Brake lines are rusted and corroded. It appears that the rust may have spread from rust on the rear subframe. The rear subframe warranty was extended for premature rust and failure, but the brake lines are not covered. This could have led to a dangerous situation. I've never had a vehicles brake lines rust like this. They should also extend the warranty coverage to cover rusted brake lines.

Defect investigations
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

What 2014 Mercedes-Benz E250 owners say
Most recent owner complaints, unedited.
Purchased and installed OEM diesel fuel filter made by Mann part WK820/17 or 171103 on [XXX] and drove for 9500 miles. On [XXX] I checked fuel filter as I could smell diesel fuel near the car for the last 2 weeks. Fuel filter heating element/H2O sensor was cracked and seeping fuel once fuel pump was turned on. Unit is available for inspection Safety issue-leaking fuel No inspection by police, manufacturer. I did contact RM EUROPEAN Auto Parts in Colorado who sold the part and am waiting to hear back. No warning lamps or CEL illuminated, only the smell of fuel with top of filter and engine coated in diesel fuel. (Tried to upload photos but "Upload Files" button just goes blank.) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). The contact stated the fuel appears to be leaking from the electrical heating element. possibly where the rubber has split open.
Tl* the contact owns a 2014 mercedes benz e250. The contact stated that the driver's seat was covered with a synthetic material called mb tex. The material was torn. The contact had to place a cover over the seat to avoid being poked or cut by the material and to avoid making contact with the heating mechanisms within the seat. The contact contacted mercedes-benz of arlington located at 585 n glebe rd, arlington, va 22203 (703)525-2100, who acknowledged the failure however, there was no fix for the failure. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 170,000. The VIN was not available.
The power steering stopped functioning suddenly while driving and I was unable to make a turn except by substantial manual force. Fortunately I was not on a highway and at 20/25 MPH able to pull immediately off the road. The dealer repaired it and said that it was a computer system issue and that they were aware of it but had not notified customers. And apparently they haven't done so yet or notified the ntsb because nothing shows on this website. The occurred over 6 months ago so I am shocked that it hasn't been dealt with.
The car has a eco system which makes the engine stop when you come at complete stop to save fuel. When the incident happened, the car started with a huge jerk as if the gear box is broken. Now it is giving two difference messages: 1. Auxiliary battery malfunction 2. Pre-safe functions limited (see operator's manual) the car is jurking heavily. I took it to mercedes dealer in pleasanton, ca. The service agent asked me if I bought the vehicle from them. I told that I did by an s550 from them but not this one since they didn't have the specific feature which I needed hence I went to san jose mercedes benz who had the vehicle which had all the features of my choice. She then told me that it is pretty safe to drive and that they don't have time and slot to check the vehicle and I have to make an appointment to get it checked. I told them that "as long as it is safe to drive, I am not worried, however, to me it is quite unsafe". Due to this issue, I was parking the car in a parking lot of 76 gas station, the car engine stopped when I applied the break in the parking lot. I wanted to park it right so as I pull my feet from the break, the car jurked and hit the front guard from right side to the front parking (concrete stopper) stopper. I have to show it to the dealer during my appointment on wednesday.
My wife was at the final stage of parking the car ,means,slowing the car by pushing the break the car in the parking slot.when she was in position to stop the car suddenly got acceleration uncontrolled.to avoid hitting the car in front of her she turn wheel to the right and with max. Speed car jumped through the edges of the island with the tree .tree stopped the car and car and tree was destroy .she was distress.shock and till now has a nightmares.
I have a 2014 mercedes benz e250 diesel, I complained that the engine hesitates when trying to accelerate, I was told that the trans and engine has to get used to my driving habits,,,lol....it's still doing it, also the suspension on the 2014 is horrible u can feel every bump, crack, pot hole, I took it back to the dealer they said there is nothing wrong with the suspension, I was driving on I-95 hit a pot hole for the cost of this car and the benz reputation, it sound like I crashed into a wall and almost lost control of the vehicle, it felt like the front of the car fell off I had a 2006 eclass, and the 2014 is nothing like it, it's cheap, drives like a 50 year old car, don't buy it.
