NHTSA Complaint #11581580 — 2023 BMW 230I

Rear traffic cross is a joke. Had in the shop twice and was told it worked as required, took it and checked with cars coming behind me. Maybe worked 30% of the time if the other car was within 3ft. This is not a safety feature as stated. My Cad would notify me when a car was 12ft away.. was told the shop can't do anything further until BMW notifies them. No accidents yet but it may hit the car and not go off. Called the factory rep and he knew of other complaints but his hands were tied, put it inmy file. BMW needs to be able to rectify this with a reliable solution
