This happened while driving on a highway at the end of a bridge going downhill so I was able to pullover to the shoulder before the vehicle came to complete stop but if this happened while on the bridge going uphill, that could've been extremely dangerous as there was no shoulder to pull over to. This has happened about 5 times already and we've taken it to the dealership. They upgraded the vehicle's software at one point saying that would addres…
The contact owns a 2023 Mercedes-Benz EQS450. The contact stated while driving over a bump in the roadway and depressing the brake pedal, the vehicle failed to immediately stop, causing the braking distance to become extended. The contact stated that the failure occasionally occurred while braking without driving over a bump in the roadway. The vehicle was taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not yet contacted. The failure mileage was 1,000.
Active Emergency Stop Assist Inoperative warning has shown up more than once and the dealer can not duplicate the warning or repair. It is causing frequent phantom braking and sudden stops both in normal driving use and cruise control.

So I've had to have 1 tire replaced already working on number 2. First one not sure what the problem was, but this tire is having problems holding air. It'll hold air for about 9 hours then the gauge on inside of car comes in saying low tire pressure.
