Vehicle was driving on a slow traffic local street at roughly 10MPH. Spacing between car in front of me was around 30 ft. I was gliding towards front and ready to brake. Suddenly the vehicle start to accelerate hard by itself without driver’s operation. I tried to engage brake / gas pedal and was not helping. Front collision system did not activate like it suppose to. I ended up turn sharp right towards road curb and hit pole at average speed of 30mph or less. No air bag deployed. I then switch to Park. No warning lights pop up. All safety feat…

Owner report 11599576 · 2024-07-06 (July 6, 2024)
Rear foldable seats do not lock down into compartment. They bounce up when you stop just a little hard. Cable has already broken when this occurs. Anything laid on top of these seats when folded will be ejected inside of car. Hitting driver in the head. This is very dangerous. Already brought to dealer and complained and nothing was done. They said that's the way it is. Someone will die if this problem is not taken care of.
