NHTSA Complaint #11437425 — 2021 MERCEDES-BENZ SPRINTER 2500

My 2021 Mercedes Benz Sprinter van came equipped with Lane Keeping Assistance and Automatic Braking features that are on by default every time the engine is started. There is no way for an owner or a Mercedes Benz technician to have the safety feature set to remain off until the driver chooses to engage the features. I believe this is a safety hazard, as we experienced 2 incidents on a recent trip. 1. Lane Keeping Assistance took over the vehicle without warning from a slight wind gust, and almost caused us to get in an accident. We were traveling at 60+ mph on an interstate highway, and without warning, the van started to move from side to side and was difficult to gain control of the van. The MB Lane Departure Assistance was automatically braking different wheels of the van at different times to force the van to stay in the lane, but we never went out of the lane in the first place. If there was a car next to us, our 2021 MB van would have caused a severe accident. 2. Automatic Emergency Braking was engaged when the system thought a shadow from a light pole was an object in the road. We were traveling at 20 mph in a town center on a sunny morning, and the braking happened for no reason. We then saw the shadows. We would like Mercedes Benz to allow owners to turn off safety features, and have them remain off by default.
