2025 BMW X3 Forward Collision Avoidance Warnings Problems

My wife was driving our 2025 BMW X3 in traffic and when the car in front braked suddenly. She tried to change lanes but clipped the car in front, resulting in nearly $22 thousand in damages. BMW's review of the car's "black box" purportedly shows that the Forward Collision Mitigation system engaged, but only a split second prior to the crash, which my wife did not experience. BMW's review also purports that my wife did not brake, which she also disputes. Even more concerning is that the parts need to repair the car seem to be completely unavailable from BMW--the car has been sitting in a body shop for almost 2 months and BMW has "no ETA" for the parts.

While driving on a state highway in cruise mode, the vehicle displayed a “CHECK CONTROL” message: •Support from Driver Assistance restricted •You can continue driving. Driver Assistance permanently restricted. •Check Control messages (1) Suddenly, the car exited cruise mode. While this is designed as a safety feature, it should not disengage abruptly during driving, as it may lead to potential risks. This a second biggest issue with this vehicle within just a few months of purchase.
