Rotted rear subframe
dave@castellini.co.uk
it was garaged and stored for the winter. There is no corrosion anywhere on the vehicle except the rear driver's side carrier arm as others have noted in the thread. I would
expect rot elsewhere if it were salt in general. In my opinion, this is a design issue. Since Canada has administered a recall I assume it is a valid defect. Lucky the rot is not extensive and my mechanic
said it is still drivable. I have been waiting for parts for 3 months and they are still on backorder. The local Mercedes dealer indicated the same but I assume they are handling their customers first before selling to repair shops. Please log a complaint with the National Highway Traffic Safety Administration (see below). I have seen a number of complaints logged already. If there isn't a recall I hope there is a class action lawsuit. Maybe we should start one?

I just experienced the same issue with my 2011 C300 which has approx 119k miles.
My son was away at college and started complaining a couple of months ago about the car leaking brake fluid. At that time he took it to a local mechanic near school who replaced the brake line. Fast forward to last week and my son (now home for Christmas break) complained about the rear of the car swaying when coming to an abrupt stop.
I had a shop close to me that specializes in German vehicles take a look at my car and was shocked when they showed me the rear subframe (see attached photo). I was even more alarmed to learn that over the past couple of months this the same shop has replaced the subframe in 3 to 4 Benzs. This is a serious issue that could lead to a catastrophic accident.
I spoke to someone (Laura) at MB corporate office today and was informed that there aren’t any current safety recalls for subframes. She also took my complaint but said she really couldn’t escalate it unless my car had been involved in an accident and I had it diagnosed at a Mercedes dealership. Needless to say I will be writing a safety complaint to the NHTSA shortly! I’m lucky that it didn’t take my son getting into a serious accident for me to uncover the problem.
It is ironic that MB escalation support person responded on Dev 14th to my case reported on Oct 13th after 2 months asking me to take the car to the dealer to inspect and repair. Is this a trick MB play to check with customers can wait for 2 months to repair their car? or is it to brush off the issue just in case customer get the subframe issue fixed on their own cost? I have only one car and dealer said subframes are in backlog will take months to get the parts so they won't provide loaner car either. I had independent MB certified mechanic fix the car who bought the parts from MB germany warehouse although it took little more than 2 weeks till then I had to rent a car on my own expense. Complaint was already launched to NHTSA. Also there is a litigation in process so folks those who have subframe issue or you have that fixed please keep the receipts to get it reimbursed as MB USA plan to make a recall on subframe issue. Also make sure to report complaint to NHTSA as well. See below response from MB support team,============================================= ===============================
We understand your shock and frustration as we wish there could be more that we can handle on our end. The statements made were not to alarm you and we do apologize for the delayed response.
To clarify, There are no recalls attached to your Vehicle Identification Number. However, I see you have mentioned that there is currently a recall in other places excluding the U.S., so we can help get this for review for a potential recall. While we make contact, it is necessary that you report this subframe issue to the National Highway Traffic Safety Administration to boost the process for review. Also If you are seeking reimbursement for the subframe, the receipts would be submitted to the Dealership to build the case, but this may only be possible when the recall is in place. Below will be the contact information for NHTSA.

I have been in contact with a lawfirm in Chicago who is also researching this issue. They are looking to speak with people who have already experienced this and have paid for the repairs to learn more about the situation.
If you have paid for the repairs for a rusted-through rear subframe on your vehicle and are willing to speak to an attorney to provide information for their research, please message me and I will send you contact information so you can reach out to them.
I have a 2015 E-class which has not yet had this issue occur, but I don't want to experience it and, quite frankly, shouldn't, especially when these vehicles which are suffering from the problem are not decades old.
Hopefully we can get MB to replace these for free in the US or, even better, issue a recall.
Mike
I am happy to speak to this attorney. I experienced the sub-frame failure and paid $5,200 to fix it. cbuck12345@aol.com
I sure do hope y'all get this situated. It should be free of charge from MB.
In the meantime, ill look elsewhere for a used luxury sedan
