The active distance assist inoperative appears when using the cruise control. This comes on when no traffic in front of the vehicle for 1 hour or less. Also Active Brake Assist functions limited - see operators Manual To reset: follow another vehicle for 5 minutes. This is Very Very Very frustrating and UNSAFE. This function should not automatically shut off. I paid a lot of money to try and figure out the problem. This is VERY UNSAFE for this feature of instantly shut off for no reason and is dangerous. Please fix this with a software update and allow me to download it at my dealer for no charge. Not happy as I use my cruise control on long trips in the USA.

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.

Jun 23, 2021Lane DepartureBackup camera & sensorsDriver assistance

The Lane Assist and Crosswind Assist do not work properly. When a gust of wind hits you or when you're passing a semi, the van immediately forces your vehicle off the road or into the other lane where there is another vehicle or a concrete barrier. It's very difficult to hold onto the steering wheel and try to maneuver the vehicle to stay in your lane. The only way to turn off these features are to turn off them off every time you start your vehicle. Mercedes Benz has told me there is no way to turn it off completely and they have had numerous complaints of unsafe vehicle responses from the assist features.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2019 Mercedes-benz Sprinter 4500 verdict →
