On [XXX] I went out and started my car and it said. Power steering was my function so I turned it off and tried it again. And it said the same thing. Power steering malfunction read the owner's menu which I did is said if you can steal it. Drive it to the nearest dealership. You can't park it Well, it was already parked in my driveway. So on June 13th. I had a toll to Feldmann Import in Bloomington MN I hate to think of what would happen if I was driving. Could it cause an accident? They confirmed that it was a problem with the stirring call at first I thought it was a leak. Turns it off that This is electrical steroid. The electronics on this during column went out. The report said it was no can message was received from the unit in 68. VS steering control unit. There was no warning that the power Stern was going to go out. I did have a engine light on, but that was due because of my. Rare radar's being out. That's the best way I can explain it.

Rear 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

Panoramic Sunroof bonding and bolts loose causing constant horrific cracking/clanking sounds due to shifting of glass. Possible frame and airbag damage, possible glass falling, possible injury/accident/death. Can cause issues with airbags deploying and water leaks. Mercedes mechanic said it's the worst case/noise he has heard in any Mercedes. Same make/year/model has been recalled in other plants. Also, walnut trim has faded tremendously.

The sub frame of this car is being replaced under a warranty extension due to severe rusting and separation creating an extremely unsafe driving condition. It was determined during inspection the rear brake lines were also corroded. This is also due to environmental exposure and substandard materials of construction. Many E classes of the W212 and prior have this concern but Mercedes is not covering the brake lines as part of this warranty. In fact they are charging up to $4000 to replace with the subframe already removed!! This is highly concerning as this is a safety concern that must be covered.

What component or system failed or malfunctioned, and is it available for inspection upon request? -- sure -- the hard brake line popped open when I used the stop-hold function at a stop light, twice... How was your safety or the safety of others put at risk? - brakes had to be pumped the (short - close) drive home Has the problem been reproduced or confirmed by a dealer or independent service center? -- independent service Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -- no Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -- not prior to the failure, right when it popped was when i got the "check your low brake fluid" msg

I 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!

Cluster showed inoperative malfunction on the interstate and car accelerator faulted to 2 mph. A Tractor trailer came close to hitting me. Pulled over. Police escorted off and was towed to dealer. They first installed a new gas pedal but did not work. Now they said it is the harness electrical wiring tans the plug connector to the accelerator pedal that needs replacement. There is a bulletin on this with model year 2016-2019 only. They should include 2015 model as well. Very dangerous that could be fatal or seriously injured. This I happened to. 2015 Mercedes E Class.

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.

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.
