Owner report 11591510 · 2024-05-30 (May 30, 2024)
My car randomly engaged emergency brakes while driving 70+ mph on the highway with no cars nearby. It almost came to a complete stop but i was able to accelerate again. it was not acting as a safety features because there was not a car close to my front. I am concerned if it happens again i could get in a crash and rear ended. The dealership does not seem concerned

Owner report 11704561 · 2025-12-11 (December 11, 2025)
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 soft…

Owner report 11679707 · 2025-08-10 (August 10, 2025)
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 fo…
