I am writing to formally raise a critical safety concern regarding the performance and behavior of the Crosswind Assist system in my 2020 Mercedes-Benz Sprinter 3500, upfitted by Airstream as a B-Class RV. This vehicle, identified by VIN [XXX] , exhibited behavior that I believe constitutes a significant and potentially dangerous flaw in its integrated driver-assistance programming. During a westbound trip from Minnesota to Nevada—traversing high-wind corridors in South Dakota, Wyoming, and Utah—the Crosswind Assist system activated on multiple occasions while overtaking large trucks during gusty wind conditions. The system appeared to override driver input by abruptly applying the brakes and modulating throttle response. On one particular occasion, this intervention forced our vehicle laterally toward a semi-truck in the adjacent lane while simultaneously initiating a hard brake event. This caused not only a near side-impact collision but also a chain reaction behind us, as trailing vehicles panic-braked, narrowly avoiding a rear-end collision. This level of autonomous intervention, especially under highway-speed wind shear, presents what I consider a severe safety risk to occupants and other motorists. No reasonable amount of driver anticipation, route planning, or wind-speed awareness could have prevented the unintended and forceful application of braking and steering commands we experienced. Upon referring to the owner’s manual and engaging in discussions on several Airstream and Sprinter-owner forums, I discovered that other owners have experienced similar incidents. Some users referenced the ability to disable the system through authorized Mercedes-Benz diagnostic software. Based on this information, I scheduled a service appointment at Mercedes-Benz of Farmington, Utah on March 17, service invoice [XXX].

My vehicle is listed as one of the 2100+ sprinter vans affected by the incorrect assembly of the torsion bar(Manufacturer Recall Number 2022030013; NHTSA Recall Number 22V131). This recall was issued on March 17, 2022. It has now been over 120 days since that recall was issued and the parts are not yet available.

Mercedes Dealership is refusing to get the vehicle in to make this safety recall repair in a timely manner. I have been told that i will need to wait for over a month just to drop the vehicle off with no time frame given in terms of how long the vehicle will be gone while being repaired.
