2021 BMW R 1250 Rt

Original owner, purchased July 2021. Adaptive cruise control (ACC) continues to drop off intermittently after numerous complaints to BMW service techs and BMW Customer Relations since new. Attempts to repair include dealer 'recalibration' and software updates none of which have solved the issue. When in use, ACC suddenly, without warning drops out leaving driver to actively recover previous speed (throttle). Not such a problem at lower speeds, however at highway speeds the dropout could be life-threatening. In my case, traveling the posted 85mph highway speed outside of Salt Lake City, the ACC dropped out. The sudden deceleration nearly threw me from the motorcycle as if I had suddenly braked at highway speed. The highway was congested with the vehicle behind me having to emergency brake to avoid a collision. Most recently, on August 27th, 2024, I brought the motorcycle to a BMW dealership in Anchorage, Alaska for annual service and to request warranty repair of the faulty ACC unit. I showed images of the failure notifications, gave history of previous repair requests and repair attempts by other dealers. The service manager assured me he would contact BMW tech support to resolve the issue. After a mandatory software update and 'recalibration' I rode the motorcycle home. The unit failed three times over the 400-mile trip. Ultimately, the service center failed to complete warranty service on the ongoing life-threatening ACC failure due to lack of technical expertise to address the issue and false narrative of contacting BMW tech for a solution.

The distance control on the cruise control will just fail while in use. Going through Atlanta with cruise set at 65 MPH in traffic and it just fails (alert pop up too) and throttle goes to zero which on a motorcycle means immediate engine braking. Nearly get run over by car behind me. Has been to the dealer and they did a calibration and said it was fine only for it to return in about 200 miles. This is a new feature on these bikes and the dealer has no idea what to do at thie point. At a minimum BMW should look into this and get to the issue then notify all owners.
