The Distronic Cruise Control stops working and then will start working again several times on long trips. After research it appears if the radar doesn't detect anything in front of your vehicle for an hour it thinks it is inoperable and and shuts the Distronic Cruise Control off and it cannot be reengaged. If it detect a vehicles in front of you for four minutes or more it will reset the radar and your Distronic Cruise Control can be turned on again. This is dangerous as it requires you to follow closely behind another vehicle for at least four minutes to reset. Out west where I live there are a lot of road stretches' where you will have little to no traffic for over an hour. Mercedes needs to change this software bug and provide another method for it's radar check warning.

On long trips (when you need cruise control the most) the adaptive cruise control will (seemingly at random) stop working with a warning about the active distance assist and active brake assist. It has happened in all situations from heavy traffic to long distances of no other cars on the road. It stays non-functional for anywhere from a few minutes to several days. It has happened many times. The dealers are clueless. Saying nonsense like "I'm not aware of this problem." even though the Internet is filled with reports of the exact issue.

Is 9 complaints a lot? They were filed between 2021 and 2024, roughly 3 a year, which is more than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.
