Family and I were driving on the interstate and heard a loud bang (like a shotgun) followed by immediate glass everywhere. The panoramic sunroof exploded. We had to drive 4 hours like this - lucky we didn’t jerk the wheel on the interstate with the noise. Absolutely sickening that this is so prevalent and Mercedes won’t do anything about it.

I have taken it to my local …

My safety and the safety of others were put at risk because the vehicle requires constant steering correction to avoid drifting left, creating a danger of unintended lane departure and loss of control, which aligns with the steering‑related risks described in NHTSA Recall 21V990 / MBUSA …
