My vehicle was stopped for several minutes on an upgrade, with stopped cars in front of me due to a traffic jam. I needed to keep pressure on the brake, lest my car roll backwards. After about three minutes, brake pedal lost pressure and my foot went to floor. The engine then went into gear and my car rammed car in front. Engine stalled on impact and was hard to restart.

While idling (vehicle running in electric mode) in park, for approximately 10 minutes we attempted to put the car in drive. The vehicle acted as if it needed to be turned on, displaying the message "Press Brake and Push Button to Start" while also displaying a red battery light. Different warning messages came up showing Traffic Sign Assist Unavailable and others. We could not turn the vehicle off even with holding down the start/stop button, were unable to shift the vehicle either. Finally after ten minutes of pressing the start/stop button the vehicle finally shut off and we were able to restart it with no issues. The next week as I was driving, I would randomly get a warning light with a red wrench and a message that said Service Hybrid System. Both instances have happen two additional times. The vehicle is now sitting at the dealership and they are unable to diagnose the problem. …

My dog in the rear compartment and in her kennel was also forcefully thrown. This vehicle has had on going battery issues and many others as well. This is not the first report I have filed. …
When accelerating at highway speeds there is a significant power lag when the vehicle switches from between the internal combustion engine (ICE) and the electric motor causing deceleration in the vehicle. This is typically followed by a sudden surge in power causing rapid acceleration. This causes unpredictable speed and makes merging onto highway traffic difficult. When this issue occurs the "Service Hybrid Electric Vehicle System" warning lights illuminates. After several miles, the warning will turn off, but this occurs off and on when changing lanes, merging, or braking in heavy traffic. This typically only occurs at highway speeds when the vehicles transfers between ICE and Electric power frequently and has not been observed at normal city street speeds. …
