“Around January 30, 2023 (need to verify the exact date). My vehicle went on limp mode, the engine light went on plus an additional warning light. I was driving on highway 99 when my car started to stall. It felt like the car put itself in neutral mode. It was frightening as it happens randomly & suddenly after being able to drive 60+ mph. It wouldn’t pick up speed. Driving 5 mph. It was frightening as I was far from the exit & the vehicles behind were honking and 1 swerved, thankfully the driver was able to change lanes. …”
NHTSA complaint #11567541, filed 2024-01“Let me start by stating that this incident is just one of many occurrences that has happened to me with this vehicle. I was driving down a straight highway that was pretty heavily congested with traffic of other vehicles, when all of a sudden I felt a loss of power with the vehicle and some error codes came up on the dashboard indicating the engine needed to be serviced, start & stop was unavailable, and to service electronic throttle control. I also noticed that the vehicle driving mode had switched by itself from Dynamic to Natural mode. …”
NHTSA complaint #11667062, filed 2025-06“Driving and stopped at a traffic light, car engin stopped then when I tried to start the engin burning smell and smoke came from under the hood. Took the car to the dealership and they advised me that the starter had been completely burned out but yet they don't know why or how. This incident had made me fearful for my kids, wife and my life, the starter is close to gas lines and that could have caused an explosion. I am not sure how can the starter burn in flames when there is a relay and fuses to protect the regulation of current going into the starter. Thanks”

I was in the passenger seat and had my right elbow resting on the window sill (the window was fully open) and my palm was resting against the window frame. My wife pressed the automatic window up button as she was turning off the car. As the window started up, my forearm was trapped between the sill and the window frame. the pain was extremely intense, particularly from where the window kept trying to close. I yelled at my wife several times to hit the window down button. …”
