Rearview System Braking problems of the 2019 BMW X3

Starting in July/August 2025, my 2019 BMW X3 (g01) suffered a total failure of multiple safety-critical systems, including the emergency call (ecall) system, the rearview camera, and frontal collision/pedestrian alert sensors. These failures were accompanied by a persistent "emergency call system malfunction" warning on the dashboard. BMW service information bulletin sib 65 12 22 acknowledges a manufacturing defect where the roof-mounted antenna housing seal was "not optimal," leading to water ingress. This water ingress has damaged the telematics control unit (tcb), which manages these safety features. I have contacted BMW north America and local dealerships; however, they have provided a written refusal to repair the damaged internal electronics because the vehicle is out of its original 4-year warranty. Safety risk: this defect leaves the vehicle in a non-compliant safety state. In the event of a crash, the vehicle cannot automatically notify emergency services (ecall failure). Furthermore, the loss of the rearview camera and collision avoidance systems significantly increases the risk of a crash or injury. BMW is aware of the defect that causes these safety systems to fail but has not issued a safety recall to address the resulting hardware damage. This issue is currently the subject of the craft v. BMW of north America class-action lawsuit.

Hello I am formally reporting: safety?critical failures and applicable federal requirements the attached 2019 BMW X3 – VIN [xxx] 1. Rearview camera failure federal requirement: fmvss 111 – rear visibility relevant obligations: - rearview image must activate automatically when shifting into reverse. - system must provide a minimum field of view. - system must function reliably under normal operating conditions. Failure: the rearview camera failed completely, resulting in loss of federally required rear visibility. 2. Emergency call (ecall) system malfunction federal requirement: 49 cfr § 573 – defect and noncompliance responsibility (NHTSA considers ecall part of the post?crash safety architecture. ) relevant obligations: - manufacturers must investigate safety?related failures. - manufacturers must determine defect scope and affected population. Failure: the vehicle displays “emergency call system malfunction” warnings, indicating loss of automatic crash notification capability. 3. Forward collision warning / pedestrian warning failure federal requirement: fmvss 126 – electronic stability control (esc) - NHTSA adas safety guidance (forward collision warning, pedestrian detection) relevant obligations: - adas systems supporting collision avoidance must function reliably. - failures must be investigated for potential safety defects. - manufacturers must document defect determination and scope. Failure: the vehicle displays warnings indicating failure of forward collision warning and pedestrian detection systems, impairing collision?avoidance capability. 4. Telematics control unit (tcu) failure federal requirement: 49 cfr § 573 – defect reporting - NHTSA safety recall rules (tcu failures affecting safety systems) relevant obligations: - tcu failures affecting safety?critical subsystems must be investigated. - manufacturers must determine whether the failure constitutes a defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
