Bad Front Passenger Seat Controller
I have the multi-contour seats, and I could adjust the lumbar size and position as well as the side bolsters using the COMMAND system, but the settings would just revert to zero the moment they were set.
The dealer service department has to keep it overnight since they didn't have the part in stock and they gave me a little C-class to drive. Boy, does it make me appreciate my ML! Feels like I'm driving a go-cart.
Overall, I'm disappointed in these seats. I was expecting the bottoms could be extended out further to support the underside of the thigh, and for the side bolsters to wrap around more, like with my old X5. But in contrast, the adjustments are meager in their extent. So, I don't feel as 'planted' or snug as I did in the X5.....I still feel like I'm sitting on top of the seat, rather than fully in it. And this affects how I drive, making it not as fun as my X5 when it comes to maneuvering corners and curves. So, not only do I feel I wasted money this option, but also on the expensive ACTIVE Curve system which I can't fully enjoy as a result.
To be sure, the fact that I'm 6'-2" and about 280Ibs probably doesn't help....and, admittedly, I could stand to loose a few... but my X5's seats didn't seem to mind.
And I doubled check that once the seat is all the way down, you can't tilt the front of the seat up, which would give more under-leg support....so this part is just plain frustrating.
The new model of the X5 is coming out sometime this year. If they've been successful in improving the ride quality as rumored they'd do by adding an AIRMATIC-like suspension and comfort settings, I might be tempted to ditch this ML and return to the Dark Side.

And here I thought by going to the MB dealer's service department, rather than to my local independent MB shop, I would get better, more knowledgeable and skilled service. HA! These guys are clueless!
But to be sure, it can be done if the seat bottom isn't all the way down.
Could you try this for me please? Put your seat all the way down and back. Then try to tilt the seat bottom back, so that the front comes up while leaving the back down...so it starts to pinch you in the seat a little. If you can do that, then I'm going to have to have that checked out, too.
The GT rides a little higher than the normal sedan, as you know....which is why I considered it. I don't like feeling dwarfed by the cars around me, and rather have a more commanding view of the road.
They say that with the GT, you either love or hate the shape of it. I like it's unique look. Around SoCal, MLs are, as they say, 'belly-button' cars...everyone and their Soccer Mom has one. The GT, on the other hand, is a relatively rare bird....and that alone makes it pretty cool.
I wasn't impressed with the the ride...expecting it to be more isolating from the roughness of the road, especially with its comfort setting...but then, again, it's a BMW. Seems nobody has figured out how to marry the amazing handling of a BMW with the ultra smooth ride of a Mercedes. So, if you want a super fun car to drive, it has to be an BMW. If you are willing to sacrifice fun for more comfort, it's a Mercedes. Sure, there are other makes to consider, but that's another conversation all together.
But in the end, it was all the unique safety features of the W166 that sold me on my ML550....and, especially vs the GT, the extra height. But if I could afford a couple extra cars in my stable, that 550 GT would be one of them, for sure.

No, I haven't...and it's been a long time since I've been in one...and it was only as a passenger while driving round Hong Kong years ago. So, I don't remember how it handled.
I would expect the ride to be amazing, but can it do 'corner flat?'

Believe it or not, now on Day FIVE, and the dealer still has my ML, unable to program the seat controller properly. They point the finger at "MB in New Jersey," who is reportedly giving them instructions that just don't work.
I'm beginning to wonder if the dealer service department is truly the problem here. I'm seriously considering just taking it back as-is and being it to another dealer for a 'second opinion.' Perhaps it would then 'miraculously' be fixed.
Meanwhile, I traded in the C250 loaner for GKL, which is A LOT better. At least I don't feel like I'm driving a tin can like I did with the C250. That C250 is an embarrassment and abomination for all I believe Mercedes Benz represents in terms of quality of ride, luxury and performance.

Dealer service dept. still has my ML! They can't figure out what is wrong that is stopping them from programing the front passenger seat controller. They say it will 'not wake up.' If they swap it to the driver's seat, it works fine. They say MB's tech support center in New Jersey went as far as to hook up their computers directly to my car as it sat in the shop in SoCal, and they tried and tried but couldn't figure out how to fix the problem. Now, they say, the problem is being sent all the way back to Germany for resolution. Meanwhile, they've given me a GLK to drive, which isn't bad, but just doesn't have all the bells and whistles that I've been spoiled with with my ML, like GPS, Blinds Spot Assist, SAT Radio, etc. I also hit someone the other day because they were in my blind spot....I think that blind spot warning feature is the most valuable of all.
Anyway, they'll tell me more on Monday. Hard to believe it will be eight days in the shop by then. I asked my service rep if MB will try to make up for this in some way. He said he's known of MB paying a lease payment. But since I'm buying it, I know this would be a little different.

Believe it or not, my ML is still in the shop. They finally figure out how to update the software, as was provided by MB New Jersey. But then discovered one of the feeding air hoses was apparently blocked, since the pump would stop as if the air badder in the mufti-contour seat was full. So, today they've been disassembling the seat to figure out where the blockage might be.
Thank goodness this is all happening while it's under warranty...and it sure is an argument for getting the extended warranty.
As a further note, I have only managed to go into a three wheel slide once, while on ice The ML just doesn't skid that well on ice, and that is great!
I immediately drive back around to the service department...and they service manager and his crew are all clueless. They say it was all working fine. Now they think it is the air pump in the back and need to order this part...which should arrive by tomorrow afternoon.
I wished yelling and screaming could make a difference. But I can only shake my head. Seems I am at their mercy and without any recourse, but to let them keep trying.
So, off I drove with another loaner.

I go to pick up the ML on Friday. I get in and sure enough, it is still not working correctly. The COMMAND system will not remember the setting for the bottom of the drivers seat. It just snaps back to zero the moment I would set it. You would think the dealer would have thoroughly tested this, especially given how they failed to do this before.
Luckily, It occurs to me that maybe if I chose 'reset,' it might shake things up enough that it would start to remember. At first that didn't work, but then a service manager, who was about to take the car back in and give me yet another loaner, suggested that I turn the car off and on after doing the reset. And sure enough, that worked. It would finally remember the setting.
All I can do at this point is shake my head and think, 'never again.' This dealer is far too incompetent, careless or both to continue to get my business.

I had my MB lemon lawed. At the hearing MB based their whole case on the computer saying everything was OK. Once the board inspected the vehicle they ruled in my favor. My guess is that MB is still shaking their heads on this one.
After my short experience with MB's service, or lack of, I will NEVER purchase another MB again.
Your post also explains why every time I get in the car I have to reset the multi-contour settings. I don't use it that often so I haven't bothered to read the owner's manual to find out what it's programmed to do. However since there is a "RESET" option I should have realized that the settings should remain unil you presss RESET.
I think I'll drive it for a few more weeks and see if there are any other issues. What a PIA.
I'll check the passenger side today and then call for an appointment.
I'll also copy some of these posts to show them what the O.P. went through - maybe it will save me some time.



Also agree they are not as good as BMW sports seats.......they are the best ever.
