The liftgate on this car is faulty. There are hundreds of reports online that I found when it happened to me, which has been several times now. The liftgate has a sensor that is activated by your foot, but when you are inside the hatch it will trigger and close on you. There is no sensor to stop it from falling and it traps you inside and has hit me on the head, bruised my shoulders and back and I have fallen from being hit by it. I have reported it to Mercedes several times and asked them to at least cover the sensor and they say it's not possible. This is dangerous and it's going to seriously injure or kill somebody younger or more feeble.

Vehicle experiences a severe, abrupt jerk/jolt during deceleration around the 5th-to-4th gear downshift. The issue occurs consistently when slowing down. Dealership verified the condition on Repair Order #1906625 and confirmed a transmission flaw. Dealer stated software is required from the manufacturer with no ETA for release. The abrupt deceleration creates unexpected cabin jolting during normal traffic slowing.

All of the screens in the car failed to start. They remained black while the car was running. Turning the car off did nothing. Drove to a parking lot, turned the car off, got out, locked the car, waited 5 minutes and it still didn't come back. Had to do a reboot by holding the system power button for 10 seconds. This has occurred 3x in 9,200 miles.
