scheduled service appointment for next week.
