SERVICE BRAKES
Brake pedal went to floor and brake function became significantly impaired and dangerous. Took car to local shop who diagnosed as failed rear brake lines, and most of the entire length of the rear lines were in very bad condition. Car only has 104k on it. It doesn't take much searching on the internet to see how widespread of a problem this is, and even the dealer admits they do multiple of these per week on the W212 (and a few other platforms are affected). The front lines seem to be in good shape so there does seem to be a design issue here.

STRUCTURE:BODY, EXTERIOR LIGHTING, ENGINE
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)

ENGINE
This has happened once before and I reported it then. This time I was stopped at a stop light and when I pressed the accelerator to go when the light turned green, the engine was off and would not go. The screen only said "malfunction" and no error codes (as before). I pressed the start button to turn the car off and then restarted it. It was fine after that. I have left a message with my service agent at my Mercedes dealership. I had previously told them that this had happened before. I am concerned about the safety of a car the stalls like this. Please investigate. I see other reports about this from E class car owners on line in various forums.

ENGINE, UNKNOWN OR OTHER
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)

SERVICE BRAKES
All of a sudden my brake error lights went on while driving to work. By the time I could stop at a garage on the way my brake fluid was very low and more was added. Had to again add more when I got home just so I could take the car to my repair shop. Independent repair specializing in mercedes identified 4 leaks in rear brake lines. Pictures show that all leaks are at or adjacent to clips attaching to the car. Something is wrong with the design or materials for this to happen consistently in the same car. Mechanic said this isn't expected until cars get at least 100k and shouldn't be consistently in the same connections. The fluid was draining so fast that if someone were driving a longer distance they may not have the ability to refill before brake failure. This is a safety hazard to have so many material failures at the same area of the brake lines.

ELECTRICAL SYSTEM
While driving in traffic there were loud popping and crackling sounds from the rear speakers. Then smoke appeared and an acrid burning smell. The smoke and loud sounds continued after I pulled over and turned the key off. I removed the fuses for the sound system and it remains inoperable. I went home and searched for this problem on the web and discovered that it is a common problem on 2014 Mercedes E350's. Despite this being cited as a common problem by owners, there is no recall. I called Mercedes-Benz USA and they reported that they were not aware of this problem. This event was very alarming and could have caused an accident when the smoke was coming into the passenger compartment. I believe it qualifies for a recall.

SERVICE BRAKES
I bought my vehicle to the Mercedes dealership to get the rear subframe replaced under extended warranty due to it being rusted and broken from the rear suspension attachment points. While the Mercedes technician had the subframe removed he noted that the rear brake lines which are routed under the body and between the subframe had significant rust/corrosion on them.

I was parking and the 360 view sensor did not come up. When I tried to back out and move forward again, I realized the back up camera would not come on. I turned the car on and off and then tried again to reverse to engage the camera but was instead given a message that says system inoperative.

ENGINE
I am writing in regards to a constant issue that a great percentage of people including myself, are experiencing with the engine within the 2017 Mercedes E300. The cam adjusters are easily going bad or are malfunctioning causing the timing in the motor to be defected which makes the car stall and shut off even while driving. Giving that this is happening to a great amount of people with this particular vehicle across the US, we feel that mercedes benz should take some responsibility in fixing this issue and not just post bulletins on the problem, cause its a safety issue and it costs people alot of money for a defect of this sort.

SERVICE BRAKES
The brake fluid lines rusted. The front line, due to the rusted hole, leaked brake fluid to the point that the car had little to no braking ability. In addition, the computer warning did not activate. The car was taken to the dealer, where they verified that the computer warning did not activate, and that the brake fluid had bleed out causing the vehicle to have no brakes. This is a dangerous situation! The car is a little over 10 years old, has about 54,000 miles. Had I been on the highway and tried to make a hard stop, I could have had a terrible accident. The dealer now has the car for repairs, but there are many other E350 that have posted online that they have had an identical situation where the brake fluid lines have rusted out! This leaves the driver, without any warning, to be put in a life threating situation!

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
On [XXX] I was driving and the vehicles stalled in the middle of the street, I couldn’t start it back. I managed to contact AAA and had the vehicle towed to my home because it around 6pm and auto repair shops were closed. Next morning I had AAA towed the vehicle to a local auto repair shop and they told me that fuel pump failed. It would have been very dangerous if we were driving on the freeway, not to mention I had my 85 year old mother in the passenger seat. Please help me as I am sure what I need to do now. It’s a Mercedes-Benz model E350 2008. I can be reached at [XXX] my name is [XXX] . My car has 87,200 miles. Thank you in advance for all your helps.

SERVICE BRAKES
I am losing brake fluid. Likely from rotted brake lines. Was given a quote attached below for repair of rotten brake lines 2 years ago. My friend has the same vehicle (a 2014 model) and had to replace brake lines for the same issue. I've never heard of break lines rotting and leaking on another make of vehicle after only 8 years of use at 70K. The car is always garaged, washed weekly and currently at 91K miles. I believe the coverage of the rear subframe should be extended to the break lines for this model of vehicle since it is a commonly reported problem per the dealer.

VISIBILITY/WIPER
Recently (April 2024) we've noticed water drops forming on the inside of the vehicle along the top of the front windshield after a rain. Pushing outward along the top inside of the windshield glass indicates some movement of the glass. This applies all along the top inside of the windshield and not just one spot or area. So far, we have only observed water drops and have not observed any water pooling or puddling yet. We have not yet contacted a dealer; however we have conducted online research that strongly suggests that the windshield urethane adhesive seal is failing. Additional online information suggests that Mercedes had identified windshield urethane adhesive seal batch issues with certain 2016 E350 models. There have been no warning lamps or indicators from the vehicle. We have not observed any vehicle performance issues other than hearing a slight general whistling sound while driving at highway speeds above 55 mph, but that has been unchanged for years so it is likely not related to the windshield seal. The vehicle currently has approximately 30,000 miles on the odometer, and we are the second owners, having purchased it as a certified pre-owned vehicle with about 10,000 miles.

SERVICE BRAKES, SUSPENSION
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?

SUSPENSION, STRUCTURE:FRAME AND MEMBERS
The contact owns a 2014 Mercedes-Benz E350. The contact stated that while the vehicle was at an independent mechanic for an oil change, the contact was informed that the rear driver's side control arm was severely corroded and had detached from the subframe. The contact was also informed that the failure caused premature tire wear on both rear tires. The vehicle was then towed to the dealer, where it was determined that the subframe and rear driver's side control arm needed to be replaced. The vehicle was not yet repaired and remained at the dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 110,000.

AIR BAGS
Both driver and front passenger headrest airbags have deployed for no cause. This is is the second time this has occurred on both sides. No collision occurred in both incidents. First time it occurred under warranty and Mercedes fixed the issue. This time it occurred again and the car is not in warranty. Without functional headrest airbags the safety is greatly compromised for the occupants of the car and can lead to fatal incidents. It seems like a recurring problem with this model as it has occurred twice over 9+ years and both times there was no collision etc.
