My wife has experienced the same trouble during to park it in to our garage on last week.
The car is 2015 Rex.
After she has stopped the vehicle in front of the porch, it showed some kind of fault message on display.
And suddenly it start to accelerate and run against the stairway in front of the porch.
The car is loaner vehicle from BMW dealer and waiting for delivery of i3...
She had a whiplash injury and hospitalized yesterday...
I am waiting for the report from dealer of BMW..
When we've got the report from them, I would like to share it.
Did the airbags deploy?
The reason I ask is after the 'unintended acceleration' claims against Toyota in 2009, all car manufactures are required to have accident data recorder, a type of black-box. One reason for embedding them with the airbags is they often have a capacitor with enough energy to record the data in nonvolatile memory. An airbag is fairly effective as an accident signal.
Several 'lessons learned' from Toyota's experience:
- accelerator pedal has two 'pots/sensors' - these should have different slopes so a simple short can not lead to a false, acceleration signal. Any combination of ground and short should lead to an error and the car going into 'safe hold' mode or even disabled. The Gen-1 Prius had mechanical pots and there were known to put the car in 'safe home' mode also called 'the big hand syndrome.'
- brake and accelerator pedals are too close - studies of Toyota accidents are consistently showing the accelerator was floored instead of the brake. HOWEVER, each case must be evaluated individually using data, not speculation!
