    - Selden, NY

    On Thursday, August 20th at approxmately 5:30PM my 2026 Mercedes Benz suffered a catastrophic transfer case failure and driveshhaft failure at highways speeds, causing a complete loss of propulsion. Putting me in immediate danger of on coming traffic. After the got to the shoulder I waited about 3 plus hours in pouring rain waiting for Mercedes Benz roadside assistance. The safety of this vehicle put me, my wife and family in immediate danger if this happens again. I do have a video I cannot upload as is is too large, but have loaded an image of the car in service showing transfer case. Please let me know how i can share the video.
