NHTSA Complaint #11522038 — 2019 BMW X3

I am writing about the BMW Telematics Control Unit (TCB). This is a safety device installed on all BMWs for the past 6 years or more. It is an electronic tracking and communication device that is activated either automatically on manually in the event of an emergency. For minor emergencies such as a flat tire or running out of gas, the driver can call for roadside assistance. For serious emergencies such as accidents the system automatically contacts the BMW emergency center who contacts local emergency assistance providers such as police, fire, ambulance. The system provides information such as the vehicle's exact location and the severity of the accident. Obviously, this can be lifesaving information. I have no way to determine how frequently these systems fail, but judging from the countless number of accounts described on the internet and the number of YouTube videos I see, it would appear that these systems are very unreliable. These systems fail for a number of different reasons and are very expensive to repair. This is a serious safety issue. In my own case, water had leaked through the roof aerial and damaged the electronic communication device rendering it useless. Cost of repair would be nearly $3,000. There is at least one BMW Technical Service Bulletin (TSB) that applies to this issue for my vehicle. It is number B651222. There are probably many other TSB's that apply to other models and other causes of failure of this device. BMW owners have spent a lot of money for this device with the expectation of providing themselves with some additional safety in the event of an emergency. This is largely a false sense of security because these devices are very unreliable. I respectly request the the NHTSA look in to this issue. I believe that there are many people that are unknowingly in a dangerous situation.
