F'ing window regulators - anyone else have this issue?
I've had three previous window regulator failures over the past five years, possibly motors too but don't remember specifically. Those were under warranty so no big deal but now that I'm having to spend $2400 to make my windows work on a car that has what would only be 18 months worth of normal mileage on it, it's getting frustrating.
I've found references to other people having the same issue with these. Has anyone gotten MB to do anything about it post-warranty?
MB has come up with revised regulator.
I don't know of anyone getting MB to replace after the warranty.
It looks as the new version is working fine.

Is there a Bulletin on the regulator? If so, see above, it should have been fixed gratis.
I have found AMG is very eager to make their clients happy. Join the Private Lounge and perhaps the AMG folks will work with the regional rep to resolve the situation. For example, they helped me out with an alignment issue.

If the G55 had been taken in for regular service while under warranty and a Bulletin related repair was not made that was directly related to the complaint and the original owner was charged for a repair multiple times the MBUSA regional rep should be contacted. I have had recent personal contact with AMG managers who are very keen on customer satisfaction and brand excellence. Refreshing.
I do not know what the dealer situation is presently in So Cal or Tampa. In the NE I had cause to stop on a trip at a dealer (MB of Danbury) who insisted that I leave the AMG with them so they could perform Bulletins that the selling dealer had failed to perform. They kept their tech until 9pm and provided me with amenities that helped lighten up the situation! No charge!

I've yet to hear back from the service guy on whether he was able to get any concessions from MB, AMG, etc. on this; I won't be too happy if a $110k car that's barely used can't have known-defective regulators replaced post-warranty or otherwise. Makes me wonder what else will break. I'd hate to get rid of it too because I've done a ton of Kleeman mods and love the thing but I'm not going to let it turn into a money pit.

The service guys hands are tied, mostly they type something into their computer and the answer comes back ya or nay. That is why I would be prepared to take it to the rep. Join the AMG private lounge, you need your Vin and after you get a feel for etiquette reach out to the AMG folks.
Is it too late buy an extended warranty for future repairs. Usually there is a grace period.
No matter what the nomenclature, I would press the issue with the regional rep in writing after gathering and documenting the facts. AMG is refreshingly concerned about the brand IMHO. One AMG rep I spoke to mentioned Kleemann as a a modifier acceptable to AMG and was familiar with their German relationship. How this squares with the written Mb warranty is another topic.
What dealers are motivated by is well documented by members above and I would not expect them to go outside their motivation zone.

Warranty ran out after three years, I bought it about five years ago.

Follow up with a letter and thank them, I suppose.
Where do I find the private lounge?
Use your search engine I do not have URL handy

ago.Well, at least now that I've replaced three of the four in the past three months, I'll be covered on the 12 month part warranty on three windows until next summer.
Pretty likely I won't be purchasing a future AMG.

It looks like the fronts may come with an updated motor too but I shall report back. If you have a G out of warranty you need to find a specialist indie and use a Sponsor for parts. Overall I save 30-50% over what the OP using dealer reported.
Why didn't they use screws instead of rivets? The play is real Achilles heel.
Make sure you get the Rivets if you or your indie puts them in.

Thanks to Sponsor www.mymercedesparts.com for info and great prices and service!

Please reread the quote below about a caution removing the old single member window clamp. What a cludge!
Forget what I said about rivets I was misinformed. My bad!
I'm sending the old parts to the MBusa president for kicks!

The front is a real improvement it has dual lifts instead of the single lift but it is a pain to take off the long clamp on the window glass. Be careful and take your time.

Get you VIN plug it into the Sponsor website and it comes up with integral motor, is my best guess. Questions call Jeff at the Sponsor but be careful about dealership issues, as I'm sure you will. If you speak to him tell him my tech and I are very happy with his service!

Don't waste $369 or more on an "OEM" regulator. These can be had for $99-$119 on any MB wholesale website. When you get your new regulator you need to lubricate it with spray lithium and multi-purpose grease, then install it. I promise they will last much longer than the rest of your vehicle if properly lubricated. I swapped out four of mine when I bought my G and they've worked perfectly ever since.
