NHTSA Complaint #11440588 — 2015 BMW 428I

The door locks have become ‘sticky’. This means that when pulling on the interior door release handle, the lock is moving to a stuck position that is not permitting egress. While the solution of pushing the central unlock button is currently viable, it would not work in a total electrical failure, or a situation of a vehicle submersion in water. This is a dangerous situation, potentially leading to passenger entrapment if the motors or lock mechanism fail. A manual unlock MUST be possible, but as this vehicle has aged, has become problematic. I experience this most on days with significant temperature swings, and will note that I experienced the exact same problem in my 2005 BMW 3 series, which was reported and repaired at cost to me, Basic passenger safety should not require this repair or cost. The mechanism in question is flawed and deserves investigation.
