Limited data: fewer than 30 complaints, so shares and indexes are unstable.
Complaints filed between 2024-03-11 and 2026-08-04. Median delay from incident to filing: 8 days.

What owners report
While driving on the highway with the panoramic sunroof open, the glass suddenly shattered, sounding like a gunshot or an explosion. Shards of glass flew into the vehicle and rained down on me, creating a very hazardous driving situation.
The vehicle appears to have experienced a braking system malfunction, possibly involving the brake-by-wire system, electronic stability control (ESC), or unintended acceleration event.
Dashboard reading incorrectly. Blackout screen while driving. Mileage incorrectly reading. Speed limit incorrectly reading while driving the Dashboard pick up the undercarriage camera. The electricity on the car keep popping up.
Driving a 2024 mercedes c300 on the florida turnpike in the left lane at 70 mph the engine suddenly slowed down. While the vehicle slowed in heavy traffic I was able to merge to the outside lane where it stopped.
While I am driving my car it will make a loud crackling sound then my screens go black and warning sounds go off! This is not normal and I read there are recalls but when I entered my vin# nothing came up.
