Adaptive Cruise Control problems of the 2022 BMW X5

I was pulling into a parking spot. I was riding slowly into the correct position. Immediately the car went into full acceleration. Knocked the parked car in front about 8 feet, turned and knocked another car on the side. I stood on the breaks, it went another 10 feet and engine stopped. I never heard this level of acceleration of engine ever before. The airbags for me and my passenger did not open. I think this spurious acceleration is a control system defect.

East bound on us 20 and barrington road in hanover park IL. I was in the right lane and had stopped at the light, about 3rd or 4th car back. There was a semi-truck in the middle lane (on my left). Assisted driving/adaptive cruise control (cruise mode 2) was active. The car automatically accelerated from the light. When I entered the intersection, the car sounded a warning alarm and braked very hard momentarily, but did not stop the car. I was quite startled and did not notice an alert in the dash. Braking was so hard and so sudden I felt lucky that I was not rear ended by the car behind me. There was nothing in my path. Just beyond the intersection there is a rail road overpass. The road curves slightly to the right just beyond the intersection and is slightly downhill to go under the overpass. There was a freight train on the overpass, all tanker cars I believe. My speculation is the car's sensors "saw" the freight train as a potential collision, perhaps cross traffic. And the car's safety systems were applied.

2022 BMW X5 adaptive cruise control (a very expensive option) will not reliably stop or accelerate your BMW. It is dangerous and unsafe and should be eliminated until it will brake safely. I have a video that I was unable to upload. This system if left to stop your vehicle will crash a occupants into a stopped vehicle. Always brakes to late. Scares all occupants. Not safe to use in traffic, not safe on the highway, it’s not safe, period. How is BMW permitted to sell an advanced cruise control system, that is to safely stop and accelerate a BMW if it doesn’t? if it can’t stop a vehicle autonomously with a driver actively engaged, what distinguishes this from standard cruise control that requires a driver to be fully engaged. In 2022, and since 2000, this is not advanced cutting edge technology. Dont by a BMW, they dont care if they are selling a dangerous system. I would not use this system if it was free. Brakes have to work 100% of the time. Anything less when it comes to braking your vehicle is very dangerous.

New 2022 BMW X5m with a little over 200 miles on it. Received a message stating, "driver assistance support reduced". This driver assistance package controls many of the safety features listed above, and then some (could only select 3 from the list above, but affects more). Sad part is, after minor research, I find this has been an ongoing problem with BMW for years, and has not been addressed as the problem still occurs in their cars.
