Has anyone had their seats reposition themselves overnight?


Solved sorta; Never having used rear seat fold down option before, I hid a present in the car, had to fold down seats not noticing the front had moved as I didn't need the car for several days.

If the operation of folding rear setbacks down for cargo room moves the front seat out of way, shouldn't returning the rear seat to the locked up position return front seats to previous condition? No person could safely operate any vehicle with seats in this position.

Are the key fobs linked to seat position? Did someone else's keyfob with their settings close or open the vehicle?

Other than above, check for

No, I believe I have that turned off and the second key remains in the house for a backup, I'm the only driver. The seats did not move to a memory location, both front seats raised all the way up, all the way forward, headrests all the way up, and the seat backs tilted all the way forward or straight up. Where the seats are not ever readjusted as they are perfect. I was concerned as both seats are separated by individual modules only thing that connects them should be power source and memory buttons.

We did have a pretty bad lightning storm. My neighbor's truck is bad broken today as well, all electronics are inoperable and he had it towed to dealer. My other neighbor has the residential heat and air, the unit in attic quit during storm. I'm wondering if this was affected by that, I didn't know about the others till I walked out front just now and saw the A/C van a nt the tow truck.

Only once I have had to reset the seats, it was over a weekend. Didnt touch the car for a few days and when going to work in morning the driver seat was repositioned. Now only reason I can think of is that I pressed the #2 saved spot when I was getting out originally and it had enough time to move the seat. Thats the only thing I can think of since no one else touched the car other then me.

I agree with that, but both seats were in the extreme position noted in a later post. I later today locked the car with front windows down, waited 20 min. for all modules to be completely asleep and found power to seats still available even with key well beyond the 3 feet threshold.

This is what my seats do when I fold rear seat.
Meaning single switch malfunction could do it.

Rickman30

You mean to tell me I did this when I folded the rear seats down to hide a birthday present. Cool.

PeterUbers

That's a cool feature - so long as no one is sitting in the front seats when you fold the rear down

I don't know but suspect that the seats have sensors in them to detect occupancy. Isn't there something that says the passenger airbag is off?

Seat memory may be at play here...

When driver#1 stores it's prefered settings in the solderless door control unit (aka DCU) they are recalled when unlocking car with #1 key.

If driver#2 key is used, #2 memory settings are retrieved automagically.

Rickman30

No doubt that might be the case had both seats not been all way forward with backs all the way forward and both keys were in use with two drivers in memory.

But, as stated earlier, second key is never used I'm the only driver. Seats were all the way forward, the backs tilted all the way forward, and as I have discovered, previously had folded back seats down.

Now the question is, if this is normal operation of folding rear seat backs down to allow larger cargo, why didn't seats return to previous settings after seats were returned to their upright locked position?

PeterUbers

See if you can replicate this

Rickman30

Yes, I did. And it does. I'm wondering all this technology, no one thought to have the seats return to previous position after stowing the rear seats back.

If I was a few pounds more, or drank a few beers everyday with a gut to prove it, getting in the car like this with your stomach pinned to the steering wheel might be an issue.

You can just push the #1 setting or which ever number you programmed your preference too while the door is open. Dont have to sit down to do it. Unless ofcourse your already committed and dont realize quick enough like I have done with my wifes kia (she is 5'1 Im 6'2 with few extra beer pounds that you speak of).

That's something I didn't know existed . Another cool Mercedes-Benz feature
I have driven many cars with folded seats but none of them have had a pleasant over engineered surprise

Rickman30

Sure, it's like getting a little bondage time in while enjoying you Benz

Rickman30

Yes, like you say, if you're committed. Like a mini trip to Helga's House of Pain.

So did you ever figure this out? I had the same thing happened to me after a tint install

Folding rear seat down will move front seat to front and tilt seat back up to make room for the rear seat. This actually happens when the latch is pulled in the trunk.

The driver's seat can be moved back to wherever you want to, but the passenger seat cannot. I'm talking about my first 2011 E350 and current 2010 E550. Both cars I had coding changed at the dealer so the passenger seat can also be moved to position you can actually sit on while rear seat back is down.

Totally overengineered useless feature as the seat must be manually fold down and who ever does it will see if front seat must be moved, which it does not unless a long person uses the front seat.

I just recently saw a video of this feature on an older model, I think W211, which had the rear seat bottom fold forward. For those the front seat needs to move forward. I just don't know how you drive the car with it as the seat position is unusable for driving the car. I think MB forgot to remove this front seat move when they removed the seat bottom fold.
