Adaptive Cruise Control problems of the 2025 BMW X3

Subject: supplemental evidence for existing NHTSA complaint / odi #11711973 I am submitting supplemental safety information for my existing NHTSA vehicle safety complaint, odi #11711973, involving my 2025 BMW X3, VIN [xxx] . Since filing, I had an additional BMW of sterling visit/repair estimate dated April 22, 2026, mileage 17,628, ro #[xxx]. The dealer documented additional concerns including rough acceleration/jerking during the first drive of the day, intermittent a/c not blowing cold air and randomly blowing warm air, tire/wear concerns, left rear tire tread/screw concern, rear tires worn to 3mm, and alignment recommendation. This information supplements my existing complaint involving repeated unresolved safety/electrical/system concerns, including steering/safety concerns, driver-assistance/cruise-control malfunction, tire-pressure/tire-detection issues, key/door/alarm detection issues, hvac/defrost malfunction, and unintended movement/self-activation concerns. Please add this information and the attached repair estimate/photos/videos to odi #11711973. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While actively driving at speed this loaner vehicle, the vehicle's driving assistance professional package (dapp) completely deactivated without warning. This caused an immediate, unexpected loss of both adaptive cruise control and active lane-keeping steering assistance, requiring sudden manual emergency intervention to maintain control of the vehicle and avoid a collision. This is a severe safety defect. The vehicle has been presented to an authorized BMW dealership twice for this exact failure. It is currently on its second repair attempt and has been out of service for over 20 consecutive days. The dealership and manufacturer have been unable to permanently resolve my personal vehicle this electronic/steering system malfunction.
