Serious fold-down seat issue
OK, let's look at another absolutely crazy case of engineering getting in the way of common sense . . . OR . . . MBZ failure to admit a serious defect.
If you fold down the passenger side rear seat, as expected the passenger front seat moves forward a bit and leans forward a bunch. Then, when the rear seat is all the way down, the passenger front seat is FROZEN, making it completely unusable by a front seat passenger, in spite of the Owner's Manual saying you can then move the seat and seatback back (page 278).
On the driver side, the front seat is NOT frozen, and behaves as the Owner's Manual says it should . . . you can move it back.
This has been tested in multiple cars, 550 and 350, and behaves that way in all of them.
In other words, a feature we paid big money for and, in my case, really needed, is completely useless if we have a passenger.
My local dealer, and apparently MBZ, says this is as designed, a ludicrous assertion.
Has anybody found a solution to this issue, or even noticed it?

Can you move your front seat with the rear seat back unlatched? If so, what was the build date of your car?

I don't see how there would be a difference between E550's and E350's.
It all depends on where the front seat is positioned to begin with.
One thing is good news, someone can ride in the seat in my car with the rear seat down because you can move the seat back to a point. With our 2008 E350, not even my wife could ride in the front seat with the rear seat back unlatched.
MCF, do you have memeory seats?
I really pressed my dealer on this issue, after techs said it operates (locks the passenger seat) normally.
I just got a call from my dealer. They have a software flash to fix the problem!!!! And they tried it out on a new car and it works!
I go in for 10,000 in a few weeks and I'll get it done then.
The moral: local service people might say that some things are normal operation because there is no fix and no information from MBZ. And that's what they are trained to say. But we need to keep after them to pick up MBZ fixes when they occur, 'cause other people are comlaining, too, and eventually stuff can get to the people who have responsibility.

My car 2011 E350 built June 2010. Has the same issue but also found that it works correctly too.
When I go to my car in the morning and before anything else:
1. open the trunk
2. pull the passenger side rear seat back release in the trunk, which makes the front passenger seat back to move forward
3. open the right rear door (and car unlocks at the same time, it is a P2)
4. fold the seat back down
5. open front passenger door and voila, the passenger seat back moves back in correct position either with the seat back button or just holding down the memory button.
Above happens every time. After I drive the car or use the key remote it does not work any more but next morning after car has been sitting over night I can repeat this same.
It seems it could be the same way in all of these cars with the problem.
Take a video of this behavior and take to your dealer and ask why the German car engineers think it needs to work differently before you drive it in the morning. That is what I will do. Have the video already but have not had time to make a service visit yet.
