NHTSA complaint: 2021 MERCEDES-BENZ S 580 — ELECTRICAL SYSTEM
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.
