Our BMW iX was in B mode at a complete stop behind another parked car at the car wash. After about five minutes, the car took off at full acceleration and rear ended the car in front of us The BMW iX continued another 15 - 20 feet despite my attempts to repeatedly stepping on the breaks.
When overtaking a car on a freeway that is on my right side, occasionally the car, without warning and with no information displayed, my car will suddenly brake for no reason about 3 to 5 mph. I use the accelerator pedal immediately to return to the original speed. This has happened maybe 8 or 10 times. The car has 14,000 miles on it. My wife will not allow me to use the adaptive cruise control when she is in the car as she gets scared when the car suddenly brakes. She is afraid their may be a car behind that might hit us. I have not reported this to BMW.
