BMW X3 door locks problems

Filed Jan 7, 2026 · Electrical · MD

This submission is a supplemental update to my existing the federal safety agency 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 the federal safety agency’s review.

The driver side rear door locking mechanism keeps locking, even when the car is unlocked with the key fob. This is a safety concern, as our granddaughter rides in the rear seat regularly and if an emergency arises where I need to get her out of the back seat quickly, the rear door can stay locked and not allow me to get her out. There were no warning notices for this issue on the dashboard system.

My X3 has 52,000 miles. During a recent road trip, an "Emergency Call System Malfunction" message appeared. When I returned home, I took the vehicle to the dealership. The advisor said the shark fin trim is loose on the roof causing water ingress into the vehicle causing damage to the aerial antenna and the TCB unit. The TCB unit is also known as the Telematics Control Unit that is responsible for vehicle safety and connectivity features, door locking mechanisms, and so on. The technician found faults in the aerial antenna and TCB. I understand from the service advisor that they see this fairly regularly. I have further learned that BMW issued a Service Information Bulletin admitting the problem to dealers and telling them it was a manufacturing defect during the painting process and lists the parts needed to fix it. The quoted cost to replace the damaged components and install/seal a new shark fin was over $4,000 (almost 10% of the car's original price). BMW knows this to be a problem and I think there should be a safety recall for it, regardless of whether the car is out of its original warranty period.

Junction box failure. I started having all types of random electrical problems. Wipers come on at random. Door locks, back windows, and turn signals won't work when this happens. I read that this issue was happening in other models, but don't see that the bmw x3 itself wasn't called out. Had the issue looked at by a mechanic and he said the stored codes were for main junction box failure or no message received from main junction box. It doesn't matter if the vehicle is stationary or in motion, issue still happens. Sometime when I turn off the car, the wipers are still going. Sometimes if I just open the door, without turning on the car, the wipers will start to go.

When I turn on the car, the electrical dashboard has a delay. I turn on the car, start to drive, the dashboard will delay in turning on (happens at least 1/month in the last 1.5years). Winter 2015/16 doors would not lock manually or by key fob. In fear of theft, I drove home and the doors would not lock. Additionally, dashboard notification said driver side door was ajar while driving (took pictures). Lastly, trunk release is constantly jammed and can't be opened manually, trunk release button, or key fob. From time to time I will not have access to the trunk and have to go through the back seat. I have been to my local bmw dealership in summer 2016 and the problems still occur.
