Rear camera fails unexpectedly when placing car in reverse

The brake lines on my car rusted out from the brake booster all of way to the rear calipers. This is the third time it’s happened to me as I’ve owned multiple E classes. If Mercedes-Benz covers the subframe, why is the brake lines which are located right above said subframe not covered?

The rear subframe got separated from chassis. I was driving to work and had to hard brake to void a collision with another vehicle all of a sudden vehicle shifted to the left and I ended up on a curb. Further inspection vehicle`s rear subframe rotted out due to rust. Also, both rear brake lines from abs module to calipers are damaged due to corrosion. I ended up replacing both brake lines and did not think too much of it and now I see a lot of people complaining about both brake line corrosion and subframe separation or excessive rust, casing rear subframe to fail. It is a very serios safety issue and Mercedes should hold accountable for these failures. My vehicle is 2012 Mercedes E350 and only has 118k miles on odometer. I have attached pictures for the rear subframe for your review, but I did not take any pictures of the brake lines due to limited space to get my camera between the body and the rear subframe.

Brake line is thoroughly corroded, went to a repair shop, when they brought it back down, the Subframe collapsed. Mercedes has a 20 yr warranty on the subframe so they will cover that but want another $3K to fix the brake line that was obviously tied to the same mfr issue that the sub frame was in regards to rusting. Dealer won't take any responsibility for anything but the subframe.

The contact owned a 2012 Mercedes-Benz E350. The contact stated that while attempting to shift to drive(D), the gear shifter detached from the steering column. No warning light was illuminated. Neither a dealer nor an independent mechanic was contacted. The vehicle was not taken to a dealer or independent mechanic to be diagnosed. The vehicle was not repaired. The vehicle was towed to the residence by AAA. The manufacturer was not notified of the failure. The failure mileage was 420,000.

I recently took my 2012 Mercedes-Benz E350 to an authorized Mercedes-Benz dealership after experiencing corrosion of the rear subframe. The dealership confirmed and is servicing the vehicle under an active recall notice that extended the original New Vehicle Limited Warranty from 4 years/50,000 miles to 20 years /unlimited miles. After removing the subframe for repair, they observed serious corrosion of the brake lines. There had been no warnings or symptoms to alert me to any corrosion problems with the brake line prior to this. Most likely, the issue would not have been discovered if the dealership had not removed the subframe. The dealership advised me that this issue requires immediate service due to safety concerns (potential failure) as the braking system could fail while driving the vehicle. The cost to have the work done is $5800. Beyond the dealership service center, I'm not aware if brake line has been inspected by others (engineers) in Mercedes-Benz. However, this issue appears to be frequently observed in vehicles experiencing the rear subframe corrosion issue.

Gasoline Fuel System problem of the 2012 Mercedes Benz E350. Driver side fuel leak was excessive. Leak caused an excessive amount of gas to spill while driving on a 600 mile long round trip to St. Louis. The fuel filter sending unit had numerous stress cracks in the plastic. A massive failure was looming. I have pictures and have documented the failure. 2184700194 was the original part and now has changed too 2184700994. A component should be easily inspected to prevent such a dangerous situation. For the past 13 all services work was preformed by Mercedes.

I have a 2012 E350 with less than 95000 miles and I see these vehicles were recalled in the past for their fuel tank manufacturer malfunction but my VIN number was not included. This car went numerous times to the mechanics and the fuel components fixed but it still leak gas and smells even when I do not drive the car. I spent over $15000 on this matter. This is now becoming a safety issue for me and my neighbors. I don't know what to do. Here is what happened. All began February 2023, I towed the car to an approved MB mechanics who said fixed the car. 9 month later, I brought the car back for the same issue. Strong fuel smell. The attachments for repairs will show the work done. Some repeated and recharged to me. The following year April 2024, I woke up one day with a fas leak all over my drive way and a strong smell of gas. I had the car towed for a repair cost of $7754 total. I am constantly having the same problem with the car and wanted to alert here to bring Mercedes Benz awareness to their faulty parts putting consumer lives at risk.

Recall exists related to a potential issue with the high-pressure fuel pump, which could lead to engine stalling and increase crash risk. My 2012 Mercedes E350 stops the engine in the middle of the road couple of times and for some reason, its stops or shut off the engine completely. The last time I was pulling out on the main road and stop right there. I made a big traffic, and I was scared because I cannot start the car. The guy stops and help me to push out of the road, but we cannot push the vehicle unless someone is inside the car. If I go out, it will automatically go on "park" and cannot push the car. When you check the dashboard the check engine light is not on. 2nd incident I bring this car to Mercedes Benz Dealership, and I told them that there is something wrong in my car, I explain what was wrong but, the guy I talk to, told me that if the check engine light is not coming on, my car is fine. I repeated that the car stops ones in a while when the temperature light is on inside the dashboard and the engine shuts off. He told me if the check engine light turns on then I bring it back. I show the code reading but the same thing he said. I left and went back home and suddenly I get stranded again; I got stock in the middle of the road for 3 to 4 minutes. I start the car and suddenly the car starts and find the nearest place to pull over. I let it call down for couple of hours and start again, the car starts and try to go back home. When I was in the interstate hwy. My

[XXX].The engine intake manifold on our 2012 Mercedes E350 (64,000 miles) EXPLODED with enough force to bend the hood up 2 inches. It was a damp cold morning & the engine had not been started in 12 hours. The car was not locked & the key fob was nowhere close. The fuel level was under 3/4 full. This happened when wife went to get something out of the car and when she pulled the passenger door handle to open - B O O M !!!! If this happened 30 minutes later, I would have been under that hood checking the fluid levels for a trip to San Francisco. I WOULD HAVE BEEN SERIOUSLY HURT OR KILLED!. It was towed to Mercedes-Benz of Carlsbad, Carlsbad California on [XXX] & they have not been able to identify the cause. They could replace the broken parts at the cost of $8,000 but that doesn’t fix the problem. And if it happens again & hurts or kills someone, they could be held liable. Similar intake explosions have occurred on these Mercedes engines but Mercedes is denying any knowledge even though it’s clearly a dangerous design flaw in this intake system.

I am writing in regards to the 5 vehicle recalls that were for the make, and model of my car that is showing as having no recalls for. The recalls involved air bags, air bag software, fuel filter flange, and I am also wondering with the driver headrest deployment module if that is associated with an airbag module; as when I had purchased the vehicle I had found out that both my airbag modules had malfunctioned with showing the srs lights on the dash. I was told that Mercedes of Sarasota, FL had replaced the passenger airbag module by Mercedes of South Orlando. When asked for a printout verification of this repair showing to be completed; they said they couldn’t provide me with this information. As proof of the service to being completed could not be provided. I had tken my car to their to have them look into this, and the tpms sensors showing malfunctioned; communication error message, and they couldn’t figure out what the problem was causing this. I had to take my car to an auto electrician to find out the problem; that I had found out that a 100 amp fusible link had blown, causing all those problems with also the roof wasn’t working. Along with I was smelling fuel. I found out about the recall for these items after getting them repaired out of pocket by the auto electrician Mike from Peak Audio, and Electric, and as to the fuel filter flange I had to pay like $1,200 to replace as they had replaced the fuel level sending unit that include the fuel filter flange. I would like

2012 e350 both rear brake metal lines rusted out January 2025 brakes gave out. This is definitely connected to the rear subframe rusting too.

Rear subframe corrosion and in addition, rear break line corrosion.

Recently, I have noticed a strong gas smell emanating from the rear driver’s side of the vehicle. Upon further research, I discovered that there was an open recall affecting Mercedes E-Class vehicles of the same year for a similar issue. However,my vehicle’s VIN is not included in this recall. Given that my vehicle is experiencing the same problem described in the recall, I am concerned about the safety implications and believe this matter warrants immediate attention. I would like clarification on why my vehicle is excluded from the recall despite exhibiting the same issue. Additionally, I would like to know if I am expected to pay out of pocket for repairs related to what appears to be a manufacturing defect acknowledged by Mercedes-Benz for other vehicles of the same year and model. I kindly request that this matter be escalated for review, and I look forward to your prompt response. My goal is to ensure the safety of my vehicle without incurring unfair expenses for a known issue.

The failure mileage was approximately 105,000.

Rusted/leaking brakes lines to rear of vehicle.

The contact owns a 2012 Mercedes-Benz E350. The contact stated while driving at various speeds; when the brake pedal was depressed, the brake pedal failed to return to the original position. The contact stated that upon inspection, the brake pedal felt abnormally loose and there was a brake fluid leak present. The vehicle was taken to an independent mechanic where it was lifted and was noticed that the sub-frame was rusted. An appointment with the dealer was scheduled to inspect the vehicle as a second opinion. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 160,000.

The fuel pump filter failed and myself and grandchildren became sickened by the fumes. Once the back seat was removed and inspected by an independent source you could see how the gas had leaked into this area. There was no warning lights or messages that had appeared. This problem could easily ignited a dangerous fire situation.

The contact owns a 2012 Mercedes-Benz E350. The contact stated that the filter flange was cracked. There was an abnormal fuel odor detected. The vehicle was leaking fuel near the fuel tank onto the ground. After refueling and driving five miles, the fuel was depleted to half a tank. There were no warning lights illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 12V557000 (Fuel System, Gasoline). The contact called the local dealer and was informed that there were no open recalls on the VIN. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 143,459.

The rear brake lines on my 2012 Benz E350 has a lot of corrosion and one of the blowout while stopping from 25mph to a complete stop. Upon further inspection, it was completely rusty in many places. Mercedes needs to address this issue because its unsafe rather danger to drive.

Rear subframe has rust perforation causing instability and stopping issues with the vehicle.

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.

I purchased the car late April. I drove the car for three or four days and started noticing a rattling coming the front right part of the car (passenger side.). I chatted with the warranty company (SilverRock.). They asked me to take it to a Meineke auto repair facility in Olympia, WA. Meinke’s mechanic diagnosed it as a loose component involving the brake caliper. He informed me they were covering it under the warranty, & asked me to bring the car back on Wednesday as he was short staffed. I brought the car back on Wednesday, it was there all day. He called late in the afternoon and informed me they found the problem and that SilverRock had amended the claim and refused to cover it. Told me it needed new brakes for 800+ bucks. That being said it was also sold to me with gouges out of several tires. Of which I have photos. This is inexcusable it is also a safety issue.

My check engine light has been on for about a year, I have been told by both the dealerships here in Memphis/Collierville that as long as the light is an orange color there is nothing to worry about but it has been on consistently for about a year. I had a Diagnostic test done on [XXX] by Dr. Benz Affordable Mercedes Benz care and it was revealed that ME control module, oxygen sensor, engine wiring harness has oil intrusion all throughout. I would hate to attempt to drive my vehicle and all of a sudden it is severely damaged because of this. I feel this may be a very costly expense and would like some assistance in taking care of this matter. I love my car and have not had any problems, and hope to have it several years more. I only have 116,038 miles on this 2012 vehicle that I purchased in 2015 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

BRAKE LINES TO THE REAR HAVE CORRODED AND CAR CAN NOT BE DRIVEN.

On April 29, 2024, I was driving my 2012 E350 Mercedes and the brakes failed upon leaving an appointment. There was less than 10% stopping ability. Fortunately, I was able to use my transmission toggles and Emergency brake as back up, if needed. I immediately stopped to pick up brake fluid and filled the reservoir which was virtually empty. Drove the vehicle home, left it parked for two hours and then tried to then drive it again but to no avail. The system had "bled" all over my garage floor and driveway. As such it was taken to the dealership on a flatbed. Estimated repair... $1,700 This follows having to replace the cargo springs due to corrosion and breakage, the rear suspension sub assembly currently being replaced due to corrosion which Mercedes acknowledged is a problem and is covering under an extended warranty. In my mind, all of this is related and certainly a safety concern, beyond the expensive repair costs already and now currently being incurred. Can you help?

On my recent visit to my trusted independent service center, which specializes in Mercedes-Benz, they noticed serious corrosion problems. There were no symptoms to alert me to any problem. Also, I never received the notice from MB so how would I know? My mechanic asked me to sign a waiver (which I never have had to do before) that stated the rear subframe was rotted completely through; needs to be replaced ASAP; and is unsafe to drive. The rear brakes lines also had corrosion. This tells me the car is unsafe to drive, and must be fixed. It seems that MB issued an "extended warranty" to cover the rear subframe, but not the rear brake lines. I contacted MB Corporate who said they 'may' offer some assistance. I have an appointment next week with a MB dealer who must provide an estimate of the damage and cost to MB for their approval before doing any work. As a result of learning what's eating my car underneath, I won't take it on any extended trips. I really am afraid of something bad happening. And it has, to many others. No one should ever have to get into a car and worry about these two safety issues. It’s very important that Mercedes-Benz recognizes its responsibility to not only its customers, but to all the other drivers on the road who can be negatively affected through accidents caused by these corrosion issues.

The contact owns a 2012 Mercedes-Benz E350. The contact stated while operating the vehicle, there was an abnormal fuel odor inside the cabin of the vehicle. The cause of the failure was not yet available. The manufacturer was notified of the failure. The local dealer was not yet contacted. The contact was informed that the VIN was not included in the NHTSA Campaign Number: 12V557000 (Fuel System, Gasoline). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 183,000.

Brake line corroded under protective cover. Was driving and felt mushy brakes and came home to almost no brake fluid. Found leak under driver side door. Kind of weird because it’s under a cover.

The top of the fuel pump is leaking (driver rear side, under the seat) and the leaking can be seen outside of the car as a moisture on the underside of the car. The fuel filter side (passenger side, under the seat) has a small amount of fuel moisture. The current mileage on car is 76,620 miles.

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 car was parked in the driveway outside. In the AM when getting into the car I saw that the drivers HEAD-REST had engaged by itself during the day. There was no airbag only pieces of plastic and springs on the seat. The headrest was just hanging there and in no way could be reset. Car was taken to the dealer for repair. Extended warranty would not cover it stating airbag issue even though the headrest has no airbag. Dealer is repairing the headrest - total cost $1,800. Mercedes also does no want to cover it since the auto is a 2012. The problem was reported to Mercedes and they stated that there was no recall on the item. And that is it. Spoke to dealer who indicated that they have seen this problem before but not widespread. And that is it!! Mercedes quality is one to be desired.

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.

Hello, A manufacturer should understand that Timing Chain is a vital component in an engine, an so should not say just tell consumer that it goes bad at a particular milage., As such in my MB E350 2012, is difficult to start the car and i think that this should be looked at. Thanks

The rear subframe / axle carrier on vehicle failed. Rear subframe / axle carrier had significant corrosion / rot and large rust holes present. Also, the rear suspension parts & air shocks were seized / corroded to the rear subframe. Dealer advised vehicle was unsafe to drive.

Car won't go forward or reverse smoothly. It acts like a dead pedal then lurches. I traded pain with a safety barrier backing up when it suddenly went backwards. Also sometimes when entering the highway or passing a car it will go into limp mode. Can only be cleared by restarting car. Very dangerous.

My 2012 Mercedes E350 has rear sub-frame is starting to rust/corrode and I need to replace it within 3 months. This could cause the rear end to break free and forcing the back of the vehicle to swerve while braking. My Mercedes authorized repair shop stated that similar problems have been identified in other models using same rear subframe and they have replaced them. I have 143K miles and the car is garaged year round. It will cost $5K to repair. Mercedes USA will not fix this for free while all European Mercedes group repair this for free as a defect.
