NHTSA Complaint #11530169 — 2019 MERCEDES-BENZ SPRINTER 4500

Cruse control will sometimes disengage and display these error messages: "Active Distance Assist Inoperative" "Active Brake Assist Functions Limited See Operator's Manual" Cruse control kicks out and the power cuts off abruptly. After some variable time the cruise control function will work again. This is an intermittent problem that occurs without warning. When cruise control set to 65-70 mph, the deceleration is very pronounced, as if brakes are applied. This can be very starling to the driver, passengers, and any vehicles tailing behind. I reported this to a Mercedes-Benz Sprinter dealer, and they stated a released software update addressed this problem. However, after the dealer servicing, it still happens several times a day when traveling in our RV.
