Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Car has software issue putting drivers at risk until the update is provided. Response to problem from manufacturer is to drive the car or wait until such time as a solution is developed. this is the 3 issue in less than a year the car's fuel uptake system is interrupted putting drivers at risk when pulling out into traffic or needing normal acceleration expected from a normally functioning car. How long will Mercedes get away with this before someone is killed”
NHTSA complaint #11623589, filed 2024-11“While driving on highway at 75 mph, the car began slowing down and an alert on the screen said Stop. Switch off vehicle . Then the alert on the screen showed that the 48 volt system needed to be recharged. The car would not start and had to be towed to the dealership. The dealership says the car was out of gas, but the gauges did not indicated that the fuel was empty, so they will reset all of the sensors, but they still do not know why the car turned off and could not be restarted. They are checking the software because they cannot find anything wrong.”
