“On 11/28/25 at approximately 6:30 pm, I was driving on a Highway 17 going about 60 mph when my car's engine completely shut down. a Hybrid System Failure warning flashed and my car was no longer drivable. The car was towed to the dealership. In mid October 2025, my car stopped running with the same Hybrid System Failure warning, but it happened in my driveway. The car was towed to the dealership and supposedly repaired.”
NHTSA complaint #11702405, filed 2025-12“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. …”
NHTSA complaint #11704561, filed 2025-12“I bought this car brand new in november 2023, by february, the car started stalling on the streets/hyway. All dash lights would come on, the vehicle would stall and is no longer able to restart. This happened 4 time in 2024. When I tow it to the dealer, they always come back with the same answer. ''the AC motor power cable has been disconnecting leading to lose of power''. They have replaced it 4x but the same problem persist. It's very scary especially whn am driving in a busy road or when am driving at night in the middle of winter. Am not sure how to move from here. Thanks.”
