My concern relates to the recall campaign for 24V623000 reduction in regenerative braking. The slow roll out of this campaign caused this unrepaired recall to result in a crash of the vehicle resulting in a complete loss. While driving on a highway in subzero temperatures, the driver let off the accelerator to slow the vehicle around a corner. At this point the vehicle lost the expected braking and began to lose control. This sent the vehicle to understeer and toward oncoming traffic. An attempt to correct sent the vehicle out of control and into a collision with barriers, spinning across the road with the rear door on the driver's side completely ripped from the body. While the driver was not hurt, it is quite possible that a passenger could have been thrown from the vehicle and seriously injured. This is an obvious serious safety risk to not only the occupants of the car, but such loss of control could have resulted in death or serious injury without emergency corrective action and frankly a little luck. It is particularly concerning that very few of these recalls have apparently been addressed. It has been shared that fewer than 10% of the public vehicles have had this issue addressed, months after the recall was announced. I feel that had this issue been addressed in a timely manner this incident would not have occurred and I fear for others that might find themselves in a similar perilous situation.
