SUSPENSION, UNKNOWN OR OTHER
I own a 2014 Mercedes-Benz E350, 4matic. that yeah car has approximately 64,500 miles on it. I recently Took it in for service and was advised that the rear subframe has a whole rusted through on the left side. The dealers advice was to replace the rear subframe. I was advised that it is not presently a safety issue, but it was going to be a safety issue as the rust continued. I was dubious about this advice, so I took the vehicle to a second dealer, who also identified the rust issue in the same area. Both dealer representatives advised that they had seen these issues before with the 350 class, and that there had been many complaints about them. I am aware that MB has replaced subframes on this group of cars in Germany and in Canada already—this is a well-known issue. The repair will cost between 3,800-5,000, but my real concern is that the subframe will fail and cause injury or death before it can be repaired. I do not believe this to be ordinary wear and tear as the car is relatively young, and rust is a very controllable problem with current vehicle technology. I am concerned that the scope of this problem is widespread, as both dealer representatives said that they had seen many cars with this issue. It needs to be recalled and repaired before people are injured or die.

FUEL/PROPULSION SYSTEM
Very strong gas smell enters the cabin and surrounding exterior of the car after fill up. Seems to be a very common problem with this model and follows the same issues with previous years that were filed with the NHTSA and ultimately needed to be repaired by MB. The problem appears to be with the components of the fuel tank immediately under the rear seat. I am at the point where this has become a very dangerous hazard that consumers should know that the manufacturer should address and that consumers should not have to pay for repairs.

SUSPENSION
I took my vehicle to Sun Mercedes for a Pennsylvania safety inspection on 14 Dec 2022. I was approached by the service representative that my vehicle failed inspection. There is a rust hole in the left rear sub-frame. He indicated this is common to Mercedes vehicles of my type/years. The location of rust is common and appears to stat from inside the frame. I saw many similar cases in my research. Also read that Mercedes covers the costs in some of the cases, specifically in United Kingdom and other countries. Here is ink to service video: http://smcipa.mkvwa43.com/p/thwROZ.html

SEAT BELTS, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
What component or system failed or malfunctioned, and is it available for inspection upon request? Automatic Emergency Braking / Selt Belt Pretensioner. Car can be inspected at dealer during a scheduled service if needed. How was your safety or the safety of others put at risk? I was driving on a local road (paved, no painted road markings, some small cracks/pot holes but all minor) that I frequently drive without issue. This time as I was coming out of a minor left-hand curve and about 30 meters from a slightly sharper right hand turn the Automatic Emergency Braking warning light activated, as well as the warning alarm, and the Seal Belt Pretensioner engaged and yanked me (driving) back (as it would if the vehicle was preparing for a collision. However, the vehicle never activated the brakes to slow the vehicle and the warning light and alarm deactivated and the seat belt released the tension. There were no vehicles coming from the other direction, no animals or pedestrians in sight. There is a utility pole located about 2-3ft off the right side of the road near this area. I've now had this occur two more times (three total) in the same location driving in the same direction. Twice I was the only occupant, and once there were two occupants, one in the driver's seat and one in the passenger seat (the Seat Belt Pretensioner activated for both occupants). Safety Issue: Automatic Emergency Braking System activating unexpectedly and unnecessarily. When Automatic Emergency Braking System is activated the Seat Belt Pretensioner activates and forcefully restrains the occupant (as I assume it should the vehicle expects a collision or harsh braking). This is very surprising and distracting for the driver (and in one instance also a passenger, who afterwards said they remarked they felt like it almost gave them a heart attack). This can lead to an accident given the unexpectedness. Additionally, the brakes never engaged or slowed the vehicle in any of the three instances.

FUEL/PROPULSION SYSTEM
I recently started smelling gas in my car after refueling. I was told by my mechanic that Mercedes was replacing fuel pumps and fuel tanks free of charge . Mercedes Benz customer care has advised this isn't so. This is an expensive repair and I am hoping Mercedes Benz can cover the cost of this repair and if not, offer substantial assistance.

ENGINE
We just purchased a 2006 Mercedes for our teenage sons and had a dealer look at it before we purchased it. They told us there were a couple of codes that were worth watching but that it wasn’t anything significant right now. After the car started jerking and shaking while driving it, we brought it in to dealership where they told us it had a common code for Mercedes in this timeframe P0016. Repair estimate is nearly $5000 to replace timing chain and balance shaft, or a new engine which would be roughly the same. After researching on my own upon being told this code, I found all of the information about the class action lawsuit and settlement, which of course we are too late to be a part of. The dealer said there is a potential that the car could just seize up at some point, so I don’t want my young sons to be out on the road when that happens. I am very frustrated and upset that this wasn’t a recall since it apparently affected a huge amount of vehicles manufactured within this time frame. There is a specific list of engines with known issues and ours is among them. Mercedes Benz should be held responsible for making this right because it was definitely a quality issue. Now we are stuck with an unsafe vehicle, or a massive expense due to defect.

STRUCTURE:BODY
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.

SERVICE BRAKES
The car lost the brakes as I was driving. This was very sudden and there was no prior sensor indication. Upon inspection, it was discovered that the brake line broke and leaked the brake fluid as I was driving, causing the car to loose braking ability. Inspection of the brake line also showed severe rust in multiple parts of the brake line.

Rear sub-frame is starting to rust/corrode. Understand from my repair shop that similar problems have been identified in other models using same rear subframe (W204 2008-2014 C-Class). Failure of the rear subframe may result in tire detachment and possible rupture of the fuel tank by metal fragments (per the repair shop).
