The trunk safety release inside the trunk will not open the trunk. It is an electrical switch and not a cable pull release. If you get in the trunk and the battery is low, you cannot get out. There is not a passage between the rear seat and the trunk. There is not a manual release for the trunk. The only way to get inside is cutting through the trunk lid or deck.

Brake line corrosion and rear subframe corrosion.

The brake lines leaked fluid brakes started failing. Brought to a repair garage. Advised that subframe is cracked and completely corroded. Mercedes is covering the subframe but not the inferior brake lines which are failing.

Rear subframe snapped under hard braking on the highway and caused my to veer into leftmost lane. It was terrifying and a severe hazard on the highway. Had vehicle towed to my house. I lifted and inspected my car and found the rear subframe was rusted and a crack straight through. The rear brake lines were also severely corroded and are very close to failing. Front brake lines have no corrosion. It seems that the rear subframe and rear brake lines have the same anti rust coating which are clearly not sufficient.

Took car in for an oil change. Have been hearing some noises in the rear. Mechanic just called telling us the rear sub frame rusted out. We have had the car 6 years. It has never been in a flood. We live in new jersey, no where near the shore.

The rear subframe is corroded and needs to be replaces - there was no prior warning and the benz dealer stated this is something that only is evident to even the most highly trained mechanics once it is at the point of total failure. The rear brake lines are also corroded and the benz dealer will only pay for the subframe and not the very expensive rear brake line replacement which seems to be entirely related.

Dealership stated on 6/4/24 extensive rust and perforations on rear vehicle sub frame that can cause risk to driver of accident or injury. Mbusa is offering to replace sub frame part # 212 350 38 05. However dealership advised mbusa is not offering to replace corroded brake lines or brake fluid exchange, and would need to come out of pocket. Mbusa failed to notify me of safety defect. Vehicle was purchased from mb of arlington, va in 4/2019 however dealership sold vehicle that is dangerous to drive. The vehicle also has additional safety defects such as a passenger tail light that does not work, and a license plate light not functioning. Dealership wants an additional $1500 to replace these (2) lights. Vehicle has low mileage at 60,000 and was purchased with 35,000 under mb cpo program. I am very disappointed in Mercedes Benz and have never had so many quality and safety issues with any of my prior e-classes before. I contacted mbusa and opened up a executive care escalations case [xxx}. There was no warning lights of the impending safety feature. The level of rust on the sub frame is horrifying, and this vehicle should never have been sold to me under mb cpo. In addition, the vehicle engine is leaking oil in multiple places and could catch fire in any moment. I have never seen so many issues on a vehicle with low mileage, especially with a mercedes. Dealer is refusing to assist with cost, and wants 2k+ to replace engine gaskets. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On 11/24/23 Mercedes Benz had replaced my subframe which was part of a safety recall. When I arrived home after picking up my vehicle, there was a loud bang from under the vehicle. I immediately called the service department and told them about what happened and also complained that the steering wheel was cocked to the left and pulling in that direction. My service advisor john advised me to bring it back the next day which I did. They never told me what caused the loud bang, but they did say another front end alignment was done. The vehicle still continued to pull and the steering wheel was still off center. On [xxx] I took my car to mr. Tire for a tire rotation because the car continued to sway and jolt when going over bumps. It also made a popping noise when making a sharp turn. Then on [xxx] as I was driving, the car pulled or slid to the left. In order to keep from crashing into another vehicle, I pulled the wheel right causing me to run over the medium and almost crashing into a building. I was extremely shook up and in disbelief. Has this type of thing ever happened to anyone else before after the subframe was replaced? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving on a highway approximately 65 mph. Had to break fairly hard due to unexpected traffic. When breaking, my car fishtailed and I thought I was going to hit the vehicle in front of me. I immediately took my car to my independent, mercedes-certified repair shop. My mechanic informed me that it was a problem with the rear subframe. I then took it to mercedes for an inspection. They confirmed that the rear subframe was rusted and needs immediate repair. I was told not to drive the vehicle as it is extremely unsafe. Mercedes is aware of this problem. There was a class action lawsuit filed in February of 2023. Mercedes supposedly informed owners of the potential problem, but I was never notified. I only became aware of this dangerous subframe problem as a result of this incident.

Rear sub frame corroded which results in unsafe driving, corroded brake line which results in unsafe driving. Blind spot sensor in the bumper is corroded due to no protection against environment.

The subframe corroded causing an unsafe potentially hazardous condition. Also the brake line was were corroded causing imminent brake failure. The rear springs rusted from the corrosion subframe defect. . Mercedes required 2800 dollars from me to remedy the problem.

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.

Car control was diminished and braking caused car to pull hard. Creaking noise from rear end. Removed rear wheel to find frame had perforation where rear wheel has linkage to frame.

My rear sub frame has major corrosion and is broken on the driver side, the passenger side about to go soon. My vehicle only has 154000 miles on it.

The contact owns a 2013 mercedes-benz E350. The contact stated while driving approximately 10 mph, the brake pedal was depressed; however, the vehicle failed to respond, and the vehicle veered into another lane. Additionally, while her son was driving at high speeds, he detected a shimmy in the front end. While approaching a stop, the brake pedal was depressed; however, the vehicle was slow to respond. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the rear subframe needed to be replaced. The vehicle was repaired under warranty. The manufacturer was contacted but no additional assistance was provided. The failure mileage was approximately 30,000.

Per the technician: "the rear subframe is rusted out and the lateral strut arm is starting to break away". Because of this issue, the car unknowingly presented a safety risk to occupants and other drivers. A failure of the subframe or connected components could have resulted in a serious accident. Photos are attached. The vehicle is currently available for inspection upon request. There were no warning indicators to this issue. The issue was found only because the car was being serviced for brake pads. Mercedes benz USA customer care said there was no recall or other warranty covering the issue and said the vehicle was outside their "good will assistance program". The vehicle is no longer able to be driven.

Power steering is makes winding noise and very wobbly wood grain interior is turning white emissions problems.

During maintenance check, mechanic indicated rust on the rear subframe that can lead to failure. Failure on this car would cause a puncture of the fuel tank due to car design. Upon further research, this is a well known issue with mb and is covered as a recall in all countries other than the us. Please encourage Mercedes Benz to do the right thing and issue a recall for this defective component, to avoid serious accidents.

Same problem that many others have reported. Took car dealer for a battery. Was told subframe is rusted and about $5000 to fix and that if not fixed could lead to car failure. 1) why has mercedes not informed the many thousand 2010-2014 c-class and e-class drivers affected by this dangerous defect. Many do not take their cars to the dealership for service anymore and could miss the problem until it is too late. 2) these cars have been recalled in germany and elsewhere. Why not in the united states? 3) is this situation up the the standards of NHTSA? if not why has a recall not been ordered? 4) is there a difference in weighing customer safety against company bottom-line in the us compared to other countries? thanks.

The subframe is rusting in four places in the area of the wheels. If the frame breaks I could lose control of the vehicle.

Our mechanic reports a dime-sized rust hole in the rear subframe.

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.

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).

Subframe is rusting and will cause structural failure. If failure happens car stability will be compromised and therefore cause an accident. Detected and confirmed by independent service center. Not inspected by dealer or ins. No warnings triggered since system not set up for that detection. Part in such high demand that there is a 10 mo wait via several dealer parts depts.

The rear subframe of this vehicle has rusted on a seam and is cracking. I do not know if the seam is a weld or a bend in the metal. There is no corrosion on rest of the underbody. I do not know when the condition started. I noticed it upon braking. It felt as though the rear end of the vehicle was going to swing out around me. It started about three months before this report and got progressively worse. It was only noticeable when braking firmly from moderate or higher speeds, I have taken the vehicle to the mercedes dealership and they advise the fault is not covered by warranty. A google search would indicate that this is a problem occurring worldwide with mercedes vehicles that use the identical sub frame to that in my vehicle.

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 (budy lim) 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.

The rear sub-frame involving vehicle stability under braking and turning. A component that should remain attached to the vehicle has broken off due to corrosion. My vehicle is not that old that a key structural component of the car should break at the weld/attachment point. I have video of this defect. But its greater than 10mb and will not let me upload it is there an email I can send it to ?.

The rear subframe failed as a result of pre-mature corrosion while traveling at 70mph. Control of vehicle was lost and could easily have led to a multiple fatality incident if not for luck. The problem has been reproduced in many mercedes models around this model year and mercedes is well aware of the issue with their inferior subframe. Ntsa needs to order a recall from mercedes as class action lawsuits are going to be put together if nothing is done. There was no warning that this subframe was going to fail.

Upon routine maintenance visit to manufacturer dealer, was told that rear subframe assembly was corroded and could fail. Took vehicle to other local manufacturer dealer and they confirmed the same. Was able to catch the issue before incident, but was told subframe failure was imminent.

2014 E350 with 41,000 miles. Rusted subframe and was informed that it represented unsafe and risky driving conditions. Reported this to manufacturer as, apparently, it is a very common problem with certain mercedes classes. No recall and very expensive fix ($4500)! not my idea of a safe and reliable car, as mercedes likes to advertise. Consumers should not be responsible for manufacturing defects/ poor quality of materials used . . . . . And should definitely not be exposed to unsafe conditions when operating their vehicle!.

The sunroof detached and the water from the rain leaked through the faulty sunroof into the interior doors, floorboard and dashboard. This happened to both the passenger side and the driver side. It was repaired out of pocket because of the hazard and lack of dealership accountability. Because the dealership wanted to charge $1000 to provide a water intrusion inspection so we went to an a mb authorization independent mechanic to repair the vehicle. This leaking lead to the growth of mold and lack driver visibility. Lastly they were no warnings before the leak happened.
