What is the Mercedes-Benz Cruise Control Brake Failure Incident?

[LeVera]

On the evening of March 14th, on the Lianhuo Expressway connecting Henan to Shaanxi, a Mercedes-Benz C200L experienced cruise control failure, passing through toll stations at a speed of 120km/h, and was eventually controlled by opening the car door to reduce speed. The details are as follows: 1. Failure: The owner, an amateur racer, tried every possible method including contacting Mercedes-Benz after-sales service, shifting gears, braking, electronic parking, and manually downshifting, but all failed. The owner opened the car door, and the speed indeed dropped from 120km/h to about 60km/h. However, once the door was closed, the speed quickly returned to 120km/h. 2. Speed Reduction: The actual situation was that the owner unbuckled the seatbelt and opened the door, which caused the speed to drop, the cruise control function to turn off, and then deactivate.
