Warnings problems of the 2021 BMW X3

The malfunction involves the collision warning system and sudden braking functionality. The dealership inspection identified a problem with the kafas (camera) unit, specifically its housing being deformed from heat, which affected the functionality of the collision sensor and caused the system to malfunction intermittently. The component is still installed in the vehicle and available for inspection if required. The system triggered sudden braking without an actual threat, creating a serious risk of being rear-ended by vehicles behind me. This issue has occurred twice in the last month, with no warning or actual collision risk present. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the problem was confirmed by the dealership. Their inspection found that the kafas camera housing is deformed due to heat exposure, causing malfunction warnings and erroneous braking behavior. They stated this is not a covered warranty issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the dealership performed an inspection and provided an inspection report, but no other entities (e. G. , manufacturer, police, or insurance representatives) have inspected the component or vehicle. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? yes, the malfunction indicator light for the collision sensor appeared intermittently. The dealership’s report attributes this to the deformation of the kafas camera housing due to heat exposure.
