2022 BMW X3 LANE DEPARTURE,FORWARD COLLISION AVOIDANCE

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.

The main windshield bracket holding the front camera (responsible for Driver's Assistant including front collision warning, pedestrian warning, lane departure warning, etc.) has the tendency to break on its own. The bracket is made of thin plastic and can melt under direct sunlight and/or usage of vehicle as the camera gets hot as well. Any reasonable exposure or usage will eventually cause the bracket to melt/deform and fail, causing the camera to fall from its original position. The misalignment of camera will cause a cascade of error codes and completely fail to work, rendering the entire safety systems to be useless. The bracket itself is not sold separately and requires the manufacturer to install a completely new windshield which is the only method of fixing this issue. Manufacturer and/or dealerships refuse to warranty if preventative methods are used (such as windshield tint) even though the camera or mounts remain untouched.
