20250708LANE DEPARTURE: ASSIST
I am filing this complaint regarding an ongoing safety issue with my 2021 BMW 740i involving the lane departure warning system, lane keep assist, and adaptive cruise control, all of which have stopped functioning properly. These features are critically tied to the windshield-mounted KAFAS camera, which Iâve now been told needs to be replaced. Initially, the BMW dealership attributed the issue to a software problem and charged me $500 for a software update. After the update, the driver assist systems remained non-functional. The dealership then diagnosed a failure with the front camera assembly and is now quoting me approximately $3,000 for replacement of the windshield and camera module. I have reviewed NHTSA Technical Service Bulletin SIB 66 08 23 (NHTSA ID: MC-10236236-9999), which outlines this exact issue, suggesting that BMW is aware of system limitations and hardware failures in this critical safety feature. However, this has not resulted in a recall or manufacturer-paid repa
