“Sunday, June 25, when I was driving the car on the road, the engine shut off and the car stopped running. 3 warning lights show on screen: engine light; 48v Battery Service Required; 12v Battery service required. I used the break to park the car on the roadside after that.

What component or system failed or malfunctioned, and is it available for inspection upon request? …”

NHTSA complaint #11529864, filed 2023-07

“DIGITAL LIGHT low beam inadequate distance for safe driving on unlit roadway. Low beam has unnecessary blacked out areas causing distraction. Low beams too low, especially driving down hills. Adaptive high beams revert to low beam without any apparent light to trigger camera/sensor. Dealer states they are all the same, nothing they can do, call MB USA. MB USA gave me a case number but do no seem interested in solving the issue”
