The contact owns a 2015 Mercedes-Benz E400. The contact stated that while the vehicle was parked, the steering wheel material was peeling off. Additionally, the driver’s and passenger’s side window buttons were peeling. The contact stated that the dashboard was bubbling. The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 76,000.

The 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.

My 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.
