I am reporting a potential safety issue involving my **2026 BMW X3 30 xDrive**. I was parked on the right side of a parking lot. I moved the vehicle partially out of the parking space and slightly to the left to allow someone to enter the vehicle. I came to a stop and removed my foot from the brake while the vehicle was being held. I then turned toward the rear of the vehicle. The vehicle suddenly accelerated/moved forward across the parking aisle and struck two vehicles. The incident happened extremely quickly. I cannot state with certainty whether my foot inadvertently contacted the accelerator, and I do not want to speculate. I believe I attempted to brake. Of particular concern, I experienced **no apparent automatic collision-avoidance/emergency braking intervention before striking the vehicles**. Prior to this accident, I had expressed concern to a BMW advisor about the speed and acceleration of this vehicle while using its automated parking system. While the advisor was demonstrating the automated parking feature, I specifically commented that the vehicle was moving unusually fast and that I was uncomfortable with the amount of acceleration. I was told that this behavior was normal. On another occasion while using the automated parking/reverse function, I became sufficiently concerned about the vehicle's speed and acceleration that I applied the brake myself because I was afraid the vehicle could cause a collision. I had also previously raised concerns regarding inconsistent operation of the vehicle's Lane Departure Warning/assistance system. I have contacted BMW of North America and requested that BMW preserve and examine the vehicle's electronic and diagnostic data, including accelerator and brake inputs, Auto Hold status, automated parking system activity, Forward Collision Mitigation/Automatic Emergency Braking activity, sensor information, diagnostic/event logs and available crash/event data. I have specifically asked BMW to determine whether acc

2022 BMW X3 M40i. The Driver Assistance system appears to activate normally after startup with no warning or indication that a fault is present. However, within approximately 3–5 minutes of driving, a Check Control message appears stating “Driver Assistance limited. Camera vision.” The vehicle then identifies affected systems including Pedestrian Warning, Frontal Collision Warning, Side Collision Warning, Automatic Lane Change, Active Blind Spot Detection, and Steering Assistant. A separate message states that Active Cruise Control is reduced and there may be no brake intervention for stationary vehicles. The safety concern is that the system can appear active and available before the warning appears, even though at least some driver-assistance functions may already not be operating. Before the warning was displayed, I observed that Steering Assistant/lane-keeping did not intervene and I crossed out of my lane without steering correction or a lane-departure warning. There was no prior warning that the camera-based system was malfunctioning. I cannot confirm whether the other affected safety functions were operational during this interval. A BMW dealer inspected the vehicle and physically found the KAFAS camera hood/trim warped from heat. The warped component was removed and shown to me, and the dealer ordered a replacement. BMW has issued SIB 66 13 23 addressing KAFAS camera hood deformation on affected vehicles. Fault memory also contained KAFAS codes 800ABF, 800ABE, and 800AC4 for camera field-of-view disturbance and calibration failure. This creates a potential safety defect because the driver may reasonably believe lane-keeping and other camera-based safety systems are functioning until the vehicle detects the failure several minutes later. The vehicle/component can be made available for inspection

Beginning in July–August 2025, my 2019 BMW X3 (VIN [XXX] ) began experiencing multiple safety‑critical system failures affecting federally regulated components. The rearview camera intermittently failed to activate and later stopped functioning entirely, resulting in loss of rear visibility required under FMVSS 111. The Emergency Call (eCall) system displayed repeated malfunction warnings, indicating loss of automatic crash notification capability. The vehicle also displayed “Driver Assistance Restricted,” “Collision Warning Malfunction,” and pedestrian detection failure messages, showing that forward collision warning and related ADAS functions were not operating properly. During the same period, the telematics control unit (TCU) lost functionality. This caused loss of ConnectedDrive services, backend communication, remote diagnostics, remote status reporting, and safety‑related over‑the‑air updates. These failures match known BMW defect patterns involving water intrusion into the antenna/telematics module and backend provisioning issues. I submitted a detailed written escalation to BMW of North America. BMW issued two brief responses on February 11–12, 2026 that did not address any of the safety issues, did not provide the engineering basis for excluding my VIN from the applicable recall, and redirected me to a dealer, which has no authority over recall determinations. BMW closed the case without providing any investigation results, defect determination, or technical explanation, contrary to obligations under 49 CFR § 573. These failures materially impair federally regulated safety functions, including rear visibility, collision avoidance, emergency crash notification, and telematics‑based safety communication. The pattern suggests a potential broader defect affecting additional vehicles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Vehicle: 2025 BMW X3 Complaint Description: I am reporting a serious safety defect involving sudden unintended acceleration, braking abnormalities, steering looseness, and electronic system failures. Within days of purchase, the vehicle began experiencing infotainment system freezing and electronic malfunctions. Over time, steering looseness and abnormal brake behavior developed. These issues were reported to authorized BMW service centers but were not corrected or properly documented. On May 17, 2025, while the vehicle was stationary and in park, it suddenly accelerated without driver input after a passenger exited the vehicle. I attempted to brake, but the vehicle continued forward and collided with a stone structure, causing injury. BMW later claimed driver error based on post-collision data but ignored extensive pre-collision defect evidence. The vehicle was returned from repairs and continues to exhibit malfunctions. I believe this vehicle presents a serious safety risk to drivers, passengers, and the public.

I am writing to formally report a serious and dangerous safety defect affecting my 2015 BMW X3, which I believe warrants immediate investigation and a recall. Description of the Defect: On multiple occasions, while driving in rainy or wet road conditions, my BMW X3 has suddenly and forcefully reduced speed without any brake pedal input from the driver. The vehicle appears to apply braking on its own, causing abrupt deceleration. This behavior occurs: On wet roads only, while driving straight at steady speed without warning lights or alerts, without driver input and at speeds that pose a high risk of rear-end collision. The sudden and unexpected braking has created an imminent danger to myself, my passengers, and surrounding vehicles, particularly on highways where traffic flow is fast and close. Uncommanded braking under normal driving conditions is a critical safety failure. A driver has no reasonable opportunity to anticipate or correct this behavior, and it places the vehicle at significant risk of being struck from behind. Given the seriousness of this issue, I have requested that BMW: Formally investigate this defect across 2015 BMW X3 (F25) vehicles Determine whether a systemic fault exists involving DSC, ABS, wheel speed sensors, or collision mitigation systems in wet conditions. Issue a recall or safety service action to permanently correct this behavior in order to provide affected owners with a reliable and documented fix. Reason for which I wanted to bring this situation to the attention.

I am reporting a serious safety issue involving my 2024 BMW X3 purchased from Countryside Mitsubishi in Countryside, Illinois, on November 7, 2025. Within hours of purchase, I discovered multiple defects that were not disclosed before the sale. The most concerning issue involves the windshield wiper system and forward sensor components, which began to malfunction immediately. The vehicle’s onboard system initially flagged a windshield sensor fault. I later discovered that the original BMW windshield had been replaced with a non-OEM part, which BMW confirmed voided the vehicle's factory warranty and disabled key safety features dependent on OEM calibration. I was never informed of the windshield replacement at time of sale. When I raised concerns with the dealership, they admitted to using a sensor “workaround” instead of a proper replacement, which BMW later explained is not compliant with their specifications and leaves the vehicle’s advanced safety systems—such as forward collision alerts—compromised. The dealership falsely stated the repair was done by BMW-certified technicians, which was later denied by the repair staff. This defect creates a major visibility and safety hazard. I experienced intermittent wiper failure during poor weather, and the washer fluid system also failed to operate reliably. Despite repeated contacts, the dealership refused to install an OEM windshield or resolve the defect through an authorized BMW service provider. BMW has confirmed that their safety systems will not function correctly unless an OEM windshield and correct calibration process are used. This places me and others at serious risk during adverse weather or emergency braking situations. I have full documentation, a repair timeline, videos of the malfunction, and correspondence with the dealership. The vehicle is still in my possession and available for inspection upon request. I urge the federal safety agency to investigate this case for potential noncompliance and safety risk.
