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 van has periodic lack of acceleration or dead pedal. There are no warnings that this will occur. This shows itself when trying to advance from a stopped position. When I push the accelerator the van either does not move at all or barely crawls forward. This can last 15-45 seconds. There are no RPMs from the engine. Once the pedal starts to respond, the issue will resolve. The problem is you need to get to that point where the engine can make rated power. Once you put in in drive, and if you're able to idle away from the parking spot, you may find that when you need power to move up a hill or through an intersection, it just isn't there. You can't wait a minute with your foot to the floor when you're in the middle of an intersection. sometimes it will slowly accelerate. This has caused multiple situations where I thought I was going to die due to being out in cross traffic and failing to be able to move. It happens both in reverse and forward. It happens even though I have warmed up the engine for 5 minutes or more. It seems to happen more at altitude but has also happened at sea level. It doesn't seem to matter if the outdoor temperature is warm or cold. The dealer can not detect a problem. I have read many accounts of this happening on MBZ forums. This must be a known issue with MBZ yet they have failed to solve it. Some think it is a sensor initiation issue after a cold soak. Someone is going to die because of this problem if MBZ is not forced to fix it.

I started my Sprinter, which was converted into a Grech RV, and while still in park a few seconds later, the vehicle started to move. Before I could hop back in the driver's seat to stop the vehicle, it crashed into my garage overhang and significantly damaged my Sprinter's back doors and back structure. How it started to move was a complete mystery to me as it was in park and I had just started the vehicle a few seconds prior. While doing some research, I saw an article in an auto blog forum about Sprinter Van roll-aways. I then received a safety recall notice from Mercedes about this very issue that I experienced. This involves NHTSA Recall #22V796. The incident was reported to my insurance company and the vehicle is currently awaiting repair. Thankfully, no one was injured.
