2024 BMW X3 — Problems, Recalls & Safety Data

To Whom It May Concern, I am submitting this supplemental update to formally document continued delay and lack of action by BMW following notification of serious vehicle safety concerns involving risk to minor passengers. BMW was notified in writing of multiple safety-related incidents involving system reliability and unauthorized access behavior. These concerns escalated to an incident occurring while the vehicle was in motion, presenting immediate risk to occupants, including two minor children. Despite acknowledgment of these concerns, BMW has: Failed to open a repair order to document the safety defects; Conditioned inspection on continued operation of a vehicle reported as unsafe; Failed to provide a timely, safe alternative path for inspection (e.g., coordinated tow and uninterrupted transportation); Gone silent for extended periods after acknowledgment of safety risk. I have expressly stated that the vehicle is unsafe to operate and that continued delay creates ongoing risk. I have also stated my willingness to cooperate fully with inspection and documentation provided that such cooperation does not require placing occupants at risk. This supplemental notice is submitted to preserve the record that continued inaction following acknowledgment of a safety concern may constitute failure to mitigate known risk. All communications, incidents, and delays are being documented. I respectfully request that this update be added to the record and considered as part of any safety or compliance review. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This submission is a supplemental update to my existing NHTSA complaint regarding my BMW X3. On [XXX], at approximately [XXX], while the vehicle was traveling approximately 40 MPH with the doors locked, the rear passenger door opened while the vehicle was in motion. A [XXX] child was secured in a rear car seat at the time. A [XXX] child witnessed the event while I was dropping him off at school. No audible or visual warning alerts activated before or during the incident. This event follows prior electronic access and system reliability concerns reported in November and December 2025, including operation without key presence and unauthorized access behavior. I believe these events may be related and indicative of a broader electronic or body control system failure. Due to the seriousness of this incident involving minor occupants, I no longer consider the vehicle safe to operate. The vehicle is pending inspection and has not been driven further. I am submitting this update to document a potential child-safety defect and to ensure this information is considered as part of NHTSA’s review.

I am submitting a supplemental update to my existing safety complaint regarding my BMW vehicle. On December 29, 2025, additional safety-related malfunctions occurred while the vehicle was parked and without the key present. A vehicle window rolled down autonomously, and the heating system temporarily stopped functioning during winter conditions. These failures follow an earlier incident on November 15, 2025, in which the vehicle continued operating without the key present and without any audible or visual warning, while two minor children were occupants. The involvement of multiple electronic systems—including key detection, window controls, and HVAC—suggests a potential electronic network or CAN-bus-related defect. These conditions present risks related to vehicle security, environmental exposure, and passenger safety. The vehicle is currently unsafe for transport of minors and unreliable for use during winter conditions. I am submitting this update so NHTSA’s records reflect continued post-notice safety malfunctions.

Supplemental Update – Manufacturer Response to Safety Complaint (BMW) I am submitting this supplemental update in connection with my existing NHTSA safety complaint regarding my BMW vehicle. Following my report that the vehicle continued operating without the key present while transporting minor children, BMW of North America acknowledged the concern and indicated it was under review. However, BMW has now stated that it is closing my case file without: • Conducting any inspection; • Issuing written findings; • Providing a safety explanation or analysis; or • Confirming whether the reported behavior is a defect, system failure, or normal operation. BMW has conditioned further assistance on dealership inspection while simultaneously closing the manufacturer-level case, creating a gap in accountability and preventing meaningful review of the safety issue at the corporate level. I am not refusing inspection and remain willing to present the vehicle. My concern is that BMW’s attempt to close the case prior to evaluation undermines safety reporting and limits transparency regarding potential risks to drivers and passengers. Please add this update to my complaint record for consideration in any review or investigation.

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 NHTSA to investigate this case for potential noncompliance and safety risk.
