NHTSA complaint #11669758

Owner complaint summary

The emergency call warning on the dash was activated. GPS and Heads-up display no longer functioned correctly. BMW Dealership replaced TCB2 Box and battery at a cost of $2956.63. In researching this issue found numerous complaints from other owners. Contacted BMW and was told they were not responsible, car was out of warranty (4yr / 50,000 mi). This is an electronic component that is positioned in the least hostile environment of the vehicle. It has NO moving parts, is located in a dry / protected area (above the headliner), has NO knobs to turn / buttons to push / or screens to touch and is not subject to normal wear and tear. One of 2 things seem to be the case: This is a rare failure of this component - in which case I would think BMW and the manufacturer would be not only interested to investigate but also responsible. This is a regular failure of this component and since it is an integral part of the car's safety system BMW does not want to acknowledge a known defect.
