2023 Hyundai Sonata Hybrid

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.

The Hyundai Sonata was brought to a stop in a parking lot. When the driver went to put it in park, the vehicle accelerated across the parking lot and smashed into a solid wall. The driver broke her right ankle from standing on the brake pedal. The brakes were ineffective at stopping the vehicle. The collision avoidance system failed to activate or warn of the impending collision. The driver and passenger were severely injured and the car is considered a total loss. There were numerous other injuries sustained. No one outside of the vehicle was injured.
