My vehicle offers rear traffic alert system, but it is not working properly. It's a safety issue that I almost caused several accidents because of it. The vehicle is available for inspection. Safety to me and others are at risk because the feature is not working (rear traffic alert system). I have an appointment on may 28, 2026 to have the BMW dealership look into it. There were no warning lamps or messages.
The rear cross tracking warning system does not provide an audible warning or apply brakes. The settings have been set, and verified with the dealer, including the most sensitive sensor level and loudest audio alert level. I have gone to two different dealers in ohio and florida and got the same response, “it works as designed”. My brother in law has a 2023 BMW 440i and has the same issue, with the same results with dealer responses. It’s a well known issue in the BMW community since 2019 models, yet the company doesn’t fix. Not only is it dangerous backing out of parking spaces etc. , but it causes a lack of faith in the other critical safety features which you rely on, but cannot easily check; like adaptive cruise and forward collision features.
