Three problems related to automatic emergency braking have been reported for the 2022 BMW X3. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2022 BMW X3 based on all problems reported for the 2022 X3.
The BMW front facing kafas camera system is prone to failure in the BMW X3. The plastic piece that holds the camera module in place has small plastic tabs that attach it to the windshield. These tabs are prone to breaking. Once the tabs break the front camera system is no longer in alignment and all front safety systems will be disabled. This puts the occupants of the vehicle in danger as all front facing safety systems will be disabled. The dealers do not want to warranty these failures as they try to pass it off as the fault of the owner. The first dealership rejected my issue saying that since my vehicle has a modified suspension that the camera is not able to calibrate which is incorrect. The second dealer I took it to saw the problem was the failed plastic mount but since my front windshield is aftermarket uv rejecting film it must have been damaged by the individual that installed it. This is not the case since the film did not extend behind the plastic pieces covering the electronics. In order to get this issue fixed I to pay out of pocket $2000 even though my vehicle is still under warranty. This issue has been reported by several people on various BMW forums.
Mount for BMW kafas camera melts/deforms in the heat (normal exposure). This causes the camera to become uncalibrated and disables pedestrian avoidance braking as well as lane keep assist. I am unsure what other functions are unavailable. After 2+ months of waiting for a new part, the BMW dealer nor BMW na could not give a timeline on when the windshield/mount would be available for replacement. This means that the safety features that were advertised and paid for by the owner are unavailable to the owner for an indeterminate amount of time. Forum participants indicate that this is a common problem with this model with some owners experiencing multiple failures of this safety system in a short period of time during summer months.
I have lane keep assist set to early with steering intervention. Lka would sometimes shut off by itself in the 45-60 mph highway speed range in sunny weather with clear road markings, and sometimes would stay on even when my speed decreases even to 35 mph instead of 40 mph. I understand if weather is bad, lka might not work, but I am very confused, in broad daylight, what would cause the lka to turn on or off and deactivate/activate at different speeds? I have the standard pdc with the "forward and rear corner sensors that trigger a warning beep at approximately a 2 ft. Distance from the object. " is there any way to control the distance the parking distance control sensors activate automatically like in merc? since I don't have active park distance control (option zx1) which "automatically applies emergency braking when the reversing vehicle gets too close to an object behind or at the side of the vehicle when a collision is imminent at speeds below 3 mph," would the car still auto brake for me if I am backing up reverse in a parking garage if there is cross traffic alert or I am hitting object behind me?.
