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.
1. Rear Hatch hands free system - closes unexpectedly while loading or unloading car without using feet to trigger system. Hatch will close down and trap driver in the rear, causing bruising on driver and requiring assistance to push hatch back up.
The contact owns a 2023 Mercedes-Benz GLC 300 4MATIC. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed; however, the brake pedal felt as if it had released, and the vehicle failed to stop as needed.
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.
