3rd row seat issues
There are lids that should protect things getting under there, but they ended up there anyway. Although this didn't prevent the seat from flushing, it could be worth checking. BTW, mine has worked fine all the time.
time to take it to your highly trained, very well versed Authorized Mercedes-Benz Service Center.
Odd thing, try holding down both the up and down together for a couple of secs and let go, then try them out. It could reset the "malfunction." Reason I say this tactic is because in our 04 E320, the driving dynamic didn't work and the service advisor held down two of the buttons, shut the car down and started it back up and it was fine ever after.
