What owners report
When loading groceries in my trunk, the door randomly closes on my head. The last time this door closed while we were loading, I tried stopping it with my hand, by holding it, so my spouse doesnt get smashed, and it will not stop at all.

My 2023 GLC300 suffered a severe, unprovoked emergency brake deployment in traffic, nearly causing a pileup. on [XXX]. The car has only 14,500 miles and has a chronic history of dangerous, unprovoked Active Brake Assist deployments.
I purchased a new Mercedes Benz GLC300 2023. Last month, my friend and I were driving on I75 in Florida when we heard what sounded like a loud boom or gunshot. We quickly discovered that my sunroof had exploded.
