Rear subframe corrosion and failure. Based on my queries this apparently a common issue. I am adding my report to add weight to this common issue. Vehicle is approximately 13 years old, is in good condition, and has not suffered any accidents affecting the rear subframe. Overall only minimal rust or corrosion is found during a visual inspection while on a lift. This vehicle has passed annual inspections as required by Virginia state law. The rear subframe has rusted from the inside. This corrosion was not visible from the outside, which is why it was not found in the annual inspections. Due only to this internal corrosion, the left-hand (driver) side of the rear subframe has broken loose where the rear wheel's control arm is attached. This removes one of the rear wheel's primary attachment points, making the vehicle unsafe to drive.

VISIBILITY/WIPER, ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
The entire driver instrument panel screen went blank, after going blank and coming back on a few times while driving. This is EXTREMELY dangerous. Now, the driver cannot see the speed, odo, fuel gauge, indicators or anything at all. I hope you please investigate and initiate a campaign and get this resolved from Mercedes.

SERVICE BRAKES
Rear brake hard lines are corroded and leaking. Loss of rear brakes and fluid while driving. Rear subframe corrosion is being addressed by recall/warranty extension but this coverage has not been extended to the premature failure of brake lines. The rest of the car is not rusted or corroded, only rear brake lines and recalled rear subframe are rusted and corroded. Attached photos show the condition of brake lines and additional photo shows the rest of the car in a rust free condition.

STRUCTURE:BODY
I received a letter from Mercedes-Benz USA LLC located at 1 Mercedes-Benz drive Sandy springs Georgia 30328 phone number 800-367-6372. This letter advised me of the extension of warranty coverage on the rear subframe of my vehicle to 20 years with unlimited mileage cover. I call my local Mercedes dealership where I purchased the vehicle to inquire about the severity of this problem. I specifically inquired as to whether this presented a safety concern or not. I was advised that the rear sub frame is the mechanism that holds the rear end of the car to the frame which if deteriorated enough would cause the rear end to separate from the frame resulting in problems with maneuvering the vehicle. Once I was advised of this I requested an appointment to go in and have the rear sub frame inspected to see exactly where the deterioration stands on this vehicle. In my opinion this is a definite safety concern and should have been classified as a recall rather than just a warranty extension. I was granted an appointment to have my subframe inspected tomorrow afternoon for which I specifically requested whether I would be charged or not and was advised I would not. I request that this be looked into by your agency as I do consider this a real safety factor. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES
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!

SERVICE BRAKES
My car had a pool of brake fluid under the car and when I turned it on, it said the brake fluid was low. When I went to check the reservoir it was empty. The underpanels were removed and the brake lines were rotted out in several areas. I was shocked because my car is in mint condition and I have always avoided taking it out when the roads are salted in the winter. I am lucky this happened when the car was parked. This has never happened to the cars in my family which were never treated with as much care.

STEERING
While driving on a local road, my wife lost control over the steering wheel of our 2014 Mercedes-Benz (MB) E350 sedan (the instrumental panel showed "Power Steering Malfunction: see attached photo)". It was a very dangerous situation, but she somehow managed to find a place to pull over and call me. It could've been much more dangerous if this occurred on highway. We found some information about the Power Steering Failure recall and our 2014 E350 was included as an affected car. Here is the website with that information: https://repairpal.com/recall/16V899000 However, our local Mercedes Dealer checked and found our car was not included in the recall list. The problem we encountered is identical to the nature of the recall, so we don't understand why our car is not included. The dealer recommended me to call MB Customer Service, which recommended me to contact NHTSA, so I'm contacting it. I hope you help us drive safely by adding MB 2014 MB E350 into the recall list. We need the car desperately as soon as possible. Thank you in advance for your help.

STEERING, WHEELS
Two problems: 1. Axel grease found on carport cement multiple times. Mercedes refuses to look at the wheel bearings or axel. 2. Automatic steering wheel adjustment makes clunking noise. Mercedes refuses to replace until it fails. Both of those items should be covered under warranty which I think is why they refuse to fix them.

SERVICE BRAKES, VEHICLE SPEED CONTROL, STEERING
I was driving my husband's 2016 E350 at 45 mph when the car accelerated. I attempted to control the speed by braking but the brake did not respond well. The steering wheel was also loose. The car sped up and turned left to the opposite side of the road, crossed the two lanes and hit the fence followed by a tree. The car was totaled, and the tree broke down at its branches. I survived the crush with two fractures on my back and on my left thumb.
