NHTSA complaint 11669739Rear brake lines rusted out on top of rear subframe which is rusting out and caused immediate brake failure . Our lives and the lives of other were at risk because we were driving on highway and suddenly brakes went to floor and had complete loss of brakes There were no prior warnings no way to prevent this ...i see there is a recall on the subframe but not on the brake lines even though ive now read of this happening to many people

NHTSA complaint 11557862crankcase ventilation valve continues to fail. I have had it replaced twice in 3 months.
NHTSA complaint 11549127I was driving the car and when applied the breaks noticed that they weren’t working. It was close to be an accident with the car in front of mine, but I was able to maneuver the car. When I stopped noticed that the break fluid container was almost empty and the fluid was leaking under the car. I brought the car to the Mercedes Benz dealership and they said that it was “normal corrosion” that caused the break lines to be totally rusted and leak. They also mentioned that “it was pretty common to happen in those cars during summer”. I had no option but to pay several thousand dollars for the replacement of the rusted and corroded brake lines. It is clear that Mercedes Benz doesn’t care about the safety of the passengers, and even worse, profiting from a defect in the materials that they use for the brake lines. Someone should make Mercedes-Benz recall the cars affected and replace the defective brake lines, free of cost for the owner. Passenger’s safety is not a business!

NHTSA complaint 11500927My 2015 E350 with only 40,000 miles was diagnosed to have a rotted and detached rear sub frame . Seems to be a common problem because of defective metal used by the manufacturer. There seems to be a lot of others with same issue I found on the internet . While Mercedes’ Benz has no recall as of yet. While driving on the highway , while at 50 to 60 mph. The car would sway and feel like it was sliding . After hitting the brakes the car would pull drastically to one side . After inspection at my Mercedes Benz dealership they told me that it is completely rotted and broke apart, this is a life safety accident since it could disconnect and hit gas tank and rip apart brake lines. The rear axle would shift and possibly fall out. While driving this car it put my family in complete danger . There were no signs , warning lights etc . That could have made me aware of the severe situation.
NHTSA complaint 11495964The rear subframe of the car (MB E350, 2015 with 81,000 miles) is completely rusted/corroded through creating an unsafe situation where the car pulled left on braking with resultant loss of control of the vehicle as it spun out. The brake lines are adjacent and are also currently being inspected by MB Open Road Service [XXX] in Bridgewater, NJ. It is a miracle we (my three grandchildren, my husband, and/or I) were not involved in a tragic accident. This manufacturing component failure has been widely reported in the USA and worldwide for years with recalls in other countries, but not yet in the USA. I also reported this by phone to MBUSA, but have yet to receive any information or confirmation of the issue in writing. As you can see from the photo (courtesy of Denson's Auto Repair who has seen this issue before), the subframe is completely corroded through. There were no warning lights and I get my vehicle serviced at the dealer every year. The vehicle was thoroughly inspected in January of 2022 for an A type service and no mention was made to me at that time about this dangerous corrosion. This is a material failure and not simply a result of harsh NJ winters with salted roads. I have never seen subframe corrosion failure in any of my cars with far more years and miles on them.
