While on the freeway, going approximately 70 mph, the vehicles onboard cameras all failed and I got a warning that said “camera dirty/unavailable/traffic sign assist currently unavailable”. Because of this failure, I almost crashed the car in Front of me. I cleaned all the cameras. The message continues to appear. The dealer said “it’s a known malfunction with this particular model, based on the chip shortage, during Covid”. My car has 57000 miles and apparently several owners of this model, are experiencing the same issue. Dealer wants to charge $1,800.00 to fix a vehicle safety feature, that shouldn’t fail this soon.

Every Mercedes Benz manufactured in 2021 has a defective hood lens which prevents the adaptive driver assistance system from working properly. You can have it on and it will work intermittently which can easily cause a major crash. Mercedes Benz says the part is not available in USA or Germany. Every Mercedes is affected. I’ve been waiting over 2 months for the part. My brother, who owns the same car, has been waiting over one month. It’s a major problem because the car is suppose to self drive on the highway and it’s not staying in lane because of this defective hood lens. Hey [XXX] , I apologize for the inconvenience. There have been a few S classes with a similar message to yours. We have to order the camera lens hoods for your vehicle, but they are in back order. We don't have one in stock in the USA or Germany. I could have you stop by the dealership and clean the camera lens hood to temporarily remove the message on the dashboard. I can also order the part while the vehicle is here, and we would have to wait a few months for the part to arrive. When do you have time to stop by the dealership for a few hours? --Karen Hubschmitt - Mercedes-Benz of Brooklyn Sent from my iPhone INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving on highway at about 50 mph when the brakes suddenly slammed on and brought car to a sudden, near stop. The stop was so sudden our seatbelts engaged and we thought we were struck in the rear by another car. Electrical module issues that cause battery to drain while vehicle is turned off have been ongoing since I purchased the car in October, 2021. Car has been in for service related to this problem 6 times and for over 60 days.
